What a wonderful person you are to do this. I've been looking for the grave sites of Evan Edwards (1834 - 1895), his wife Ann(e) Dwyer Edwards (1830ish - 1904) and their son Edward Thomas Edwards (1861 - 1930). I assume (I know that's a no-no in genealogy!) that they might have had a family plot.
If you come across this family I would greatly appreciate any information you may have found. You can email me at: firstname.lastname@example.org
