Little History About Castro Valley California

By: TheFreeDictionary
Before the arrival of European settlers, the area was settled by the Chocheño (also Chochenyo and 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 state of Alta California.

Castro Valley is named after Don Guillermo Castro, who was a soldier in the Mexican army and rancher. Castro Valley was part of the original 28,000 acre 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 Canyon. Castro had a gambling habit and had to self off portions of his land to pay for gambling debts. The last of his holding was sold in a sherrif's sale in 1864 to Faxon Dean Atherton for $400,000.

Atherton, whom the city of Atherton is named after, in turn began selling of his portion in smaller parcels. Two gentlemen named Cull (the namesake of Cull Canyon) and Luce bought some 2400 acres 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.  
Being unincorporated, it is governed by the county and does not have any city services. To date, all efforts to incorporate Castro Valley have been voted down by its residents. To find out more please check out the book below.

Castro Valley History Book:
An officer in the Mexican army bequeathed his name to the crescent-shaped basin once known as Castro’s Valley. Driven to ruin by squatters, drought, and gambling debts, he sold a portion of his cattle ranch to Methodist minister Zachariah Hughes, who built a church and school in what is now Crow Canyon. The one-room, redwood school Hughes christened Eden Vale educated about 50 children until a group from the burgeoning town to the south, “Hayward’s,” stole it by wagon in the dead of night. Undaunted, Castro Valley, delineated from its now friendly neighbors by hills, Lake Chabot, and an independent spirit, built and fully supported its own Redwood School. It has now developed into one of the most populous unincorporated areas in the United States. Castro, a gambler, was forced to sell his land to pay his debts, and he sailed for Chile in 1864. Methodist minister Zachariah Hughes and William Mattox were among those who purchased large tracts from Castro. Several families who settled in the area operated huge cattle and poultry ranches.
