Researching Canadian Graves
There are three websites that are helpful when researching Canadian graves/headstones that I've learned about and have had good things said about them: Canadian Headstones Photo Project, the Canadian Gravemarker Gallery, and CanadaGenWeb's Cemetery Project. You definitely need to explore each of them to see which one might be most useful to you. I'm also certain that if you have headstone photos to share, each would be pleased to have your submission.
Now, where did I put those photos from Galt (Cambridge, Ontario)?
