Jack, the familysearch pilot search has several entries for Cleghorn in Clones, Monaghan, which is next to Tedavnet. Aghabog is not far away, so likely there were connections. Your best bet for that time period is church records. I'm guessing from his name that George was Protestant. The LDS haven't filmed the Tedavnet or Aghabog Church of Ireland records, but they have filmed Clones. You might check that film. I know there's a repository of CofI records in Dublin. Maybe someone else on the list can steer you to that as a way to check Tedavnet and Aghabog. Diane
