Skip, More information would make to task a little easier. If he was a Confederate and was captured at Stones River he may have been taken to Camp Chase. Using ancestery you could look at the various list of prisoners and see if he is listed. Also ancestery is more than just Camp Chase as it covers Camp Morton and Butler etc. If he was enlisted and he was a Confederate than I would suspect to find him in one of the following prison camps. Chase/Morton/Butler/Douglas/Rock Island. To answer your question exactly NARA in DC does have a total list of prisoners taken at Stones River as I was looking at it the other day. However the list is very long and it was either in record group 92 or 249.
