James Alexander Forbes (1805–1881), born in
Scotland, came to
Yerba Buena in 1831. He moved to the
Santa Clara Valley, where married Maria Ana Galindo, whose father, José Crisóstomo Galindo, was the majordomo of the Santa Clara Mission. Forbes was granted the one square league Rancho Potrero de Santa Clara in 1844. Forbes sold the Rancho to Commodore
Robert F. Stockton in 1847. 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 Santa Clara was filed with the
Public Land Commission in 1852, and the grant was
patented to Robert F. Stockton in 1861. A second claim was filed by José M. Fuentes, but was rejected due to lack of evidence. In the 1862 Stockton sold the rancho to
Charles B. Polhemus and
Henry Newhall, who planned to run railroad tracks through the valley. ==Landmark status==
