My relatives are in a cemetery where the gravestones are losing their readability. The hamlet office does not know who is buried in some of the graves anymore and they have asked our family for help. We only realized the extent of the deterioration of the cemetery after Grandma died and we realized that there are no oldtimers left in the town anymore to care for the graves (she was covered in weeds). My parents spent days mowing, hauling good soil, sewing grass, and replacing broken vases for the clan.
What steps can I take to track down the (now hidden) members of the cemetery? And are there any preservation techniques for headstones?
