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, Victor Linares made a claim for 1,000 varas square[1][2] on February 12, 1852, and it was confirmed by the commission March 14, 1853, by the district court January 14, 1857. An appeal was dismissed June 3, 1859.[3] The grant was patented to Michaela Linares et al. on August 9, 1866.[4]
The Ranchito was located along San Luis Creek, south of the Mission lands and on the road between the Mission and the port of San Luis Obispo. It shared a common boundary with the Mission lands of the Rancho La Laguna on the west.[5]
