I am looking for my GG Uncle. The last known whereabouts was Libby Prison. His name is John Harriman and our family have been trying to locate where he might have gone. John Harriman is said to be born around 1833 in NH. He had a brother that also served with him name Allen Obediah Harriman. His father is Obediah Harriman and mother Hannah Hart. If anyone can help that would be greatly appreciated.
