Toussaint Charbonneau was a French Canadian who had been hired at Fort Mandan as a boatman and interpreter. This winter he was about 47 years old. His wife, Sacagawea, a Shoshone Indian who had been captured by Hidatsas about 1800 in the vicinity of the Three Forks of the Missouri, may have reached her 17th year.
Their son, Jean Baptiste, was born at Fort Mandan on February 11, 1805. If anyone acknowledged his first birthday here at Fort Clatsop, it is not mentioned in the surviving journals. That is not surprising, since ordinary folks back then seldom celebrated their birthdays.
