Not arguing with you, but do you know where? I've been doing genealogy since 2008, including lots of checks on Ancestry, Family Search, FindAGrave and Billion Graves and I've never seen or heard of something like this.
It does look like it's a pretty old cemetery. Maybe it's somebody famous or infamous?
I did JUST think of a new meme involving Dracula, so you'll be seeing that one pretty soon.
