Do you know which Robert Giffen served in Rev War from PA? I found him while looking for Thomas Gourley's(PA>TN) Rev War Record. A lot of PA surnames turn up in E TN after Rev War. These are the names I found with possible ties to E TN. All served in PA:Samuel Ralston,Conrad Best,William Downing,Phillip Correll,Frederick Emertt,John Richey,Lazarus Rine,Archibald
Gilleland,Andrew Grey,George Glass,John Boyd,James Robinson,Thomas and James Green.My g nephew descends from a long line of Robert Giffins in E TN.
