Sacagawea was born c. 1766 into an Agaidiku ("Salmon Eater") tribe of Lemhi Shoshone between Kenney Creek and Agency Creek about twenty minutes away from Hayden and Bear Trail Creeks in the city of Salmon in Lemhi County, Idaho. After the expedition, Sacagawea's husband Toussaint took a job with the Missouri Fur Company, and stayed at Fort Manuel Lisa in present-day North Dakota.
