Rancho Santa Clara del Norte
Rancho Santa Clara del Norte was a 13,989-acre (56.61 km2) Mexican land grant in present day Ventura County, California given in 1837 by Governor Juan B. Alvarado to Juan Maria Sanchez. The grant extended along the south bank of the Santa Clara River, east of present day Oxnard and encompasses El Rio.
Juan Maria Sanchez (1791–1873), son of Jose Tadeo Sanchez, was a former Presidio of Santa Barbara soldier. He married Maria Ynes Josefa Guevara (1794–1862).
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 Santa Clara del Norte was filed with the Public Land Commission in 1852, and the grant was patented to Juan Maria Sanchez in 1869.
Following the droughts in 1864, Sanchez sold Rancho Santa Clara del Norte to the Schiappa Pietra brothers, natives of Italy. Antonio Schiappa Pietra (1832–1895) came to California in 1853, and opened a general merchandise store in Ventura in 1857. He was joined by his brothers Frederico Schiappa Pietra (–1867) and Leopoldo Schiappa Pietra (1842–). In 1902, Leopoldo sold the rancho to California Farm and Fruit Company of Manchester.
