I know that it has been some time since you were using this thread, but I recently got my DNA match through ancestry and two other users match to me and assure me that they link to me through John Darragh of Coleraine and/or his wife. This has been a great surprise as I thought our family origins were Limavady and Ballymoney. Two other DNA links from Family Finder give me cause to believe I have ancestry at Loughan/Damhead, and I see there were quite a few Darragh surnames there in the 19th century and more recently - does anyone know if John of Killowen was their relative, or if there are links to Campbell or Spallen/Spalling of Damhead in that era? Or perhaps Logan, Olphert St, Coleraine town? And finally do any of these names link to Limavady rural area McDonald, McGuinness, Loughhry, Neill, White or Morrison in late 1900s?
