Sometime after 1814, Juan Pablo Peralta I, co-grantee of the Rancho Santiago de Santa Ana, built his adobe home east of here. His children, and their children in turn, built theirs near his. In 1871, Peralta was comprised of a small cluster of adobe homes belonging to Ramon Peralta, Gertruda Peralta Moreno, Nieves Lopez Peralta, Paula Peralta Dominguez, Trinidad Peralta Marquez and Josefa Peralta Feliz. Today, the Ramon Peralta Adobe is the only surviving structure.
