Early Masonic Gravestones

One of my ongoing projects of the last few years has been locating and documenting early Masonic gravestones. My focus is in the period before many lodges "went dark" in the 1830s-1850s during a time of strong anti-Masonic sentiment, though if there is a very ornate or otherwise interesting gravestone from after that time I am also interested in seeing it!

For my project I have created a Google Map of all of the Masonic gravestones I've found so far on Find a Grave.
