That's an interesting story! You should see if you can sketch him sometime and try to match him to any old family photos if you can! I was raised the same way about respecting graves. Sometimes I wonder about archaeological digs that produce old human bones. Do their spirits feel disturbed?
I haven't seen any ghosts in cemeteries, only flits of what might have been there. However. I was searching for a particular piece of statuary for a friend who wanted to use it for a CD cover (she was in a band) when something strange happened.
I knew it was a cemetery statue. We had both seen a photo of it and could see headstones in the background. I was checking every cemetery I could find and I had just come upon this old Catholic cemetery. It was trimmed up front, but just past the trees it was horribly overgrown. I pulled in and started walking around. I didn't see the statue, but I did see a pile of trash along the back wall. You know those marble urns that they used to put flowers in? Lots of them were in the pile.
I don't know what got into me, but I started taking the urns and matching the broken bases to their original graves. It took a period of several weeks even though it was a small cemetery. I managed to get most of them matched back up. The smaller the pile got, however, the more I began to notice the garbage was over old graves. Some of the graves no longer had headstones, but you could see the depressions. I moved the pile off of the graves and as I moved the last one I saw a grave stone with my family name on it! There was a picture of a very handsome man who died young in 1936. I think he was 23 or 24 when he died. He was no relative of mine that I knew, and I asked the family (it's an uncommon name, and our spelling was even more uncommon, so it was odd that he wasn't related), but while there were people with that exact name in the family, none of them would have been buried there, let alone in 1936.
I continued to go back to that cemetery every week and clean up the back part little at a time, and I always brought flowers to his grave. When I had to leave the area, I made one last stop to say goodbye and to apologize for not being able to finish my work. When I got there, the garbage pile was being loaded into the back of a truck, a crew was re-cementing the urns to their graves, and the back area was trimmed with someone looking at what I guess was an old map of the place.
It's hard to express what I felt. Relief? A sense of gratitude? I just know that when I pulled out of the gates for the last time, I had the sensation that my "work" there wasn't to clean up the graves so much as it was to bring attention to the deplorable condition of the cemetery.
