Well I only have info I have gotten from others that say Peter married Clara Ridenour. The only written proof I have is a death certificate of his youngest son Milton. It says his mother was Clara Ridenour. If I could get the whole set of Peter Cooper's military records it should say his wife's name. I don't know where to send for them right now. I haven't had time to look for it. I wish he had left a will but then that wouldn't help either. She would already be gone by then. I have Peter's pension records but it only has his second wife in it. Sure is a hard line to work on. Too many records are missing. Let me know if you get your papers in order and find what you have on him. Nice talking to you.
