Rancho Buena Vista was a 2,288-acre (9.26 km2) Mexican land grant in present day San Diego County, California given in 1845 by Governor Pío Pico to Felipe, an Indian. The name means "good view" in Spanish. The grant was south of San Luis Rey River and Rancho Monserate and encompassed present day Vista.
Formerly a part of Mission San Luis Rey lands, the grant was made to Felipe Subria, a mission Indian. His daughter Maria La Garcia, who married William B. Dunn, inherited the property, and then sold it to Jesus Machado.
(** Please check your original source for stating that Maria La Gracia sold BV to Jesus Machado; according to land claims recorded, and publicly available at the BLM online, Jesus Machado's claim was founded on the claim of "Indian Felipe (Subria), a Native of Mission San Luis Rey".) 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 was filed with the Public Land Commission in 1853, and the grant was patented to Jesús Machado.
Jesús Machado (1823- ) married 1850 Lugarda Osuna de Alvarado, whose husband, José María Alvarado, had been killed in the Pauma Massacre. When Jesús Machado was killed by Indians, his son, Luis G. Machado, inherited the rancho. Lorenzo Soto acquired the rancho from foreclosure in 1860. Lorenzo Soto (1821-1863) was the son of Francisco Soto of Rancho San Lorenzo Baja. Soto married María Ygnacia Morena, after his first wife died in 1857. After Lorenzo Soto’s death, his wife married Tomas Alvarado of Rancho Monserate. They then sold the Rancho to Cave Johnson Couts in 1866.
