Castro Valley Information
Before the arrival of European settlers the area was settled by the Chocheño (also Chochenyo or Chocenyo) subdivision of the Ohlone Native Americans.
With the arrival of Europeans, Castro Valley was part of the land granted to Mission San Jose in 1797. The area Castro Valley now occupies was part of the extensive colony of New Spain in what was the state of Alta California.
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 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 Atherton (after whom the city of in 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.
During the 1940s and 1950s, Castro Valley was known for its chicken ranches. Later it developed into a bedroom community, where workers live and commute to their jobs in the surrounding communities.
