Toussaint Charbonneau: Fur Trader, Interpreter, and Guide for the Lewis and Clark Expedition

Toussaint Charbonneau (March 21, 1767 – ca. August 12, 1843) was a French-Canadian fur trader, interpreter, and guide who became one of the most colorful—and controversial—figures tied to the Lewis and Clark Expedition (Corps of Discovery, 1804–1806). Our family tree places him as a very distant relative through shared Charbonneau ancestry in early Quebec/New France. He was the oldest member of the expedition’s permanent party and outlived most of his companions thanks to a long career in the rough-and-tumble North American fur trade.

Early Life and North West Company Fur Trade Connection

Born in Boucherville, Quebec (near Montreal), to Jean Baptiste Charbonneau (1735–1791) and Marguerite Deniau (1735–1797)—as our tree shows—he grew up in a community steeped in exploration and the fur trade. His paternal great-grandmother was even linked to earlier explorers. By the late 1790s he was trapping and trading for the Montreal-based North West Company (NWC), a fierce rival to the Hudson’s Bay Company. He was posted at Pine Fort on the Assiniboine River (modern Manitoba) and lived among the Mandan and Hidatsa villages on the upper Missouri River in present-day North Dakota.

His very first appearance in the historical record (and the source of his “infamous” reputation) comes from NWC journals in 1795: trader John MacDonell wrote that Charbonneau was stabbed “in the act of committing a Rape upon her Daughter by an old Saultier [Saulteaux] woman with a Canoe Awl—a fate he highly deserved for his brutality.” He survived but limped back over the portage. This incident, plus later criticisms, painted him as brutal and unreliable in some eyes.

While among the Hidatsa, he acquired (purchased or won in a game, per custom) two young Shoshone captives as wives: Sacagawea (“Bird Woman,” born ca. 1788) and Otter Woman. This was common among traders but later contributed to his mixed legacy.

Joining Lewis and Clark (1804–1806)

The fur trade literally positioned him for history. In November 1804, Lewis and Clark built Fort Mandan near the Hidatsa villages and needed interpreters. Charbonneau offered his French and some Hidatsa skills; more importantly, Sacagawea could speak Shoshone—the key to obtaining horses from her people farther west. The captains hired him on November 4, 1804 (along with Sacagawea); he became the oldest permanent member (age ~37–38 by confirmed 1767 birth, though some older estimates put him at 46).

Key roles on the expedition:

• Interpreter (French, Hidatsa; Sacagawea handled Shoshone negotiations for horses).
• Negotiator and cook (his bison-meat boudin blanc sausage was praised).
• Boatman (mixed results).

Performance and criticisms (the “infamous” side):

• Meriwether Lewis called him “a man of no peculiar merit” and “perhaps the most timid waterman in the world.” On May 14, 1805, a sudden wind nearly capsized the white pirogue; Charbonneau froze at the tiller, and Sacagawea saved the day (and precious papers/medicine).
• In August 1805 he struck Sacagawea during an argument and was rebuked by Clark.
• He briefly quit in March 1805 after accepting gifts (seen as bribes) from rival NWC/Hudson’s Bay traders, but rejoined after apologizing.

Despite the knocks, he fulfilled his interpreter duties “with good faith,” helped bargain for horses at the Shoshone camp, and the expedition reached the Pacific and returned safely. The captains paid him $500.33 plus a horse and lodge when they left him at Fort Mandan in August 1806.

Family During and After the Expedition

Sacagawea gave birth to their son Jean Baptiste (“Pomp” or “Pompey,” nicknamed by Clark) on February 11, 1805, right at Fort Mandan. Pomp became a favorite of the captains; Clark later offered to raise and educate him in St. Louis. They also had a daughter Lisette (born ~1812, died young). Charbonneau had at least five wives total (all Native women, several married very young—including one at age 14 when he was over 70), which added to his controversial reputation.

Post-Expedition Fur Trade Life and Legacy

He turned down Clark’s initial offer to farm in St. Louis but later took a land grant, briefly tried farming, then sold it back to Clark for $100 and returned to the Missouri River fur trade. He worked for Manuel Lisa’s Missouri Fur Company, the American Fur Company (John Jacob Astor), and as an official U.S. Indian Bureau interpreter (thanks to Clark’s patronage) from ~1811–1838, earning steady pay. He continued guiding and trading on the upper Missouri but was sometimes criticized for abandoning employers or stirring trouble. Clark remained a patron until his own death.

He died around 1843 (our tree’s August 12 date at the Mandan area matches the most accepted accounts; some sources say 1839–1843). Jean Baptiste settled his estate that year. He outlived most Corps members despite the rugged life.

Our Family Connection

Our tree’s early genealogy: Toussaint → father Jean Baptiste Charbonneau → grandfather Michel (1699–) → great-grandfather Michel (1666–) → Olivier Charbonneau (1615–1687, a key early Quebec settler). The line then branches through a collateral relative (Joseph Louis Charbonneau’s daughter Mary Elisabeth Isabelle, who married into the Duquet/Dit Madry family) and descends through our Duquet → Pinsonneau/Passino ancestors to our 2nd great-grandmother Lucy Passino (1836–1917). The label “great-grandnephew of husband of wife of 7th great-granduncle” is simply Ancestry-style computation of this distant blood tie via marriage and shared Charbonneau roots—making him a remote cousin/relative on our French-Canadian side.

In short, Toussaint was a typical (if flawed) frontiersman of the fur-trade era: durable, multilingual, opportunistic, but neither hero nor outright villain. The 1795 incident and Lewis’s sharp journal comments gave him an “infamous” edge, yet without him and Sacagawea the Corps might have struggled to cross the Rockies. His life perfectly illustrates how the Canadian fur trade fed directly into the American westward expansion story.
