Siouan languages
Authors who call the entire family "Siouan" distinguish the two branches as "Western Siouan" and "Eastern Siouan" or as "Siouan-proper" and "Catawban". Others restrict the name "Siouan" to the western branch and use the name "Siouan–Catawban" for the entire family. Generally, however, the name "Siouan" is used without distinction.
Tutelo language
Tutelo, also known as Tutelo–Saponi, is a member of the Virginian branch of Siouan languages that was originally spoken in what is now Virginia and West Virginia, as well as in the later travels of the speakers through North Carolina, Pennsylvania, New York, and finally, Ontario.
