Hi Lisa,Joe Doughty here Arkansas I dont think Joseph Doughty and wife Nancy Lucas went out of Country during the Rev.. They were right there in upper SC on Wildcat Creek of the South Fork of the Tigar River-right next to the Charles Lucas family.Charles Lucas may have been the Charles Lucas that fought under command of Francis Marion the swamp fox.
Joseph Doughty's uncle Jeremiah Doty was a captain in the Upper SC Militia and has a proven lineage back to Edward Doty of the Mayflower.This same Jeremiah signed the land document as one of the witnesses when Joseph Doughty sold his land on Wildcat Creek in 1789.
He got the land by a land warrent(1784) issued to him by John Thomas who was a leader of the Upper SC Militia, and after the Rev War made one of the first land warrant officers. Joseph Doughty and a batch of others who had been squatting on this land in what now is Greenville County SC were the first paper land owners of the area.
I suspect Joseph Doughty and young family were maily focused during the Rev with staying alive, and perhaps at times he did join the units of Jeremiah Doty or General Pickins - No war records have ever been found - but i think it says a lot that he was able to get land in the area from folks that do have a war record and knew the folks of the area like John Thomas .
As you know Joseph Doughty died in SC in 1815 near Seneca in what now is Oconee County.Many vets of the Rev War got land in Oconee County......... here again birds of a feather flock together.
The first record of Joseph Doughty in SC was in an early newspaper dated 1772 - he is listed as Joseph Dotay as seen on the Upper Tygar River.
So Joseph Doughty and family and others were on the Upper Tygar River during the Rev War and at that time this would have been Cherokee land, but by no way did this remove them from the Rev War and even worse the civil war in SC.jcd
