Page "Mission San José (California)" Paragraph 4

By the end of 1800 the neophyte population had risen to 277, including both Ohlone and Bay Miwok speakers.

By the end of 1805 all Indians of the East Bay south of Carquinez Strait were at the missions.

After a devastating measles epidemic that reduced the mission population by one quarter in 1806, people from more distant areas and new language groups began to join the Mission San Jose community.

The first such language group was the Yokuts or Yokutsan, whose speakers began to move to Mission San José from the San Joaquin Valley in 1810.

Members of two more language groups, the Coast Miwok from present Sonoma County and Patwin from present Napa and Solano counties, moved down to Mission San Jose in the 1812-1818 period, but in smaller numbers than the Yokuts.

By 1825 Delta Yokuts was the dominant language in the multi-lingual community of 1, 796 people.

Over the next few years speakers of yet another language group, Plains Miwok, moved to the mission from the north side of the Sacramento-San Joaquin River Delta.

By the time Mission San Jose was closed as an agricultural commune in the mid-1830s, Plains Miwok was the predominate native language among its neophyte Indian people ( Milliken 2008 ).
