Next time you're out that way, stop in and visit at the city clerk ... bet there's a wealth of information to be had on that cemetery.
We did that...talked to someone at City Hall. That's how we found out the stuff burned up.
:-(
All this happened so very long ago...just after the turn of the century. My grandmother was just twelve, she was 42 when she had my mom. She died when she was 86 years old...about 25 years ago.
My mom has traced our roots back to the 1500s...we've visited many a grave. But we can't find these. The townsfolk literally went into the house and dispersed the property amongst themselves, along with the kids. Can you imagine?
An uncle eventually came and got several of the kids, but one couple had taken the baby and left town.
We know this is the right cemetery, my uncle took my mom years ago (he's been dead many years too) and showed it to her, so when I took her she recognized it. But if they ever had markers, they were likely wood and long gone now. And I'm sure they were just buried in wooden boxes. Likely someone else is buried over them.
