Siouan languages
Siouan languages can be grouped into the Western Siouan languages and Catawban languages. The Western Siouan languages can be divided into Missouri River languages (such as Crow and Hidatsa), Mandan, Mississippi River languages (such as Dakotan, Chiwere-Winnebago, and Dhegihan languages), and Ohio Valley Siouan branches. The Catawban languages consist only of Catawban and Woccon.
Western Siouan languages
Linguistic and historical records indicate a possible southern origin of the Siouan people, with migrations over a thousand years ago from North Carolina and Virginia to Ohio. Some continued down the Ohio River to the Mississippi and up to the Missouri. Others went down the Mississippi, settling in what is now Alabama, Mississippi and Louisiana. Others traveled across Ohio to what is now Illinois, Wisconsin, and Minnesota, home of the Dakota.
