Tara,
I believe it costs to have look-ups done and copies made from the Nat'l. Archives. It is cheaper and faster to go to your local library. I have found that most states have books with listing of War Veterans. I'd try there first. It is cheaper and faster. With the Nat'l. Archives you have to wait for them to do the look-ups and mail the copies to you. If you do it, it may only take a few hours.
