“The Serranos (Spanish, “mountaineers”), a Shoshonean branch comprising numerous local groups, occupied San Bernardino valley, San Bernardino mountains north of Los Angeles and San Bernardino, a portion of Mojave desert north of that range and east of Mojave river, and Tehachapi mountains. This last group, who lived principally on El Paso and Tejon creeks, were the Kitanemuk. In 1853 most of the resident Indians, including not only various Shoshoneans but many Yokuts, were taken to Tule river reservation. Tejon rancheria remains, however, a settlement of various Shoshoneans, but predominantly Kitanemuk”
