I also like visiting local museums and historical sites.
Last year, I visited the Frankfort Historical Society in W. Frankfort, Illinois, and wandered up to their genealogy room. Some of the volunteers are putting together a book of all the known cemeteries in Franklin County, Illinois, and listing the people buried in them.
Because so many grave markers can no longer be read, they are relying on old records or family documents that people donate or let them copy.
Besides the known cemeteries, people who visit the museum tell them about old cemeteries that are now on private land, or graves they remember being in fields or in overgrown wooded areas.
Graves become lost because some old markers were made of wood and have since rotted, and old stones often sink into the land over time, becoming covered in leaves and briars.
This is where grave dowsing comes in handy. Several of the volunteers at the historical society knew how to dowse for graves and did so when they thought bodies should be in a certain area, but could find no markers.
The photos below are of old cemeteries and most likely there are graves without markers in the bare areas.
