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.
Monacan people
The contemporary Monacan people claim descent from the historic Monacan tribe, first recorded in 1607 in Virginia. They originally spoke a Siouan language and were related to other Siouan-speaking tribes, such as the Tutelo, Saponi and Occaneechi. Today the people speak English.
