Ledger stones are the large, rectangular flat slabs that you sometimes see covering graves in cemeteries. The information about the deceased is then written across the top. Ledger stones are necessarily popular, but they are by no means unheard of here in Ohio.
Sidney Guy Sea of Chicago ended up beneath a ledger stone in Lake View Cemetery, Cleveland.
This one is for George Philip Hart.
Louis Harvey Winrh has a ledger stone as well.
