I think I just helped solve a bit of a riddle, and created a new one here.
The City of Niagara Falls has a Genealogy search for the grave years.
Oh btw, I am direct to Abraham and Thomas Garner too.
Thomas and Catharine I found are buried on Drummond Hill Cemetery (not too far from Laura Secord I might add), however I was never able to find Abraham Lampman Garner, then I thought about name changes etc... so I did a search and dropped the "Garner" name and just searched Abraham Lampman. Turns out there is one in Drummond Cemetery right beside Thomas and Catharine Garner. He is also buried with a Phebe Lampman. I think this is the Thomas and Phebe we are looking for,
Here is an added twist that we can all look into, or maybe you know.
Just so happens that Thomas Garner and Phebe Lampman I can confirm right now died on the same day. When I go to the Cemetery (After the snow clears) I am interested to see when Old Abe Lampman died.
Questions I have though, why was the Garner name dropped for the burial, but it continued with their children?
