Did you know that Billy Caldwell and Sauganash are two names for the same person? A chief of the Potawatomi, he was half-British, half-Native American man who interceded to save white families in the aftermath of the Battle of Fort Dearborn in 1812. Sauganash was held in such esteem that the government granted him 1,600 acres of land on the North Branch of the Chicago River, an area that includes Sauganash,Forest Glen and South Edgebrook.
