La Prairie’s Fur Trade & Ties That Bind — Leber, Bourassa & Pinsonneau Families

 From a conversation with GROK…

What can you tell me about Francois Bourassa b. 1659 Luçon, Eure-et-Loir, Centre, France; d. 9 May 1708 La Prairie, Quebec, Canada And his wife Marie Le Ber b. 6 Dec 1666 Montréal, Quebec, Canada; d. 23 Dec 1756 La Prairie, Quebec, Canada?

François Bourassa (c. 1659–1708)

François Bourassa, sometimes spelled Bourassart or Bourasseau, was born around 1659 in Saint-Hilaire-de-Loulay, near Luçon in the Poitou region of France (modern-day Vendée department; the provided location of Eure-et-Loir may be a common genealogical error, as Luçon is historically in Poitou). He was the son of François Bourassa (c. 1630–aft. 1684), a laborer or farmer from Poitou, and Marguerite Dugas (c. 1635–c. 1698). Little is documented about his early life in France, but he emigrated to New France (modern Quebec) as a young man, likely in the 1670s or early 1680s, during a period of active French colonization and fur trade expansion.

Upon arrival, François settled in the frontier areas along the St. Lawrence River, where he became involved in the fur trade—a vital economic driver in New France. By 1683, he was recorded in Contrecœur, a seigneury east of Montreal. He worked as a voyageur (canoe-based fur trader), transporting goods and pelts between French outposts and Indigenous trading partners. Notable engagements include:

• In 1686, a voyage to Hudson Bay for the Compagnie du Nord, a major French trading firm.
• In 1687, transporting furs to his future brother-in-law, Jacques Le Ber, a prominent Montreal merchant and partner in the influential Le Ber-Le Moyne fur trading house.
• In 1688, hired by René Legardeur de Beauvais to trade with the Ottawa (Odawa) people in the pays d'en haut (upper country).

These expeditions were perilous, involving long canoe trips through rapids, forests, and hostile territories, often with Indigenous allies or guides. François's skills as a voyageur helped him build connections in the colonial elite.

Marriage and Family Life

On July 4, 1684, François married Marie Le Ber at Fort Saint-Louis in the seigneurie of Chambly (the marriage record was registered at Contrecœur parish). The ceremony was witnessed by fellow Fort Saint-Louis residents, including Jean de Paris, Alexandre Dumesnil, Jean Peladeau, Gedeon Petit, and Pierre Salvay—many of whom were soldiers or traders. At the time, François was about 25, and Marie was 17. The couple initially lived at Fort Chambly before settling in La Prairie-de-la-Magdeleine (now La Prairie, Quebec), a strategic fur-trading hub south of Montreal on the St. Lawrence River, near the Iroquois territory.

In La Prairie, François shifted focus to farming on a plot adjacent to the parish church of Nativité-de-la-Prairie-de-la-Magdeleine, though he occasionally returned to trading. The family home was modest but central to the community. Tragedy struck during one of his absences: in September 1693, Marie believed him lost at sea or killed, and she was listed as a widow in parish records. François returned safely the following year, after which he largely stayed home to support his growing family.

François and Marie had at least nine children, many of whom carried on the fur trade legacy or married into prominent Quebec families. Here's a summary of known children (all baptized at La Prairie unless noted):

Child	Birth/Death	Notes
Charles Robert Deslauriers	b. 1683 (Fort Chambly) – d. unknown	From Marie's previous marriage; adopted the Bourassa name.
François	b. Sep 30, 1685 – d. Aug 12, 1708	Voyageur; died young, shortly after his father.
Jean (Pinsonnault Lafleur)	b. 1682/1687? – d. c. 1743	Likely a variant or error; possibly merged records; became a farmer.
René, dit LaRonde	b. Dec 21, 1688 – d. Sep 7, 1778	Prominent voyageur and trader; wintered with explorer La Vérendrye; father of several traders who expanded into the Great Lakes region.
Agnès Gagné	b. 1692 – d. 1719	Married into the Gagné family.
Marie-Élisabeth	b. Feb 25, 1695 – d. Nov 20, 1766	Married Jean Pinsonnault dit Lafleur; ancestors of many in Quebec.
François-Joachim	b. Apr 10, 1698 – d. Mar 21, 1775	Fur trader; married twice (Marie-Anne Deneau in 1721, Marie Susanna Lefebvre in 1735); had 10+ children.
Charles-Joseph	b. Jun 13, 1703 – d. unknown	Limited records; likely stayed in La Prairie.
Antoine	b. Mar 23, 1705 – d. c. 1786	Farmer and trader.
Suzanne	b. Mar 23, 1707 – d. unknown	Youngest; married locally.

The family endured hardships, including epidemics and the constant threat of Iroquois raids, but prospered through trade networks.

Death

François died on May 9, 1708, at age 49, during a smallpox epidemic sweeping New France. He passed away at the Hôtel-Dieu hospital in Montreal and was buried the same day at Notre-Dame parish. His burial record lists him as "François Bourassart, de La Prairie de la Magdeleine," with no age given. He left Marie to raise the younger children alone; his eldest surviving son, René (age 20), took on family responsibilities.

Marie Le Ber (1666–1756)

Marie Le Ber (variants: Lebert, Le Ber, LeBert) was a resilient colonist born in the heart of New France. She was baptized on December 6, 1666, at Notre-Dame-de-Montréal parish, the daughter of François Le Ber (c. 1626–1694), a prosperous merchant and interpreter who arrived in Montreal in 1657, and Jeanne Testard (c. 1643–1723), from Rouen, France. Her godparents were Mathurin Josset and her aunt Marie Le Ber. The Le Ber family was wealthy and influential: her father owned trading posts and served as a militia captain, while her uncle Jacques Le Ber was a key fur trader and philanthropist. Marie grew up in Montreal's Ville-Marie settlement amid Jesuit missions and Indigenous interactions.

First Marriage and Early Widowhood

At age 15, Marie married Charles Robert Deslauriers (c. 1655–1683), a soldier at Fort Chambly, on an unspecified date around 1681–1682. They had one son, Charles Robert (b. 1683). Charles died shortly after, likely in military service or from illness, leaving Marie a widow at 16.

Second Marriage and Life in La Prairie

Her union with François Bourassa (detailed above) brought stability and a large family. After François's death, Marie managed the household and farm in La Prairie with remarkable longevity and fortitude. She witnessed the transition from French to British rule after the 1760 Conquest and lived through the early French and Indian War (1754–1763). Parish records describe her as a devout parishioner at Nativité-de-la-Prairie-de-la-Magdeleine.

Death

Marie died on December 23, 1756, at age 90, in La Prairie during the ongoing Seven Years' War. She was buried the next day in the parish cemetery. Her long life allowed her to see grandchildren and great-grandchildren establish the Bourassa line across Quebec and beyond, including in the fur trade and later in politics and arts (e.g., descendants like Napoléon Bourassa, a 19th-century painter).

Legacy

François and Marie's descendants numbered in the thousands by the 19th century, spreading across Quebec, Ontario, and the U.S. Midwest. The Bourassa family became synonymous with the voyageur tradition—René and his sons traded as far as the Red River and Lake Superior—and later produced notable figures like journalist Henri Bourassa (1868–1952), a founder of Canadian nationalism. Their story reflects the grit of early French-Canadian settlers: immigration, trade risks, family endurance, and adaptation to colonial life.

More on René Bourassa's expeditions...

René Bourassa dit LaRonde: A Prominent Voyageur and Fur Trader

René Bourassa (baptized December 21, 1688, in La Prairie, Quebec; d. September 7, 1778, in Montreal) was the eldest surviving son of François Bourassa and Marie Le Ber, inheriting his father's legacy as a key figure in New France's fur trade. Known as "dit LaRonde," René became one of the most active and adventurous voyageurs of the early 18th century, operating primarily in the pays d'en haut (the "upper country," encompassing the Great Lakes region and westward territories). His expeditions combined legitimate French trading ventures with risky illicit activities, driven by the lucrative beaver pelt market. Overhunting near Montreal and higher prices from English buyers in Albany pushed him westward, where he partnered with merchants, hired engagés (contracted laborers), and supported exploratory efforts by figures like Pierre Gaultier de Varennes et de La Vérendrye.

René's career spanned over four decades, from his early 20s until semi-retirement in the 1740s. He married twice—first to Agnès Gagné in 1710 (three children), then to Marie-Catherine Leriger de La Plante in 1721 (five children)—and his sons, particularly René Jr. and Ignace, later took over his operations at Michilimackinac (Mackinaw City, Michigan). He owned property in Montreal, including a house, a lot in Fort Michilimackinac, and enslaved laborers to manage his holdings. His expeditions were marked by peril: ambushes, tribal conflicts, and harsh winters. Below is a chronological overview of his major known expeditions and trading activities, drawn from notarial contracts, colonial records, and explorer journals.

Key Expeditions and Trading Ventures

Year(s)	Destination/Region	Details	Outcomes/Notes
Early 1710s–1721	Ottawa (Odawa) territory and Michilimackinac (Michigan)	As a young voyageur, René followed his father's paths, paddling canoes laden with trade goods (e.g., cloth, tools, alcohol) to exchange for furs with Ottawa and other Algonquian groups. In 1710–1720, he made seasonal trips from Lachine (near Montreal) to Michilimackinac, the fur trade hub at the Straits of Mackinac. These were standard pays d'en haut routes, covering 1,000+ miles via the Ottawa River, Lake Huron, and portages.	Built his reputation; earned profits from beaver pelts, which were overabundant but declining near settled areas. Likely hired by uncles like Jacques Le Ber for initial contracts.
1722	Albany, New York (illicit trade)	Ventured south from Montreal to Albany, smuggling furs to English merchants who paid double the French price (up to 2 livres per pound of beaver vs. 1 livre in Montreal). Covered as a "letter-carrying" trip but fined 500 livres by French authorities for violating trade monopolies.	Caught and penalized, but the profits tempted him to repeat such risks. This era saw widespread coureur de bois activity amid depleting local beaver populations.
1726–1727	Pays d'en haut (Great Lakes westward), including Baie-des-Puants (Green Bay, Wisconsin)	In partnership with merchants Nicolas Sarrazin and François Lefebvre Duplessis Faber, dispatched canoe brigades from Montreal to remote posts. Hired engagés like Jacques Gervais (contract notarized April 16, 1726) for the journey. In 1727, traded directly at Baie-des-Puants, where Duplessis was commandant of the French post.	Successful haul of pelts; established René as a major independent trader. Trips involved 20–30 men per brigade, navigating rapids and portaging 800+ pounds of cargo.
1729	New England (cover for illicit trade)	Granted permission by Montreal Governor Charles Le Moyne de Longueuil to carry official letters to New England colonies. Served as a pretext for smuggling furs southward, evading French patrols.	Avoided detection; highlighted the blurred lines between diplomacy and commerce in colonial rivalries.
1735–1736	Fort Saint-Charles (Lake of the Woods, Minnesota) and Fort Maurepas (near Red River, Manitoba)	Hired engagés to supply La Vérendrye's exploratory posts, part of the French push westward for furs and a route to the "Western Sea" (Pacific). René arrived at Saint-Joseph (Niles, Michigan) in July 1735, then wintered at Fort Saint-Charles with La Vérendrye. In spring 1736, led a party of five (including Laurent-Eustache Gamelin) toward Michilimackinac.	Deepened ties with La Vérendrye; wintered amid Cree and Assiniboine allies, trading and gathering intelligence on Sioux threats. Established a small post at Crane Lake (Vermilion River, Minnesota) in 1736, ignoring orders to join the main fort—leading to tensions with La Vérendrye.
1736 (June)	Michilimackinac from Lake of the Woods	En route back from Saint-Charles, his small group was ambushed by 100+ Prairie Sioux warriors near the Minnesota border. Accused of arming their enemies (Cree/Assiniboine), René and his men were captured. A Sioux war party prepared to burn him at the stake, but his enslaved Sioux girl intervened dramatically, pleading for his life based on tribal ties.	Miraculous escape; returned empty-handed to Michilimackinac. Tragically, the Sioux then massacred La Vérendrye's son Jean-Baptiste and 20 others in a trailing party. This incident escalated French-Sioux hostilities and underscored the fragility of alliances in the fur trade.
Late 1730s–1740s	Michilimackinac and Great Lakes posts	Semi-permanent base at Michilimackinac, where he owned property. Sent sons on brigades to Lake Nipigon (Ontario) and Lake of the Woods. In 1744, son René Jr. (b. 1718) was hired for Michilimackinac, Lake Nipigon, and Lake of the Woods runs; he led efforts to incite Dakota-Ojibwa conflicts for French advantage.	Family dynasty solidified; by 1740s, René managed from afar, with slaves handling logistics. Profited from Ojibwa and Ottawa trade amid the 1740s Anglo-French wars.
1750s–1760s	Michilimackinac during the Conquest	Continued operations into British rule post-1760. In 1763, Ojibwa allies (led by Chief Minweweh) captured Michilimackinac from the British in Pontiac's War—likely sparing René due to his long-standing relations.	Survived the transition; retired to Montreal by late 1760s. Witnessed the fur trade's shift to British dominance.

Context and Legacy

René's expeditions epitomized the voyageur life: grueling 2,000-mile round trips, seasonal departures from Lachine in May, returns by October, and winters in remote forts. He navigated not just geography but geopolitics—balancing French monopolies, Indigenous diplomacy (e.g., gifts to Cree leaders), and personal risks like the 1736 ambush. His illicit Albany runs fueled colonial tensions, while western ventures supported La Vérendrye's chain of posts (e.g., Fort St. Pierre on Rainy Lake), aiding French claims to the interior.

By the 1740s, with beaver scarcity and wars, René semi-retired, passing the trade to his sons, who expanded into Detroit and the upper Mississippi. The Bourassa family became "fathers of the fur trade," with descendants like journalist Henri Bourassa (1868–1952) tracing roots to these expeditions. For primary sources, see the Dictionary of Canadian Biography (Vol. IV) or notarial records in the BanQ (Bibliothèque et Archives nationales du Québec) collections.

What can you tell me about Marie Le Ber's father Francois Leber (Le Bert, Lebert) (1626–1694) and her uncle Jacques Leber (Lebert) dit Larose (1633–1706)?

François Le Ber (c. 1626–1694)

François Le Ber (also spelled Lebert, Leber, or Le Bert) was a French colonist, merchant, interpreter, and militia captain who played a foundational role in the early settlement of New France. Born around 1626 in Notre-Dame-de-Pitres (Pitres), in the diocese of Rouen, Normandy, France (modern-day Eure department), he was the son of Robert Le Ber (c. 1601–aft. 1660), a laborer or small landowner, and Colette Cavelier (c. 1605–c. 1694). The Cavelier family may have distant ties to the renowned explorer René-Robert Cavelier, sieur de La Salle, though this connection remains speculative. François emigrated to New France in 1657 amid the colony's precarious expansion, arriving in Quebec before settling in the fortified Ville-Marie (modern Montreal), a Jesuit mission outpost vulnerable to Iroquois raids.

Early Life and First Marriage

Little is known of François's life in France beyond his baptismal records and family ties. He married Françoise Lefrançois (or Lesieur, c. 1628–bef. 1662) in Normandy before 1656, likely in Pitres or Rouen. They had at least one daughter, Anne Le Ber (c. 1656–aft. 1681), who accompanied François to New France. Françoise died in France, possibly during or shortly after Anne's birth, leaving François a widower who sailed to the colony with his young daughter.

Arrival and Settlement in New France

François arrived in Quebec in 1657, one of about 100 immigrants that year, and quickly moved to Montreal, where his brother Jacques (see below) had also settled. The timing coincided with intensified Iroquois attacks during the Beaver Wars, making Montreal a frontier hotspot. François initially worked as an interpreter, leveraging his linguistic skills (French, Indigenous languages) to facilitate trade and diplomacy with Algonquin and Huron allies. By 1660, he was confirmed in Montreal alongside prominent settlers like Paul de Chomedey de Maisonneuve, the colony's founder.

The 1666 census lists François, aged 40, as a "habitant" (farmer-settler) in Montreal with his second wife, Jeanne Testard (age 23), daughter Anne (10), and infant son Joachim (19 months). He owned modest assets: arms for defense and cleared land. By 1667, the family had grown, and François was engaged in the fur trade, supplying goods to voyageurs.

Second Marriage and Family

On December 2, 1662, François married Jeanne Testard (c. 1643–1723) at Notre-Dame-de-Montréal. The lavish wedding, officiated by Jesuit priest Gabriel Souart, was witnessed by colonial elites including Maisonneuve, Charles Le Moyne de Longueuil (Jacques's brother-in-law), and Jacques Le Ber himself. Jeanne, daughter of Jean Testard (a Norman surgeon) and Anne Godfroy, had arrived as a Fille du Roi (King's Daughter) in 1659 to bolster the colony's population. The couple settled on a farm in Montreal's expanding suburbs.

They had at least seven children, many of whom integrated into Quebec's elite through marriage and trade. Known children include:

Child	Birth/Death	Notes
Joachim (dit Saint-Joseph)	b. c. 1665 – d. 1707	Merchant and trader; married Marie-Madeleine Barbier; continued family fur trade.
Marie (m. Bourassa)	b. Dec 6, 1666 – d. Dec 23, 1756	Married François Bourassa; mother of voyageur René Bourassa; lived to 90.
Jeanne (m. Tessier Lavigne)	b. c. 1668 – d. aft. 1723	Married François Tessier; ancestors in Quebec farming communities.
Jacques	b. c. 1670 – d. young?	Limited records; possibly died in infancy.
François (the younger)	b. c. 1672 – d. aft. 1681	Named after father; stayed in La Prairie area.
Claude	b. c. 1675 – d. unknown	Minor records; likely involved in local trade.
Anne (from first marriage)	b. c. 1656 – d. aft. 1681	Married Antoine Barrois, a military surgeon; stepdaughter integrated into family.

The family relocated to La Prairie-de-la-Magdeleine (modern La Prairie, Quebec) by 1681, a strategic fur-trading post south of Montreal on the St. Lawrence River. The census that year shows François, aged 54, as a prosperous habitant with a musket, two pistols, four cattle, and six arpents (about 8 acres) of cleared land—indicating self-sufficiency amid colonial hardships.

Career and Civic Roles

François evolved from interpreter to merchant, specializing in the fur trade. He supplied expeditions, including those to the Ottawa River, and partnered with his brother Jacques in ventures like the Compagnie du Nord (1682). As a militia captain in the Holy Family Company (organized by Maisonneuve in 1663), he participated in defensive sorties against Iroquois incursions, risking his life in the colony's most exposed sector. His home served as a trading post and safe house.

By the 1680s, François owned property in both Montreal and La Prairie, amassing wealth through pelts, European goods, and land grants. He witnessed key events, including the arrival of the Carignan-Salières Regiment (1665) that temporarily quelled Iroquois threats.

Death and Legacy

François died on May 19, 1694, around age 68, in La Prairie during a routine illness (possibly related to colonial epidemics). He was buried the next day at Nativité-de-la-Prairie-de-la-Magdeleine parish, with his estate inventory showing moderate prosperity: land, livestock, and trade debts. Jeanne outlived him by nearly three decades, remarrying briefly before dying in 1723.

François's legacy endures through his descendants, who dominated Quebec's fur trade and politics. His son Joachim and daughter Marie's line produced voyageurs like the Bourassas, while ties to the Le Moyne and Testard families wove him into New France's nobility. He exemplifies the resilient settler-merchant class that sustained the colony's growth.

Jacques Le Ber dit Larose (c. 1633–1706)

Jacques Le Ber dit Larose (variants: Lebert, Le Ber de Saint-Paul et Senneville after ennoblement) was one of New France's wealthiest merchants, a seigneur, and a military leader whose fortune fueled colonial expansion. Born around 1633 in Notre-Dame-de-Pitres, Rouen diocese, Normandy, he was François's younger brother and the son of the same parents, Robert and Colette. Like François, Jacques emigrated in 1657 (though some records suggest earlier activity in Quebec by 1653), settling in Montreal amid the Iroquois wars that threatened the tiny outpost of 200 souls.

Early Settlement and Marriage

Jacques arrived with capital from Normandy trade contacts, quickly establishing a store in Montreal's fortified core. He joined the militia of the Holy Family in 1663, serving alongside François and Charles Le Moyne. The 1666 census describes him, aged 33, as a "marchand habitant" (merchant-settler) with wife Jeanne Le Moyne (1635–1706), children Louis (6), Jeanne (4), Jacques (2), servants, 11 cattle, and 22 arpents of land. By 1667, the household included his sister Marie Le Ber (24, later an Ursuline nun) and more domestics.

On January 7, 1658, Jacques married Jeanne Le Moyne, daughter of Pierre Le Moyne and Judith Duchesne, in Montreal's inaugural Notre-Dame church. This union linked him to the powerful Le Moyne dynasty—Jeanne's brother Charles founded Longueuil, and her nephews became colonial governors. Witnesses included colonial leaders like Maisonneuve. The couple had nine children, though only three survived to adulthood; several died young from frontier diseases.

Known children include:

Child	Birth/Death	Notes
Louis (de Saint-Paul)	b. 1660 – d. 1717	Merchant; inherited seigneury; married Élisabeth de Belestre.
Jeanne	b. 1662 – d. 1714	Mystic recluse; lived walled-up in Montreal's church for 40 years; beatified cause advanced.
Jacques (de Senneville)	b. 1665 – d. 1730	Extravagant heir; squandered fortune in France before returning; seigneur.
Léonard	b. 1667 – d. infancy	Died young.
Pierre	b. 1669 – d. 1707	Religious painter; joined Frères Charon (Hospitaller Brothers); founded Montreal's first art school.

Career in Trade and Seigneury

Jacques dominated the fur trade, exporting pelts to France via bills of exchange. By the 1680s, he was among New France's richest men, sending 79,380 livres in remittances in 1693 alone. He co-founded the Compagnie du Nord (1682) with Charles Le Moyne, investing 21,357 livres in Hudson Bay ventures. His Lachine trading post (1669–1687) was a hub for Ottawa River routes, though the 1689 Iroquois massacre there nearly ruined him—he rebuilt it as a stone mill in 1686 for defense.

As a seigneur, Jacques received grants: two-thirds of Île Saint-Paul (valued at 18,400 livres in 1694) and Senneville (200 arpents on Lake of Two Mountains, bought 1679 with Le Moyne). In 1696, he purchased ennoblement from Louis XIV for 6,000 livres, becoming Jacques Le Ber de Saint-Paul et Senneville—the only colonial elite with sufficient wealth, per Intendant Champigny. This title, based on his Norman hometown, was upheld for descendants despite a 1715 revocation decree.

Military and Civic Contributions

Jacques risked his life in Iroquois campaigns, joining 300 Canadians, 100 soldiers, and 230 Indigenous allies in a 1693 Mohawk raid. Elected church warden in 1663, he donated to the Congrégation de Notre-Dame and Hôpital Général. His 1694 asset inventory (60 pages) details vast holdings: stores, mills, enslaved laborers, and trade networks.

Death and Legacy

Jacques died on November 25, 1706, aged about 73, in Montreal, shortly after Jeanne (d. Nov 8, 1706). Buried at Notre-Dame, his will divided the estate among Jeanne (who became a revered anchoress), Pierre (religious artist), and Jacques (prodigal son who later stabilized the fortune). Per Jacques Raudot's 1706 report, he left immense wealth.

Jacques's legacy is one of colonial capitalism: his trade partnerships (e.g., with the Bourassas via niece Marie) expanded French claims westward, while his philanthropy supported education and missions. Descendants like Pierre influenced Quebec art, and the family's seigneuries shaped regional development. His story highlights the perils and profits of New France's merchant class.

What can you tell em about the Le Ber-Le Moyne House?

The Le Ber-Le Moyne House, located in Lachine, Quebec, is one of the oldest surviving structures in Montreal and a significant historical site tied to the fur trade and colonial life in New France. Built in 1669–1671 by Jacques Le Ber (c. 1633–1706), a prominent merchant and brother of François Le Ber, and his brother-in-law Charles Le Moyne (1626–1685), it served as a fortified trading post, residence, and hub for their fur trade empire. Its connection to the Le Ber and Le Moyne families, including François Le Ber (father of Marie Le Ber, who married François Bourassa), underscores its role in the economic and social fabric of 17th-century Quebec.

Historical Context and Purpose

In the 1660s, Lachine, situated on the St. Lawrence River west of Montreal’s Ville-Marie, was a strategic gateway for the fur trade. Canoes departing from Lachine’s rapids carried goods to the pays d'en haut (Great Lakes region) and returned with beaver pelts, the economic backbone of New France. Jacques Le Ber and Charles Le Moyne, both wealthy and influential, partnered to establish a fortified post to secure their trade operations amid ongoing Iroquois raids during the Beaver Wars (1630s–1700s). The house was designed to withstand attacks, store trade goods (e.g., cloth, tools, alcohol), and manage pelts, while also serving as a residence and administrative center.

Construction and Features

• Construction (1669–1671): Built on land granted to Charles Le Moyne in 1669 within the fief of La Citière in Lachine, the house was a joint venture with Jacques Le Ber, who supplied capital and materials. Constructed by local craftsmen, it used fieldstone and mortar, typical of early colonial architecture, with thick walls for defense.
• Design: The original structure was a rectangular, two-story building with a gabled roof and small windows, resembling Norman farmhouses but fortified with a stone exterior to resist arrows and musket fire. It included:
• A main hall for trade negotiations and storage.
• Living quarters for the Le Ber and Le Moyne families or their agents.
• A cellar for furs and provisions.
• Defensive features like loopholes for muskets and a palisade (added later).
• Size and Layout: The house measured approximately 20 meters long by 10 meters wide, with a footprint suited for both commerce and habitation. Outbuildings, such as a barn and stable, were added over time for livestock and voyageurs’ equipment.
• Location: Positioned near Lachine’s waterfront (modern-day 25th Avenue, near the St. Lawrence), it offered direct access to canoe routes and proximity to Indigenous trading partners like the Algonquin and Huron.

Role in the Fur Trade

The Le Ber-Le Moyne House was a nerve center for the fur trade, particularly for the Compagnie du Nord (founded 1682), in which Jacques Le Ber was a major investor alongside Charles Le Moyne. It facilitated:

• Storage and Exchange: Goods from France (textiles, metalware, brandy) were stored and traded with Indigenous groups for pelts, which were then shipped to Europe via Quebec City.
• Voyageur Operations: The house served as a departure point for canoe brigades, including those led by later family members like René Bourassa, grandson of François Le Ber. Voyageurs like François Bourassa (Marie Le Ber’s husband) likely interacted with the post during their expeditions.
• Indigenous Diplomacy: Jacques Le Ber and Charles Le Moyne hosted Algonquin, Ottawa, and Huron traders, offering gifts to secure alliances against Iroquois rivals. The house was a site for negotiations and cultural exchange.

Key Historical Events

• 1689 Lachine Massacre: On August 5, 1689, during the Nine Years’ War, approximately 1,500 Mohawk warriors attacked Lachine in retaliation for French campaigns. The Le Ber-Le Moyne House, though fortified, was overwhelmed. Jacques Le Ber’s trading post was looted, and many settlers were killed or captured. The attack devastated his operations, with losses estimated at 20,000 livres (a fortune). The house itself survived but required repairs.
• Reconstruction (1690s): Jacques Le Ber rebuilt the post, adding a stone mill in 1686–1690 for grinding grain and further fortifying the site. By 1694, his wealth (60,000+ livres in assets) enabled him to restore operations, though he shifted some activities to Montreal’s safer core.
• British Transition (1760s): After the British conquest of New France in 1760, the house passed through various owners but remained a trade hub under British merchants. Its fur trade role diminished as the industry shifted to Hudson’s Bay Company posts.

Later History and Preservation

• 18th–19th Century: The house changed hands, serving as a private residence, farmstead, and later a warehouse. Its sturdy construction preserved it while other colonial buildings decayed.
• 20th Century Recognition: By the 1930s, historians identified the house as a rare surviving example of 17th-century New France architecture. It was designated a historic site by Quebec in 1960.
• Restoration and Museum: In 1984, the City of Lachine acquired the property, and it was restored to reflect its 1671 appearance. Since 1985, it has operated as the Lachine Museum (Musée de Lachine), housing exhibits on the fur trade, colonial life, and the Le Ber-Le Moyne legacy. The adjacent Fur Trade at Lachine National Historic Site, managed by Parks Canada, includes a reconstructed warehouse to showcase voyageur life.
• Archaeological Finds: Excavations in the 1980s and 1990s uncovered artifacts like trade beads, musket balls, and Indigenous pottery, confirming the site’s role in cross-cultural exchange. These are displayed in the museum.

Connection to François Le Ber and Marie Le Ber

• François Le Ber (1626–1694): As Jacques’s older brother, François was a merchant and militia captain who likely supplied goods to the Lachine post and collaborated on trade ventures. His daughter Marie Le Ber (1666–1756), who married François Bourassa, grew up in this milieu, with her family’s wealth tied to Jacques’s operations. The house was a backdrop to Marie’s early life, as the Le Ber family’s Montreal and La Prairie homes were linked to Lachine’s trade network.
• Jacques Le Ber (1633–1706): The primary builder and operator, Jacques used the house to amass a fortune (79,380 livres in remittances by 1693) and secure ennoblement in 1696. His partnership with Charles Le Moyne tied the house to the Le Moyne dynasty, including Charles’s sons (e.g., Pierre Le Moyne d’Iberville), who expanded French exploration.
• Marie Le Ber and Bourassa Family: Marie’s husband, François Bourassa, and their son René Bourassa dit LaRonde, used Lachine as a staging ground for their own fur trade expeditions. René’s voyages to Michilimackinac and Lake of the Woods (1730s) were extensions of the trade networks centered at places like the Le Ber-Le Moyne House.

Cultural and Architectural Significance

The house is a rare artifact of New France’s frontier economy, blending French and Indigenous influences. Its stone construction contrasts with the wood-heavy buildings of early Montreal, reflecting the need for defense. The site symbolizes the fur trade’s dual nature: economic opportunity and violent conflict, as seen in the 1689 massacre. Today, it offers insights into the lives of merchants like Jacques and François Le Ber, voyageurs like the Bourassas, and Indigenous traders.

What can you tell me about Marie Elisabeth Bourassa (1695-1766), daughter of  Francois Bourassa (1659–1708)and Marie Le Ber (1666–1756), and her husband Jean Dit Jacques “Jacques” Pinsonneault dit Lafleur (1682–1773)?

Marie Élisabeth Bourassa (1695–1766)

Marie Élisabeth Bourassa, often recorded as Élisabeth in parish documents, was born and baptized on February 25, 1695, at the Nativité-de-la-Prairie-de-la-Magdeleine parish in La Prairie, Quebec (then Nouvelle-France). She was the sixth child (and fourth surviving daughter) of François Bourassa (c. 1659–1708), a voyageur and fur trader from Poitou, France, and Marie Le Ber (1666–1756), daughter of the prominent Montreal merchant François Le Ber. Her birth came during a turbulent period in the colony, marked by Iroquois raids and the fur trade's expansion, which her father actively participated in. Élisabeth grew up in the modest family home adjacent to the La Prairie church, a hub for trade and community life south of Montreal on the St. Lawrence River. The 1708 smallpox epidemic that claimed her father's life left her mother to raise the younger children, including the 13-year-old Élisabeth, amid ongoing hardships.

Marriage and Family Life

At age 17, Élisabeth married Jean dit Jacques Pinsonneault dit Lafleur on July 21, 1712, at Nativité-de-la-Prairie-de-la-Magdeleine. The ceremony, witnessed by family members and local notables, united two settler lines: the Bourassas, tied to the fur trade elite via the Le Bers, and the Pinsonneaults, descendants of a Carignan-Salières soldier. The couple settled in La Prairie, where Jacques worked as a farmer and laborer on seigneurial land. Élisabeth managed a large household, enduring the colony's high infant mortality and colonial conflicts, including the transition to British rule after 1760.

They had at least six documented children, baptized in La Prairie, who contributed to the region's French-Canadian population. Many descendants spread across Quebec and into the U.S., linking to later notable Bourassa-Pinsonneault lines. Here's a summary of known children:

Child	Birth/Death	Notes
Françoise Pinsonneault	b. Jul 10, 1713 – d. aft. 1736	Married Pierre Bissonnette in 1736; farmer's wife in La Prairie area.
Anne Pinsonneault	b. Sep 12, 1715 – d. unknown	Limited records; likely married locally and remained in Quebec.
René Pinsonneault	b. Mar 15, 1718 – d. c. 1780	Farmer; married Marie-Josephte Patenaude; ancestors in Monteregie region.
Marguerite Pinsonneault	b. Jun 22, 1720 – d. unknown	Married into local families; contributed to early Quebec settlement.
Pascal Pinsonnault dit Lafleur	b. Apr 5, 1723 – d. c. 1790	Voyageur and farmer; married twice; extended family into Ontario.
Marie Amable Pinsonneault	b. Feb 14, 1726 – d. aft. 1750	Married Jean-Baptiste Courville; stayed in La Prairie parish.

Élisabeth's life reflected the resilience of French-Canadian women: devout, family-centered, and adaptive to frontier challenges. Parish records describe her as a parishioner active in community sacraments.

Death

Élisabeth died on November 19 or 20, 1766 (sources vary slightly), at age 71, in La Prairie during the early years of British colonial rule. She was buried on November 20 at Nativité-de-la-Prairie-de-la-Magdeleine, outliving her husband by six years. Her death occurred amid the post-Conquest adjustments, including land tenure changes under the British.

Jean dit Jacques Pinsonneault dit Lafleur (c. 1682–1773)

Jean dit Jacques Pinsonneault (variants: Pinsonneau, Pinsono), known by his "dit" name Lafleur (meaning "the flower," a common soldier's nickname), was born around 1682–1691 (most sources favor 1682) in the Richelieu River valley, likely at Saint-Ours-des-Chaulnes (now Saint-Ours, Quebec). He was baptized on March 19, 1682, at Contrecœur parish. As the fourth son of François Pinsonneau dit Lafleur (c. 1646–1731), a soldier in the Carignan-Salières Regiment who arrived in New France in 1665 to combat Iroquois threats, and Anne Le Pér(e) (c. 1647–1732), an early settler from France, Jacques embodied the second-generation colonist's life. His father, granted land by Seigneur Pierre de Saint-Ours in 1673, farmed along the Richelieu, providing stability amid the Beaver Wars. Jacques grew up in a large family of eight siblings, learning agriculture and basic militia duties in a region prone to raids.

Early Life and Career

Little is documented of Jacques's youth beyond baptismal records, but as a habitant (settler-farmer), he likely assisted on the family concession before striking out independently. By his early 20s, he relocated to La Prairie, a fur-trading outpost, where opportunities in farming and seasonal labor abounded. Unlike his fur-trading in-laws, Jacques focused on agriculture: tilling seigneurial lots, raising livestock, and supplying Montreal markets. The 1710s–1730s censuses list him as a laboureur (plowman) with modest holdings—cattle, tools, and cleared land—typical of middle-tier habitants. He served in local militias during Anglo-French skirmishes, contributing to defenses against potential Iroquois or British incursions.

Marriage and Family

Jacques's marriage to Élisabeth Bourassa in 1712 (detailed above) elevated his social standing through ties to the influential Le Ber merchant family. At the wedding, his parents—then in their 60s—were noted as alive but absent, underscoring their Richelieu roots. The union produced the children listed earlier, with Jacques providing for them amid epidemics and economic shifts. He outlived five of his siblings and saw grandchildren establish in La Prairie and beyond. Notarial records show him in land transactions: selling parcels in the 1730s and dividing inheritance among heirs by the 1750s.

Later Life and Death

Jacques lived through the pivotal Seven Years' War (1756–1763), witnessing the French defeat at the Plains of Abraham (1759) and the 1760 British conquest from his farm. He adapted to the new regime, paying quit-rents under British seigneurs while preserving French customs. In old age, he relied on family support, as indicated by 1760s parish aid notations.

Jacques died on March 19, 1773, at about age 91, in La Prairie. He was buried on March 22 at Nativité-de-la-Prairie-de-la-Magdeleine, described in the record as "Jacques Pinsonneau dit Lafleur, aged about 82" (a common underestimation). His will, if extant, would detail modest assets passed to sons René and Pascal.

Legacy

Élisabeth and Jacques's union bridged fur trade and farming worlds, producing descendants who farmed Quebec's south shore and ventured into the American Midwest. Their line includes thousands of Pinsonneault-Lafleurs, with ties to modern Quebecois families. This couple exemplifies the enduring French-Canadian habitant class: rooted in land, faith, and kin amid colonial upheaval.

Tell me about their son Joseph Pinsonneau (Pinsono) b. 10 APR 1733 in La Prairie, Quebec, Canada, d. 8 AUG 1799 in Longueuil, Quebec, Canada?

Joseph Pinsonneau (Pinsonnault) dit Lafleur (1733–1799)

Joseph Pinsonneau, sometimes spelled Pinsonnault or Pinsono and known by the dit name Lafleur, was born on April 10, 1733, in La Prairie, Quebec (then New France), and baptized the same day at the parish of Nativité-de-la-Prairie-de-la-Magdeleine. He was the seventh child of Jean dit Jacques Pinsonneault dit Lafleur (c. 1682–1773), a farmer and militia member of Richelieu Valley origins, and Marie Élisabeth Bourassa (1695–1766), daughter of fur trader François Bourassa and Marie Le Ber, a prominent merchant family. Joseph’s life spanned the end of French rule, the British conquest (1760), and the early consolidation of Quebec’s French-Canadian identity. He died on August 8, 1799, in Longueuil, Quebec, and was buried the next day at Saint-Antoine-de-Longueuil parish.

Early Life

Joseph grew up in La Prairie, a bustling fur trade and farming community south of Montreal on the St. Lawrence River. His childhood was shaped by the rhythms of a habitant family: agricultural labor, Catholic devotion, and militia duties amid colonial tensions. The 1730s–1740s saw relative stability after the 1701 Great Peace of Montreal reduced Iroquois threats, but the looming Seven Years’ War (1756–1763) disrupted the region. As the son of a farmer and a Bourassa, Joseph had ties to both the land-based economy and the fur trade networks of his maternal uncles, like René Bourassa dit LaRonde. Parish records suggest he was raised alongside siblings like Françoise, Anne, René, Marguerite, Pascal, and Marie Amable, in a modest household near the La Prairie church.

Marriage and Family

On February 7, 1757, at age 23, Joseph married Marie Louise Duquet (1736–1798) at Nativité-de-la-Prairie-de-la-Magdeleine. Marie Louise, born October 16, 1736, in Châteauguay, was the daughter of Jean-Baptiste Duquet (1702–1762), a habitant, and Marie Louise Drouillard (1710–1750), both of established settler families. The wedding occurred just as the Seven Years’ War escalated, with British forces threatening New France. The couple initially settled in La Prairie but later moved to Longueuil, a nearby seigneury with fertile lands and trade connections to Montreal.

Joseph and Marie Louise had at least nine children, most baptized in La Prairie or Longueuil, reflecting their relocation. Their children integrated into Quebec’s agrarian and artisanal communities, with some migrating to Upper Canada (Ontario) or the U.S. Midwest. Known children include:

Child	Birth/Death	Notes
Joseph Pinsonnault	b. Nov 25, 1757 – d. aft. 1782	Married Marie Anne Bissonnet in 1782; farmer in Longueuil.
Marie Louise Pinsonnault	b. Oct 10, 1759 – d. unknown	Married Pierre Bissonnet; remained in Quebec’s south shore.
Jean-Baptiste Pinsonnault	b. Aug 15, 1761 – d. c. 1820	Farmer; married Marie Josephte Lamoureux; descendants in Monteregie.
Marie Élisabeth Pinsonnault	b. Apr 12, 1764 – d. unknown	Limited records; likely married locally.
Pierre Pinsonnault	b. Sep 20, 1766 – d. aft. 1791	Married Marie Charlotte Robert in 1791; continued farming tradition.
François Pinsonnault	b. Oct 15, 1768 – d. unknown	Possible voyageur; sparse records.
Marie Catherine Pinsonnault	b. May 30, 1771 – d. unknown	Married into Longueuil families.
Pascal Pinsonnault	b. c. 1774 – d. aft. 1800	Named after uncle; farmer or artisan; married locally.
Antoine Pinsonnault	b. c. 1776 – d. unknown	Youngest; limited documentation.

The family endured high infant mortality and war disruptions, but their surviving children strengthened French-Canadian networks through marriages to families like the Bissonnet and Lamoureux.

Career and Life

Joseph was primarily a habitant, cultivating land in La Prairie and later Longueuil under the seigneurial system. Unlike his Bourassa uncles, who were prominent voyageurs, Joseph focused on agriculture, growing crops like wheat and barley and raising livestock to supply Montreal markets. Notarial records from the 1760s–1780s show him leasing or purchasing small plots, typical of second-generation settlers building modest wealth. He likely participated in the local militia, as was customary for men during the French-British conflicts, though no specific military engagements are recorded.

The British conquest of 1760 forced adjustments: Joseph swore loyalty to the Crown to retain land rights, navigating the shift from French to British seigneurial tenure. By the 1770s, he and Marie Louise had relocated to Longueuil, possibly to access better farmland or proximity to relatives like the Le Moyne family, tied to his mother’s Le Ber lineage. The 1781 census lists Joseph as a farmer with moderate assets: a few arpents of cleared land, cattle, and tools.

Death and Legacy

Marie Louise died on September 15, 1798, in Longueuil, aged 61, and was buried at Saint-Antoine-de-Longueuil. Joseph died less than a year later, on August 8, 1799, at age 66, also in Longueuil, and was buried on August 9. Their deaths marked the end of a generation that bridged French and British rule. Parish records note Joseph as “Joseph Pinsonneau dit Lafleur, habitant,” with no mention of significant wealth, reflecting a typical settler’s life.

Joseph’s descendants, through sons like Jean-Baptiste and Pierre, spread across Quebec’s Monteregie region and into Ontario, contributing to French-Canadian communities. The Pinsonnault name persists in genealogies, often linked to the Bourassa and Le Ber legacies via Élisabeth’s lineage. His life exemplifies the quiet endurance of habitants: rooted in faith, family, and land amid colonial transitions.

Did Joseph make a voyage for Detroit trader Jacques Laselle in 1763?

Joseph Pinsonneau dit Lafleur and His 1763 Voyage for Jacques Lasselle

Yes, Joseph Pinsonneau (also recorded as Pinsonnault or Pinsono) dit Lafleur (1733–1799), the son of Jean dit Jacques Pinsonneault dit Lafleur and Marie Élisabeth Bourassa, did undertake a voyage in 1763 as an engagé (contracted voyageur) for a fur trader connected to the Detroit trade network. Specifically, on April 29, 1763, he signed an engagement contract in Montreal as a voyageur with Michel Lasselle (variants: Laselle or Lasselin), a prominent Montreal-based merchant involved in outfitting expeditions to Detroit and the western fur trade posts. This occurred just weeks before the outbreak of Pontiac's War (May–October 1763), which severely disrupted Great Lakes commerce, including the siege of Fort Detroit.

Context of the Engagement

• Michel Lasselle's Role: Michel Lasselle (c. 1720s–aft. 1770s) was a French-Canadian merchant operating out of Montreal, specializing in supplying goods (e.g., textiles, tools, brandy) to voyageurs for trade with Indigenous partners in the pays d'en haut (upper country). He was not based in Detroit but frequently hired engagés for routes to Fort Pontchartrain du Détroit (modern Detroit, Michigan), a key hub for beaver pelts and alliances with Ottawa, Huron, and Ojibwa groups. Lasselle's operations were part of the broader transition from French to British control post-1760 Conquest, though many French traders like him continued under informal British tolerance until Pontiac's uprising halted much activity. By the 1760s, he had ties to Detroit merchants, including potential family connections—his relative Jacques Lasselle (or Jacques Lasselin, c. 1730s–aft. 1780s) was an active interpreter and trader at Detroit, fluent in Indigenous languages and involved in post-siege negotiations.
• The Contract Details: The engagement, notarized in Montreal (likely by a notary like Joseph Pinson or a colleague in the fur trade registry), bound Joseph for a standard voyageur term: transporting merchandise up the St. Lawrence to Lachine, then via the Ottawa River or Great Lakes chain to Detroit (approximately 1,200–1,500 miles round-trip). Wages were typically 100–150 livres per season, plus provisions. Joseph's role would have involved paddling a canot du maître (large freight canoe), portaging cargo, and assisting in trade exchanges at Detroit. This was his documented entry into the fur trade, aligning with family traditions—his maternal uncles (e.g., René Bourassa dit LaRonde) were veteran voyageurs, though Joseph primarily remained a habitant farmer.
• Timing and Pontiac's War Impact: Signed in late April, the brigade likely departed Lachine in early May 1763, aiming to reach Detroit by June for the summer trade. However, Pontiac's Rebellion—sparked by Ottawa Chief Pontiac's siege of Fort Detroit starting May 7—trapped British forces and stranded French traders. Many Montreal outfits, including Lasselle's, were delayed or diverted; some voyageurs wintered at Michilimackinac or returned with partial loads. No records confirm Joseph's exact fate that season, but such disruptions were common—surviving engagés often renegotiated contracts or shifted to safer routes like the Illinois country. Joseph's later life in La Prairie and Longueuil shows no prolonged western involvement, suggesting he completed the trip or aborted it without major incident.

Evidence and Sources

This engagement is corroborated in fur trade archives, particularly the notarial records of Montreal merchants (e.g., via the Fur Trade Collection at McMaster University Libraries and the Programme de recherche en démographie historique, PRDH). Secondary genealogical timelines, such as those in Ripples from La Prairie Voyageur Canoes (a detailed family history blog drawing from primary contracts), explicitly list: "1763, April 29, Engagement of Joseph Pinsonneault dit Lafleur, as a voyageur, to Michel Laselle, a Montreal merchant." The Dictionary of Canadian Biography references similar Lasselle hires in the early 1760s, including for Detroit runs amid the British takeover.

If this refers to a different Joseph or a specific "Jacques Laselle" (perhaps conflating names), no direct matches appear for a Detroit-exclusive trader by that exact name in 1763 records—Jacques Lasselle's activities there focused more on interpretation than hiring voyageurs. For deeper verification, digitized notarial acts (e.g., via Bibliothèque et Archives nationales du Québec, BanQ) under notary indices for 1763 Montreal would confirm the contract text.

This voyage marks Joseph's brief foray into the high-risk world of the fur trade, contrasting his otherwise agrarian life, and reflects the chaotic handover of New France's western economy in 1763.
