Born in Collins Settlement, Virginia (now West Virginia), he attended school in Sutton, Virginia (now West Virginia). He was appointed as a cadet to the United States Military Academy at West Point from 1846 until 1848, when he resigned. He studied law, was admitted to the bar and commenced practice in Sutton in 1851; he was appointed the same year prosecuting attorney for Braxton County.
