There are many rural out of the way cemeteries where people come around and write down the names on the tombstones. I lived near one and there was always someone with a note pad going around writing this information down. They usually had out of state plates on their vehicle.
Some of that is legitimate genealogy research.
That might have been me, some years ago, loopkong up my great-grandfathers and all their families that lived in New York but were buried just over the line in a small rural cemetery in Pennsylvania. There were even Revolutionary War veteran's graves there.
I lived in Delaware then.
If you want a great number of deceased names, just go to the LDS records.
