Rancho Laguna de la Merced (also known as the Galindo ranch) was a 2,219-acre (8.98 km2) Mexican land grant, in present-day southwestern San Francisco and northwestern San Mateo County, California.
It was given in 1835 by Governor José Castro to José Antonio Galindo.
The grant encompassed the area around Lake Merced in San Francisco and the present day Daly City neighborhoods of Westlake, and Serramonte.
José Galindo was a corporal in the Presidio of San Francisco militia in Alta California. His grandfather, Nicolás Galindo, had accompanied the De Anza Expedition as a settler in Las Californias province in 1776. In 1835, José Antonio Galindo was granted the one half square league Rancho Laguna de la Merced around Lake Merced, and also received the Rancho Saucelito grant, in Alta California. His widowed mother, Ramona Sanchez de Galindo, was the grantee of Rancho Butano in 1838.
José Antonio Galindo did little to develop Rancho Laguna de la Merced and sold it in 1837 to Francisco de Haro (1792 – 1849). In a strange turn of events, in 1838, Alcalde De Haro arrested José Antonio Galindo for the murder of José Doroteo Peralta (1810 - 1838), son of Pedro Peralta. De Haro's wife, Emiliana Sanchez, died in 1842, and De Haro died in 1849.
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 Laguna de la Merced was filed with the Public Land Commission in 1852, and the grant was patented in 1872 to the surviving De Haro children - Josefa de Haro Guerrero Denniston, Rosalia de Haro Andrews Brown, Natividad de Haro Castro Tissot, and Carlotta de Haro Denniston.
