I have an ancestor who vanished around the time of the Civil War and can only assume he fought in it. I've found about 20 possibilities for him at http://www.itd.nps.gov/ which is a small fortune to request all those files (north & south) plus others for other family names. Can anyone advise of a way to narrow down people in some way? All I can go on is the city I assume he lived in and the wife's first name at signup, if he didn't move and was still married. I've not found a burial found for him either. I assume he still lived in Cincinnati, but I don't know which side he would have fought for or where he would have signed up at. I've found with some research I've done, it's very confusing. Thanks! I've been lost with this searching for years.
