Rancho Tepusquet

Rancho Tepusquet was a 8,901-acre (36.02 km2) Mexican land grant in present-day northern Santa Barbara County, California given in 1837 by Governor Juan B. Alvarado to Tomás Olivera.

By her previous marriage, María Antonia Cota had daughters: María Martina Osuna (who married Juan Pacifico Ontiveros of Rancho San Juan Cajón de Santa Ana in 1825)[4] and Eduarda Osuna (who married Benjamin Foxen of Rancho Tinaquaic in 1831).

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.

[7] In 1855, the heirs of Tomás Olivera sold Rancho Tepusquet to step daughter, María Martina Osuna (1809–1898) and son-in-law Juan Pacifico Ontiveros (1795–1877).

Juan Pacifico Ontiveros moved to Rancho Tepusquet in 1856, and constructed an adobe on the property, where he lived until his death.

In 1855, Juan Pacífico Ontiveros purchased Rancho Tepusquet, which included all of modern-day Sisquoc and Garey .
