In the American Fort Mandan on February 11, 1805, Sacagawea gave birth to her son Jean-Baptiste Charbonneau.

Eight months after her death, Clark legally adopted Sacagawea’s two children, Jean Baptiste and Lisette.

Jean Baptiste was educated by Clark in St. Louis, and then, at age 18, was sent to Europe with a German prince.

Jean Baptiste lived for six years as a member of the royal household, receiving a classical education in Germany.

Jean Baptiste returned to Missouri in 1829, worked as a trapper in Idaho and Utah, traveled with Jim Bridger, Jim Beckwourth, and Joe Meek, and was a guide for the Mormon Battalion from Santa Fe to San Diego in 1846 during the War with Mexico. He was briefly the Alcalde (mayor) of Mission San Luis Rey in California, and spent many years in the gold fields on the American River near Sacramento.

He was listed as a clerk in the Orleans Hotel in Auburn, California by 1861. He headed for the newly opened Montana goldfields in 1866, but died of pneumonia while traveling on May 16 of that year in Inskip Station, Oregon. He is buried there today. The site is located in Danner, Oregon, 3 miles north of Interstate Route 95.

Thérèse (DesLauriers) LaPolice claims that her grandmother, EMMA CHARBONNEAU, was decended from this line. This has yet to be proved.
