Jesse P. Hanna and his sons, David, John, James, and R. M. settled in 1856 in Brown County, near the Colorado River, about ten miles below the place where the Frisco railroad crosses it now, in a valley that now bears their name. David Hanna was well educated and took a very active part in the county affairs and assisted in the development of the county. He was one of the first four commissioners elected in Brown county. He also served on the first grand jury in the county. David Hanna later joined the Texas Rangers, commanded by Captain John. William, who was killed in 1868 at Babyhead Mountain in Llano county. Hanna was also the father of the first white child born in Brown County.
