Ok for those wanting the info, this is what my grandfather John Paul Fowler told me.
James William was born a Barton. Upon returning from serving in a was, presumably the Revolutionary War (1775 to 1783), found his family had either left or had been killed.He then lived with a neighbor family named Fowler and took their name.James had no known siblings. It is possible that James William moved to South Carolina possibly Spartenburg. James was born of German heritage.
These Fowlers moved to Forsyth then Paulding County Ga
