Re: David T. Hoover/Daniel T. Hoover
I think you are misunderstanding the service record. The 18th OVI Co C lists Daniel T. Hoover as a substitute enlistee in 1865. That means he accepted money and took the place of someone else. He only served six months because the war was over and the regiment was being mustered out. Hope this helps.
