This is so far down the comments that it won’t be read by many, but here goes:
I have two Civil War veteran great grandfathers buried in a Methodist cemetery near Pittsburgh, PA (along with their spouses and a few of their children - all who died in 1915 or earlier). The cemetery doesn’t have a lot of headstones there. Reason: The 1918 flu epidemic.
After the flu started its killing spree, lots of people didn’t have the money to pay for a lot, so they went to plan “B” - midnight burials. When I asked the church why the place was not better used, the answer was “even though there were no headstones, wherever we tried we dug up human bones; most all of them without a coffin”. Gulp!
Sad, but interesting!...................
