The Ohlone eventually regathered in multi-ethnic rancherias, along with other Mission Indians from families that spoke the Coast Miwok, Bay Miwok, Plains Miwok, Patwin, Yokuts, and Esselen languages. Many of the Ohlone that had survived the experience at Mission San Jose went to work at "Alisal Rancheria" in Pleasanton, and "El Molino" in Niles. Communities of mission survivors also formed in Sunol, Monterey and San Juan Bautista. In the 1840s a wave of United States settlers encroached into the area, and California became annexed to the United States. The new settlers brought in new diseases to the Ohlone.
