You surely are correct that sometimes the information is written on sheets of paper curving around the edges. That's exactly how I found information about William Jackson Clayton (John Anderson Clayton's son) and the name and death of his first wife. I never even knew he existed until I found that. He was also a confederate soldier. He died in February 1908 and I have found no descendants in my searching.
It's been awhile since I checked cemeteries on the internet, so will do that again.
Thank you.
