After Mexico became independent from Spain, what is now Chula Vista became part of Alta California. Beginning in 1829, the land that is now Chula Vista was divided among Rancho Janal, Rancho Otay, Rancho de la Nación and Rancho La Punta; these were owned by José María Estudillo, José's sister Maria, John (Don Juan) Forster, and Santiago E. Argüello respectively.
