Derivation: From the Wintun word yuki, meaning “stranger;” secondarily, “bad” or “thieving.”

A vocabulary of the Yuki tribe is given by Gibbs in vol. III of Schoolcraft’s Indian Tribes, 1853, but no indication is afforded that the language is of a distinct stock.

Powell, as above cited, appears to have been the first to separate the language.

[GEOGRAPHIC DISTRIBUTION.]

Round Valley, California, subsequently made a reservation to receive the Yuki and other tribes, was formerly the chief seat of the tribes of the family, but they also extended across the mountains to the coast.

Ashochimi (near Healdsburgh).
