My husband, Julius Ray Ivester, MD, was a descendent of Hugh who married Eve Lingerfelt. That Hugh had a son, Anderson Hugh, who married Arzella Moss, moved to SC, (now Walhalla) had a son Julius (1856) who married Tjide von Lehe. They had son, John Christopher, who was my husband's father. I have been to the Orkney Isles and agree with your research. My son, JRI, Jr., as well as Ivesters in Walhalla are descendents.
