Ran­cho Cor­ral de Piedra was a 30,911-acre (125.09 km2) Mex­i­can land grant in present day San Luis Obispo County, Cal­i­for­nia con­sist­ing of two square leagues given in 1841 by Gov­er­nor Juan B. Alvarado to José María Villav­i­cen­cio, with an exten­sion of five square leagues given in 1846, by Gov­er­nor Pio Pico. The grant was located between present day San Luis Obispo and Arroyo Grande, and bounded on the south by Arroyo Grande Creek. José María Teodoro Villav­i­cen­cio (1800–1853), called for brevity Villa, was the sec­ond son of Rafael de Jesus Villav­i­cen­cio (a sol­dier and mem­ber of the Por­tola expe­di­tion) and Maria Ilde­fonsa Berges. José María Villav­i­cen­cio retired as cap­tain of the mili­tia at Mon­terey, and was admin­is­tra­tor at Mis­sion San Anto­nio and Mis­sion San Fer­nando. Villav­i­cen­cio mar­ried Rafaela Rodríguez the daugh­ter of Sebas­t­ian Rodríguez grantee of Ran­cho Bolsa del Pajaro. His brother, Rafael Villav­i­cen­cio was the grantee of Ran­cho San Geron­imo. 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 Cor­ral de Piedra was filed with the Pub­lic Land Com­mis­sion in 1852, and the grant was patented to José María Villav­i­cen­cio in 1867. When José María Villav­i­cen­cio died in 1853, he left the ran­cho to his seven chil­dren. In 1860, his widow Rafaela bor­rowed money from her brother Jac­into Rodriguez. In 1866, Rodríguez con­vinced the heirs to sell him the entire ran­cho, which he sold to dairy­men George Steele and his broth­ers Edgar W., Isaac C., and Rens­se­laer E. Steele. In 1867, the heirs decided that the sale to Rodríguez was not legal, and sold six-sevenths of the ran­cho to George Alexander In cur­rent times… the ranch was re-purchased in 1973. At that time… the ranch had very lit­tle water, so we bought the ranch next to 3S (that had water) and we piped it in. Then about 13 or 14 years later we went ahead and had a well dug (on the prop­erty) and found a well that pro­duced between 2 and 4 thou­sand gal­lons per minute… nowa­days the ranch is cur­rently being use as cat­tle & veg­etable ranch.
