Stewart GAMMIE and I are distant cousins (5C I think). My 4 x great-gran was Elizabeth GAMMIE born 1779 Marnoch Banffs, daughter of John GAMMIE and Elspet ELDER. Stewert descends from one of the sons .. I always forget which one!
Elizabeth married John REIDFORD b.1777 Marnoch, son of Joseph REIDFORD b.1745 Corskie Farm Marnoch and Isobel MURDOCH b.1757 Gamrie.
We have INGRAMs & MORRISONs, who would be in the direct line of descent as well.
