The story

from WikipediaRead it all ↗

Prior to European contact, the indigenous Patwin tribe lived in the area with the Ululato tribelet, establishing a chiefdom around the Ululato village in what is now downtown Vacaville along the Ulatis Creek.

The early settler pioneers of the land were Juan Manuel Cabeza Vaca and Juan Felipe Peña, who were awarded a 44,000-acre (18,000 ha) Mexican land grant in 1842. The same year, Vaca and Peña's families settled in the area of Lagoon Valley. Peña's Adobe home is the oldest standing building, built in 1842, now at Peña Adobe Park.
