Tutelo Indians. One of the eastern Siouan tribes, formerly living in Virginia and North Carolina, but now extinct. Hale first made it known that the Tutelo language pertained to the Siouan stock, a discovery which, followed by the investigations of Gatschet, Mooney, and J. O. Dorsey, brought to light the fact that a considerable group of Siouan tribes formerly inhabited the piedmont region of Virginia and the Carolinas.
