Thank you Paul for your reply.
It has been several years since I was out there. My father and I stopped at the church office and then went to the cemetery.
The McGrath's grave is not marked with a headstone. I don't know why. Might have been a sibling dispute between Elizabeth and her sister. As I remember it, it is from the right of the cemetery (looking north) on the last row. There are several headstones to the right of their gravesite and nothing on their gravesite to indicate where they were buried.
Also, my father's aunt passed away since the last time we visited the cemetery. The Donohoe clan is located in the circle drive with the headstones erected by Elizabeth Wedding. If possible, can you get me current pictures so that I can update my files.
You can email them to research at hannigangenealogy.us and that would be fantastic.
