hi frank,
I had posted that last note about an hour ago and I got on the sec'y of state web site, looked at everything I couls see that might have anything to do with the civil war and found nothing of Samuel. I found a roster page but the only chapman was buel (I think is correct spelling). he was last name on that page, go to the next page and there was no chapman name listed.
I did a search by name, first by itself, last by itself, first and last together, by unit, by location, found a page that was called muster and description, got nothing for a Samuel chapman.
you are not dealing with the sharpest knife in the drawer so I guess you will have to post the web address for that very page you were looking at for me.
sorry,
mike
