Just so I am following you. You are suggesting that the parents of John Fargher (d. 1782 Lonan) are Thomas and Ann Fargher, and NOT the John Fargher and Margaret Fargher als Corlet mentioned in the below Wills. You think this because Thomas and Ann are from Graue (Grawe?) and John and Margaret are from Baldrine? Or have I completely misunderstand you.

FARGHER'S parents could be: 1: John Fargher (1765-1 A 1 FARGHER John [bur Lon 17650131]d 29 1765; baldrine;dau margt, jane; sons john,wm;wife mary als kinley;daus ua ;) and 2) MARGARET FARGHER als CORLET (1758-2 E w FARGHER Margaret CORLET [bur Lon 17580429];dated 21 aug 1757;son john (eldest),wm;bro daid corlet (dau margt);serv isable lewn;wm corlett's poor dau;husb john).
