History
Before the arrival of European settlers the area was settled by the Chocheño (also spelled Chochenyo or Chocenyo) subdivision of the Ohlone Native Americans.
With the arrival of Europeans, they established Mission San Jose in 1797. The area Castro Valley now occupies was part of the extensive colony of New Spain in what was the province of Alta California.
Castro Valley was part of the original 28,000 acre (110 km2) land grant given to Castro in 1840, 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 town of Atherton is named) in turn began selling off his portion in smaller parcels. Two men 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.
