I got in touch with the cemetery people regarding getting my great-great-uncle listed as being buried with his family despite having no direct evidence that he was.
I tried for years to get the person in charge to answer me and failed. Got in touch with that person's parent, whose husband used to be the main person.
So the woman agreed to let me send her my documents. She did read them, she thought it was very likely that he was buried there, and I said I wanted him officially listed as also being buried there with several siblings, some nieces and his parents. It's been a few months.
I have heard nothing since.
