Bill: As possible leads to the units some of these men may have served in, I give you what I found from Jeff Weaver's Virginia Regimental History Series Index. Men with same or similar names may have served in different regiments. I do not have positive confirmation that the men on your list were the men in these units, but thought these leads might be a place to start.
