About Castro Valley, CA

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, 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 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.
