Castro Valley sign


Castro Valley is named after Don Guillermo Castro, who was a soldier in the Mexican army and a rancher. Castro Valley was part of the original 28,000 acre (110 km²) land grant given to Castro, called Rancho San Lorenzo.  This land grant included Hayward, San Lorenzo, and Castro Valley, including Crow Canyon, Cull Canyon, and Palomares Canyons. Castro had a gambling habit and had to sell off portions of his land to pay gambling debts. The last of his holding was sold in a sheriff’s sale in 1864 to Faxon Atherton for $400,000.

Atherton (after whom the city of Atherton is namedin turn began selling off his portion in smaller parcels. Two gentlemen named Cull (the namesake of Cull Canyon) and Luce bought some 2,400 acres (10 km²) and began running a steam-operated saw mill in Redwood Canyon. The Jensen brothers also bought land from Atherton in 1867.
