Thanks Dave and all. Have seen several graveyards in Fermanagh and the conditions that the headstones were in. ( they had already been photographed) Was just curious. Found an old headstone in Newark NJ where the caretaker had to dig up the stone as the cemetery had laid many old ones flat with dirt and grass over them for ease of caring for the cemetery. This did preserve them.
