Rancho Juristac was a 4,540-acre (18.4 km2) Mexican land grant in present-day Santa Clara County, California given in 1835 by Governor José Castro to Antonio and Faustino German.
[2][3] Antonio and his brother Faustino received the one square league Rancho Juristac land grant in 1835.
Faustino Jose German (1795–) married Antonia Maria de Jesus Garcia (1797–) in 1816.
James P. Sargent (1823–1890) was a native of New Hampshire who came to California in 1849 with his three brothers, Jacob L. (1818–1890), Roswell C. (1821–1903), and Bradley V. (1828–1893).
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.
