George Chase, was Deputy Treasurer of Alameda County. He was born in Newburyport, Massachusetts (1841), a son of Moses and Emily (Stickney) Chase. The Chase family subsequently settled in Brooklyn (Clinton), California, now part of Oakland. The father of George Chase came to California in 1849. There, he supported himself on West Oakland Point by hunting. He joined in partnership with the Patten brothers and obtained land in Clinton which they subdivided into building lots. They built the first hotel in East Oakland, called the Clinton House. Moses Chase returned East in 1853 to visit family and in his absence the Clinton House burned. He returned to California the same year. Son George came to California (1854) in company with his aunt Mary and her husband, James Allen. George's mother, Emily (Stickney) Chase, had died when George was a baby.
