The region comprising the future city of San Francisco was controlled by the Yelamu tribal group of Ohlone Indians. The first four people from Yelamu were baptized between 1777-1779 at Mission Dolores.

Over a period of time, the Spanish friars of Mission Dolores baptized the extended family of a Yelamu chief named Xigmacse who was identified as the "Captain of the village of this place of the Mission".
