Rancho Olómpali

Rancho Olómpali was a 8,877-acre (35.92 km2) Mexican land grant in present-day Marin County, California given in 1834 by governor Manuel Micheltorena to Camilo Ynitia, son of a Coast Miwok chief.

[7] Camilo was the only Native American on the northern frontier of Alta California to secure and keep a large land grant for his tribe.

[8] 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.

[11] In 1852 Ynitia sold most of his land to James Black, grantee of Rancho Cañada de Jonive and one of the largest landowners in Marin County.

Black's wife, Maria Agustina Sais, died in Dr. Burdell's dental chair in 1864.
