Sauganash

Billy Caldwell Jr., , baptized Thomas Caldwell (March 17, 1782 – September 28, 1841), known also as Sauganash (Zhaaganaash: [one who speaks] English), was a British-Potawatomi fur trader who was commissioned captain in the Indian Department of Canada during the War of 1812. He moved to the United States in 1818 and settled there. In 1829 and 1833 he negotiated treaties on behalf of the United Nations of Chippewa, Ottawa and Potawatomi with the United States, and became a leader of a Potawatomi band at Trader's Point (Iowa Territory). He worked to gain the boundary long promised by the British between white settlers and Indians, but never achieved it.

Born in a Mohawk refugee camp near Fort Niagara, Billy was the son of a Potawatomi mother (Misheswans) (Caldwell Oral Family History - Ontario) and William Caldwell, a Scots-Irish immigrant to North America and a Loyalist British officer during the American Revolutionary War. He became multilingual, learning Potawatomi, English, and French.

After moving to the United States in 1818, Caldwell became a fur trader and learned the Potawatomi language, an Algonquian language; he negotiated with numerous tribes in the Lake Michigan area. He gained their respect and also acted as a translator and negotiator between the government and American Indians. In 1829, Caldwell represented the Chippewa, Ottawa and Potawatomi peoples of the United Nations Tribes in negotiating the Second Treaty of Prairie du Chien with the United States. For his work, the US granted him a 1600-acre tract, known as the Caldwell Reserve, along the Chicago River. Eighty acres is included within the Cook County Forest Preserve.
