Yes, thanks. That he was a soldier during the war is sufficiently documented. The problem lies in documenting his parental relationship to John Doggett Brown the son who he had with his wife Lucy Doggett. I just searched the courthouse records in Culpeper, and they have nothing (most records were burned by the Yankees during the War of Northern Aggression). There is an off chance that this link will show up in the records of John Doggett Brown's marriage to Catherine Sample in 1812 in Loudoun Co. If those records only contain the marriage return, it will not be fruitful but of the marriage bond is available, it might have the father's name.
