Don Guillermo Castro (1809-1866) was a Californio ranchero, officer in Mexican Army, local justice of the peace and surveyor who once owned vast land holdings in Alameda County. He is the namesake of the unincorporated community of Castro Valley, California and his land included most of the modern City of Hayward, California.
