Hi Everyone
I have been doing this type of thing for over five years for my own family tree with some success. And I have FAILED Especialy if the grave yard has been built over sold or the headstones have been taken down for health and saftey reasons which seems to be the case in the u.k rather than pay for the upkeep.I now take my Sat nav with me and note the longdetude and latatude position of the grave-headstone and either note it on the back of the photo or keep a log and it will not be lost again and I am sure in the future some one in my family will be pleased that i did .ITS JUST A THOUGHT!!!
