Vickie, I know where the Erwin "Plantation" Cemetery is. I was there last Memorial day (2010). It is a beautiful old cemetery. I do agree that John L and Elizabeth are buried there and if I knew exactly where I would erect a stone for them. However, no one seems to know where. There is an area of the cemetery that has new burials and a section that has old stones, as in rocks. Although the family seems to have been affluent, John L died during the Civil War and things changed, especially finances. It could be that the able-bodied slaves they had left them and Elizabeth no longer had discretionary income. They did have slaves (old women) who stayed for years. The cemetery is in an area of Carter Co called Smokey Valley just off Route 2. I would be glad to show you when you're here if our schedules meshed. The reason they are not listed on any cemetery survey is because they have no stones. It has been pretty well documented by family lore that that is where they are buried. Janice
