Lamb's Tree, Two has a fantastic link today: http://newyorkgravestones.org/. They are trying to get all the tomb stones for New York state. Part of the Gravestones Photo Project (GPP), there are also sites available for Massachusetts, Oregon and Utah.
According to their site: "The mission of this project is to capture digital images of gravestones of our ancestors. As decades pass-- many stones are becoming harder, if not impossible, to read the inscriptions they originally contained.
By archiving the images, we can help save these important records and also assist researchers using this valuable resource."
I do not see any of my ancestors yet, so time to start editing my photos to their specifications and adding them. The specifications alone are worth visiting the site: http://www.sampubco.com/gpp/crop.htm.
I only wish that all the tombstone project sites would get together to form a comprehensive site, instead of having to check and add to all the known sites.
