Rancho Pescadero (also called "Punta del Cipreses") was a 4,426-acre (17.91 km2) Mexican land grant in present day Monterey County, California given in 1836 by Governor Nicolás Gutiérrez to Fabián Barreto.
The grant extended along the Pacific coast from Rancho Punta de Pinos and Seal Rocks south to Carmel by the Sea and encompassed present day Pebble Beach, California.
The sudden death of the ill-fated Fabian Barreto, second husband of Maria, resulted in the passing of the land to John Romie and then to David Jacks.
(a more complete description of this transaction history (with date discrepancies) can be found on a website dealing with the Hart Mansion - hartmansion.com.)
María Madariaga re-sold the land to David Jacks, who owned the adjoining Rancho Aguajito to the east.
[6] 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.
