What became of Sacagawea and her infant son?

Sacagawea and her infant son, Jean Baptiste Charbonneau, continued to be part of the Lewis and Clark Expedition, which concluded in 1806. After the journey, Sacagawea and her husband, Toussaint Charbonneau, settled in the Mandan village in present-day North Dakota. Later, she and her family moved to the Shoshone territory, where she lived until her death in 1812. Jean Baptiste went on to lead an adventurous life, eventually becoming a guide and fur trader.
