It can be pretty hard when we get back so far but if someone has gone in on your ancestor already I will be happy to look in my DAR Lineage Books and I can copy off and snail mail a copy of what I find; OR if you have a Library close where you can check, that would be good. Since I am Registrar for my Chapter, I tend to write Washington for a copy of the latest ~~~~~say, oh, two or three sets of papers of ladies who have joined on the particular line I am interested in. Now, if those papers have been accepted in the last 10 years or so, then we can probably be lucky and National will accept the work done previously [should it be fortunate enough to tie in with you] but in any case, they should at least accept the Ancestor and his wife , so that means you would not have to prove that, just indicate the National Numbers on a couple of sets of papers that someone has gone in on [if of coarse, they are YOUR ancestor, natch]. Then, its good if you can locate service record of your ancestor at the National Archives; and if he received a Pension or his wife received a Widow's pension there should be a document that could be copied and sent to you of that. One of the documents I found [turned out it wasn't MY Hugh Rogers, dang it] but he was eligible for a pension and the wife had written out a paper or dictated it naming their children and their birth dates. She also had someone that had known them for a long time and there was a copy of that included also when I was sent the copies of what was in the National Archives on this matter. Another thing that always helps is a Will, Tax Lists help and so on. Claire
