Rancho Otay

Rancho Otay was a 6,658-acre (26.94 km2) Mexican land grant in present-day San Diego County, California, given in 1829 by Governor José María de Echeandía to Magdelena Estudillo.

The two square league grant was made to Magdalena Estudillo, whose brother, José Antonio Estudillo, was grantee of the adjoining one square league Rancho Janal.

The two grants, both to members of the Estudillo family, are often considered as one rancho.

The Estudillos were absentee ranchers, living in Pueblo de San Diego.

[2] With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
