Rancho Punta de Quentin
Rancho Punta de Quentin was a 8,877-acre (35.92 km2) Mexican land grant in present-day Marin County, California given in 1840 by Governor Juan B. Alvarado to John B.R. Cooper. The grant comprised not only the San Quentin peninsula, but also present-day Ross, Kentfield and part of San Anselmo.
Captain John Bautista Rogers Cooper (1791–1872) married General Vallejo’s sister Encarnacion in 1827 and became a naturalized Mexican in 1830. In 1840, Governor Alvarado granted Cooper the two square league Rancho Punta de Quentin. His Marin holdings also included Rancho Nicasio, which he and Pablo de la Guerra were granted in 1844. Cooper established a lumber business, which he contracted others to run. In 1847, he leased a section of the point to the U.S. government for a sawmill. He sold his interests in both Marin County ranchos to Benjamin Rush Buckelew in 1850.
Benjamin Rush Buckelew (1822–1859) and his wife, Martha, came to California in 1846 with the Hoppe and Harlan wagon train. In San Francisco, he founded a watch making and jewelry shop, and manufactured gold scales for use by miners. He owned and operated the San Francisco newspaper The Californian(1847-48). In 1850, Buckelew bought three Marin County ranchos in 11 days. Besides Cooper’s Rancho Punta de Quentin, Buckelew also purchased Cooper’s Rancho Nicasio and John Reed’s Rancho Corte Madera del Presidio. In 1852, the California Legislature bought twenty acres at the tip of the rancho, where the Board of Prison Commissioners planned to build a state prison.
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 Punta de Quentin was filed with the Public Land Commission in 1853, and the grant was patented to Benjamin R. Buckelew in 1866.
