I honestly do not know since the only way I knew anything in the beginning about the 1st was
when I discovered Fielding Price was a Lt. with the 1st, according to Rebel's Hell that was from the National Archives.
According to what I remember Bryan saying, unless they were captured or died, there were no records
to prove they were there. He has pieced them together and the last time I asked was five years ago.
But it is possible your ancestor and my ancestor served together at one time or another.
