In the mist-shrouded ports of 17th-century Normandy, where the Seine River whispered secrets of distant horizons, the threads of our ancestry began to intertwine with the grand saga of New France. Rouen, a bustling hub of merchants and mariners, cradled the early lives of our 9th great-grandparents, Robert LeBer (born around 1601) and Colette Cavelier (1605–1694). Robert, a man of modest means—perhaps a tradesman or laborer in the shadow of Rouen's Gothic cathedral—married Colette around 1620. Their union produced at least three children who would bridge the Old World and the New: Marie (1620–1714), who later became an Ursuline nun in Quebec; Francois (1626–1694), our direct 8th great-grandfather; and Jacques (1633–1706), whose marriage would forge an alliance with one of Canada's most storied families. Though some records cloud Robert's death (likely after 1633, possibly as late as 1676), his legacy endured through his offspring's bold migration across the Atlantic, drawn by tales of untamed wilderness and opportunity in the fledgling colony of Ville-Marie (now Montreal).
Francois and Jacques Leber arrived in New France around 1657–1658, embodying the hardy spirit of the habitants—settler-farmers who tamed the land amid Iroquois raids and harsh winters. Francois, a voyageur and fur trader, settled in La Prairie, a strategic outpost south of Montreal on the St. Lawrence River. This riverside village, founded in 1647 by Jesuits, became a cradle for our ancestors, its fertile plains yielding crops while its waters carried canoes laden with beaver pelts to distant markets. In 1662, Francois married Jeanne Testard (1642–1723), a fille du roi (King's Daughter)—one of the brave women sponsored by Louis XIV to bolster the colony's population. Their life in La Prairie was one of resilience: farming arpents of land, defending against indigenous skirmishes, and raising a family that included our 7th great-grandmother, Marie Le Ber (1666–1756).
Meanwhile, Jacques Leber dit Larose—Francois's brother and our 8th great-granduncle—carved a path of prosperity in Montreal. A merchant and militia member of the Holy Family confraternity, he partnered in trade with the era's elite. On January 7, 1658, in Montreal's nascent Notre-Dame church, Jacques wed Jeanne Le Moyne (1635–1682), daughter of Pierre Le Moyne (1595–1658) and Judith Duchesne from Dieppe. This union was no mere match; it bound the humble Leber line to the aristocratic Le Moyne dynasty, whose exploits would echo through North American history.
Jeanne's brother, Charles Le Moyne de Longueuil et de Châteauguay (1626–1685), was a titan of New France. Born in Dieppe, he arrived in Canada at age 15 in 1641, mastering indigenous languages and rising from interpreter to seigneur. Granted lands in Longueuil and Châteauguay, he fortified Montreal against Iroquois attacks, amassing wealth through fur trade and military prowess. His marriage to Catherine Thierry Primot produced 14 children, many of whom became legends. As in-laws to our Leber ancestors, the Le Moynes infused our lineage with tales of valor: Jacques and Jeanne's home in Montreal hummed with visits from Charles's brood, where strategies for raids and trades were plotted over hearth fires.
Among Charles's sons—our 8th great-granduncle's nephews by marriage—shone Pierre Le Moyne d'Iberville (1661–1706), the swashbuckling explorer who harried English ships in Hudson Bay, raided Newfoundland, and founded Louisiana in 1699, planting French flags from Biloxi to Mobile. His brother Jean-Baptiste Le Moyne de Bienville (1680–1767) extended this legacy, establishing New Orleans in 1718 amid swamps teeming with alligators and promise. Charles II Le Moyne de Longueuil (1656–1729), the first native-born Canadian baron, served as governor of Montreal and Trois-Rivières, his childhood as a page in France honing him for command. François Le Moyne de Bienville (1666–1691) fell in battle against the Iroquois at Repentigny, a martyr to the colony's defense. Jacques Le Moyne de Sainte-Hélène (1659–1690), Paul Le Moyne de Maricourt (1663–1704), Joseph Le Moyne de Sérigny (1668–1734), and Antoine Le Moyne de Châteauguay (1671–1711) all fought in campaigns that secured French footholds, from Acadia to the Gulf of Mexico.
Jacques and Jeanne's own children added layers to this tapestry: Their daughter Jeanne Le Ber (1662–1714), a famed recluse and embroiderer, lived in ascetic devotion, her cell in Montreal's church inspiring calls for sainthood. Their son Pierre Le Ber (1669–1707), a painter, captured Marguerite Bourgeoys in portrait, preserving the era's piety.
Back in La Prairie, our direct line through Francois flourished amid this extended family's influence. Marie Le Ber married François Bourassa in 1681, their daughter Marie Elisabeth Bourassa (1695–1766) wedding Jacques Pinsonneau. The Pinsonneaus, rooted in La Prairie's agrarian life, navigated the British conquest after 1763, anglicizing names as they migrated. Joseph Pinsonneau (1733–1799), a DNA-matched ancestor, fathered Gabriel Pinsonneau (1770–1807), whose son Gabriel (Gilbert) Passino (1803–1877) adapted to borderlands life, crossing into New York or Vermont amid economic shifts. Gilbert's daughter, Lucy Passino (1836–1917), our 2nd great-grandmother, carried this resilient spirit forward—her world one of farms, factories, and frontier towns in a changing America.
From Rouen's cobblestones to La Prairie's riverbanks, and onward to my own life as A Drifting Cowboy, this story arcs across centuries. The Le Moynes' daring—forging empires from canoes and courage—echoes in our veins through fraternal bonds and marital ties. Though not direct blood, their legacy of exploration and endurance shaped the world our La Prairie forebears inhabited, a reminder that history's great currents often flow through quiet family streams.
Adventurers of The sons of Charles Le Moyne
The sons of Charles Le Moyne de Longueuil et de Châteauguay formed a remarkable dynasty in New France, with many achieving fame through military exploits, exploration, and colonial administration. Below, our 8th great-granduncle's nephews by marriage—focusing on the key places and events that made them noteworthy. We’ve drawn from historical biographies to ensure accuracy, highlighting their roles in French expansion, conflicts with the English and Indigenous nations, and the founding of settlements. Note that some dates (like Antoine's) vary slightly across sources due to incomplete 17th-century records, but We’ve aligned with the most consistent accounts.
Charles II Le Moyne de Longueuil (1656–1729)
As the eldest son and the first native-born Canadian to receive a barony in New France (granted in 1700), Charles II embodied the transition from frontier settler to colonial nobleman. His career emphasized governance and defense in the heart of New France.

Captured Nevis from the English in 1706 during Queen Anne's War. Died of yellow fever in Havana while planning attacks on the Carolinas.

François Le Moyne de Bienville (1666–1691)
The fifth son, François (known as Bienville I to distinguish from his younger brother) was a young officer whose brief career focused on frontier skirmishes.
- Key Places: Montreal (birthplace), Iroquois lands (New York and Quebec), Schenectady (New York), and Repentigny (Quebec, death site).

Killed in action on June 6, 1691, during a skirmish with Oneida warriors near Repentigny while pursuing raiders. His death exemplified the high cost of colonial warfare for the Le Moyne family.
Joseph Le Moyne de Sérigny (1668–1734)
Joseph was a naval officer who supported his brothers' ventures, blending military service with colonial entrepreneurship.

Antoine Le Moyne de Châteauguay (1671–1711, per our notes; sources often cite 1683/1687–1747)
Antoine (the youngest notable son in some accounts) assisted in Louisiana's early development, serving as a naval midshipman and colonial officer. (Note: Some records confuse him with brother Louis de Châteauguay [1676–1694], who died young in battle; W’eve focused on Antoine as listed.)
- Key Places: Montreal (birthplace), Louisiana (Mobile and lower Mississippi), France (naval service), and the Gulf Coast.
- Noteworthy Events: Served as a midshipman in the French navy from youth. Joined brothers Pierre and Jean-Baptiste in Louisiana expeditions (1700s), helping establish settlements like Mobile. Participated in early colonial administration and defenses against English and Spanish rivals. Inherited the Châteauguay seigneury; sources note his death around 1747 in France, but if aligning with our 1711 date, it may tie to early Gulf skirmishes.
These brothers' collective achievements—spanning from Arctic raids to Southern colonies—helped secure French influence in North America, directly impacting the world our La Prairie ancestors navigated.
