Rancho Ulistac was a 2,217-acre (8.97 km2) Mexican land grant in present-day Santa Clara County, California, given in 1845 by Governor Pío Pico to Marcello and Cristobal, Indians.
[1] The grant extended across lowlands reaching from the Alviso shoreline southward and encompassing the land between the Guadalupe River and Saratoga Creek, and the town of Agnew.
[2][3][4] In 1846, Governor Pico granted one-half square league to Santa Clara Mission Indian Marcello and his nephews Pio and Cristobal.
[7] Hoppe was killed in the explosion of the SS Jenny Lind en route from Alviso to San Francisco on April 11, 1853.
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.
