Vikki,
With all of the detailed information you have you can obtain copies of the original muster records from the National Archives. I have copies of my Confederate ancestors surrender and parole records and they are detailed. I'm sure Union records would be much more detailed, and would probably include records of discharge. They may even contain pay records, clothing allotments, and any wounds or hospital time they may have served. You have alot of info already; happy hunting. bg
