[4] José María Rojo was granted the five square league Rancho Cuyama in 1843.
Cesario Armand Lataillade (1819–1849) was a French trader involved in the hide and tallow trade who came to Santa Barbara in 1841.
[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.
As required by the Land Act of 1851, a claim for Rancho Cuyama was filed with the Public Land Commission in 1852,[6][7] and the grant was patented to María Antonia de la Guerra y Lataillade in 1877.
