Siouan languages
Siouan or Siouan–Catawban is a language family of North America that is located primarily in the Great Plains, Ohio and Mississippi valleys and southeastern North America with a few other languages in the east.
Protohistory of West Virginia
Linguistic and historical records indicate a possible southern origin of Siouan peoples, with migrations over a thousand years ago from North Carolina and Virginia to Ohio. Some peoples continued down the Ohio River to the Mississippi River and up the Missouri River, and others across Ohio to Illinois, Wisconsin and Minnesota, home of the Dakota. Ohio Valley Siouan (Southeastern Siouan) is a group of related Siouan languages, which included the Ofo language, Biloxi language, and the Tutelo language. The Tutelo language was a group of mutually intelligible dialects spoken by the Tutelo, Monacan, Manahoac and Nahyssan confederacies, and Occaneechi in what is now Virginia and West Virginia.
