Hi hallmark,
Thanks for the information although I have actually taken a photo of that particular headstone in the graveyard at St John's (Kilcrow) church of Ireland. There seems to be quite a few Lee families living in the Dartry area, unfortunately I have been unable to trace any that were related to my lot.
My Great, Great Grandfather William Lee married Mary Jane McKeon from Kilmore West in St John's Church on the 13 July 1852. About 1867, the whole family moved North to Belfast.
Thanks again.
Dave
