Rancho Mission Vieja de la Purísima

Rancho Mission Vieja de la Purísima was a 4,414-acre (17.86 km2) Mexican land grant in present-day northern Santa Barbara County, California given in 1845 by Governor Pío Pico to Joaquín Carrillo and José Antonio Carrillo.

[1] The grant included the original site of Mission La Purísima Concepción, located north of present-day Lompoc.

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.

As required by the Land Act of 1851, a claim for Rancho Mission Vieja de la Purisma was filed with the Public Land Commission in 1852,[5][6] and the grant was patented to Joaquín Carrillo and José Antonio Carrillo in 1873.

The droughts of the early 1860s forced the More brothers to dissolve their partnership and divide up their lands.
