Nanatsoho Indians. Probably a subdivision of one of the tribes of the Caddo confederacy which resided in a village on Red river, of Louisiana, and, according to Joutel, were allies of the Kadohadacho, Natchitoch and Nasoni in 1687. They probably drifted southward in the middle of the 18th century, gradually lost, their distinctive organization, and became merged with their kindred during the turbulence of that period, suffering distress incident to the introduction of new diseases by the whites. In 1812 a settlement of 12 families was said to exist near the locality of their former villages.
