Rancho Soquel was a 1,668-acre (6.75 km2) Mexican land grant in present-day Santa Cruz County, California given in 1833 by Governor José Figueroa to María Martina Castro y Amador.
Martina married Irishman Michael Lodge (1797–1849) in 1831, and she was granted the half square league Rancho Soquel in 1833.
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.
[12] In Depeaux's absence, Martina gave each of her remaining eight children an undivided one-ninth of the Rancho Soquel grant.
[13] In 1856, with the onset of mental instability, Martina sold her remaining land and spent her last years with her daughter Guadalupe in Capitola until her death in 1890.
