Rancho Yokaya (also called "Llokaya") was a 35,541-acre (143.83 km2) Mexican land grant in present day Mendocino County, California given in 1845 by Governor Pío Pico to Cayetano Juarez.
[2] The grant extended along the Russian River from the southern end of Ukiah Valley to the northern end of Redwood Valley, from one to two miles wide, and approximating sixteen miles in length, and encompassed present day Ukiah.
For his decade of service to the Mexican government, Juárez was granted Rancho Tulucay in present day Napa County, California in 1840.
Although often away, Juárez resided on Rancho Tulucay until his death in 1883, and is buried in the Tulocay Cemetery in Napa, California.
[5] 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.
