Is there any place that would have an archived copy of a death notice (one that was sent to the family) of a soldier? I understand they were sent from the Army's casualty branch to a bunch of different places.
Try starting here http://www.archives.gov/veterans/ If you would like to post the name of the soldier and what information you have we may be able to help you out also. There are a few rogues on here that live for just that sort of thing
It'd be better to stay with the one thread you have going if it is on the same person. Otherwise we'll end up chasing our tails and finding repeat information you already have.
