Rancho Llano de Santa Rosa was a 13,316-acre (53.89 km2) Mexican land grant in present-day Sonoma County, California given in 1844 by Governor Manuel Micheltorena to Joaquín Carrillo.
Joaquín Carrillo was the owner of two Sebastopol hotels (the Analy and the Pioneer), a saloon and a boarding house.
[7] 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.
[10] A claim for one square league was filed with the Land Commission in 1852 by John Hendley and Joseph N. Nevill, but was rejected.
[11] Dr. John Hendley (1820–1875) was born in Lexington, Kentucky, had been assistant surgeon in a Missouri volunteer regiment, and came to California in 1850, settling in the following year on his farm, where he died.
