Rancho San Jacinto Nuevo y Potrero

Rancho San Jacinto Nuevo y Potrero was a 48,861-acre (197.73 km2) Mexican land grant in present-day Riverside County, California given in 1846 by Governor Pío Pico to Miguel Pedrorena.

José Antonio Estudillo was appointed administrator and major domo at Mission San Luis Rey in 1840.

[3] 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 San Jacinto Nuevo y Potrero was filed with the Public Land Commission in 1852,[4][5] and the grant was patented to T. W. Sutherland, guardian of the minor children of Miguel Pedrorena in 1883.

[6] In 1853, José Antonio Aguirre (1799–1860) of Rancho San Jacinto Sobrante bought Rancho San Jacinto Nuevo y Potrero from the estate of Miguel Pedrorena.
