Rancho Yajome was a 6,654-acre (26.93 km2) Mexican land grant in present day Napa County, California given in 1841 by Governor Juan Alvarado to Damaso Rodríguez, a soldier who did not occupy the property.
[2] The one and a half leagues were granted to Damaso Antonio Rodríguez (1782 - 1847).
While officially being an invalido, he was at Sonoma from 1837 in the service of General Mariano Guadalupe Vallejo.
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.
[6] The Silverado Country Club is located on 1,200 acres (4.9 km2) of the rancho acquired by General John Franklin Miller in 1869, 1873 and 1881.
