I have just seen your message asking for help with a poem on a gravestone. Since all the responses were of no help, I think I can help point you in the right direction.
Go to the website FindAGrave.com and you will need to enter the information on the grave. if you have a name for the cemetery that would be good, but it sounds like you do not. That's ok, you can still enter your information. You should post the photograph and perhaps list the cemetery name using the name of your family member or the original owner of the property when the first grave was put there since it's on private property.
The website also has a group of volunteers all over the country who take requested photographs of gravestones. Once you set up the memorial page for your ancestor you can enter your photograph request. There is no guarantee that it will be done anytime soon but it's a start.
If you can email an image direct to me I may be able to enhance it a bit for you. It does look like the etching is still in fairly good condition. My email address is

Good Luck!
