Send a message to the person who requested a photo of the grave monument of Robert Welch with the following comment:
I believe Robert and Lucy Welch are my 3xGreat Grandparents. I live in East Surrey and don't drive so it may be a while before I get the opportunity to visit the grave and to have a photo in the meantime would be very welcome. I do parish record look-ups and rarely get a thank you either so I know how you feel but you will definitely get a thank you from me!
