Who was sacagawea sold to?

Sacagawea was sold (or possibly won in a bet) to a French-Canadian fur trader named Toussaint Charbonneau. Historical information as to when Charbonneau took Sacagawea as his wife is sketchy and sometimes inconsistent. The Lewis and Clark journals specifically refer to Sacagawea as Charbonneau's wife in an entry dated November 4, 1804.
