Rancho Potrero de Felipe Lugo was a 2,043-acre (8.27 km2) Mexican land grant in present day Los Angeles County, California given in 1845 by Governor Pío Pico to Teodoro Romero and Jorge Morillo.
The grant along the San Gabriel River encompassed present day South El Monte.
[2][3] Jorge Morrillo and his son-in-law Teodoro Romero received the Rancho Potrero de Felipe Lugo grant.
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 Potrero de Felipe Lugo was filed with the Public Land Commission in 1853, [4][5] and the grant was patented to Jorge Morillo and Juana María Verdugo de Romero in 1871.
