Rancho Cienega del Gabilan
Rancho Cienega del Gabilan was a 48,781-acre (197.41 km2) Mexican land grant in present day Monterey County and San Benito County, California given in 1843 by Governor Manuel Micheltorena to Antonio Chaves (Chávez). The name means "spring of the hawk ranch". The grant was located in the Gabilan Range east of present day Salinas. 
José Antonio Chávez, came to California in 1833 with Governor José Figueroa. He was tax collector at Monterey in 1843, and one of the prime movers in the movement against Manuel Micheltorena 1844. Chaves was the grantee of the eleven square league Rancho Cienega del Gabilan 1843 and the three square league Rancho Pleyto in 1845. He took part as Lieutenant in various military operations in the Mexican–American War of 1846. He was sent by José Castro to John C. Frémont's camp at Gavilan Peak. Later he kidnapped Thomas O. Larkin and was second in command at the Battle of Natividad, where he was wounded. He returned to Mexico in 1848.
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 Cienega del Gabilan was filed by José Yves Limantour with the Public Land Commission in 1853. José Yves Limantour, who became notorious for his fraudulent claims, maintained that he had bought the grant from Chaves. The land commission rejected his claim.
Thomas O. Larkin (1802 - 1858) claimed he bought Rancho Cienega del Gabilan from Chaves and received confirmation of it just after he died in 1858. Larkin had also bought Rancho Pleyto from Chaves.
