The Yuchi (Hughchee, Uchi), with the Westo, lived at rious times in several places in the southeastern United States, from eastern Tennessee to Florida, with three main bands, one on the Tennessee River, one in northwestern Florida, and one in the middle drainage of the Savannah River in Georgia. Some of their descendants live in the northwestern part of the former Creek Indian Reservation in eastern Oklahoma, although the Yuchi are extinct as a distinct culture unit. They spoke a language isolate in the Macro-Siouan phylum.
