I name the files for the stone and I happened to remember it was 1796. Did a search and found it. I forgot the Elnathan Davis name so that would not have helped me.
I also type the cords in a text file along with every stone I find. So if I have the cords I do a search and the text file shows up. I go to the folder and the photo's are there. It works well as long as I have a memory. Once that goes this system stops working. I feel sorry for whoever acquires my files when I am gone.
