John Rogers Cooper (1791-1872) came to Monterey, California from New England in 1823 as captain of the trading schooner Rover. In Alta California, Cooper became a Mexican citizen and took the name Juan Bautista Rogerio Cooper. He married Encarnacion Vallejo (1809-1902), sister of General Mariano Vallejo. In 1829, Cooper purchased Rancho Bolsa del Potrero y Moro Cojo, which sat between the Salinas River and the Tembladero Slough, near present Castroville. Rancho El Sur, a land grant made in 1834 by Governor Jose Figueroa to Juan Bautista Alvardo, was transferred to Cooper in 1840 in exchange for Rancho Bolsa del Potrero y Moro Cojo. Cooper's claim on Rancho El Sur was confirmed by the United States in 1866. Until the late 1920s, Rancho El Sur was a working ranch and farm operated by descendants of John B. Rogers Cooper, including daughter Amelia Cooper (1844-1918) and her husband Eusebio Joseph Molera (1846-1932), and Amelia's and Eusebio's children, Andrew J. Molera (1875-1931) and Frances Mary Molera (1879-1968). On this land currently sits Andrew Molera State Park.
