For starters, there is no proof that Elizabeth, wife of William McGaha, and mother of Samuel and Mary, and who lived in Cocke Co, Tn, was a Burlison. That was my speculation based on Samuel naming a son Isaac Burlison McGaha and having Isaac Burlison as a neighbor. That Isaac Burlison deeded land in Cocke County to Elizabeth McGaughey, but the deed is torn and hard to read and has the date missing.
2nd, there was an older Samuel McGaha living in the Big Ivy area of Buncombe Co, NC (now Madison Co) with Isaac Burlison, John Giles, William Ramsey, and Holoway Giles as neighbors. I suspect this Samuel was the father of William, who married Elizabeth.
FYI - Elizabeth remarried to Henry Miller after William died.
If anyone has proof that Elizabeth was a Burlison, I'd like a copy.
Have any of the McGaha men had their Y-DNA tested to see if it matches the clan of William McGaughey of Pennsylvania?
