Send a message to the person who requested a photo of the grave monument of William Atkinson with the following comment:
My 3rd great grandparents names were William and Hannah. We don't know when they died or when they were married. This seems to fit the dates we are looking for. They spent most of their time in Lincolnshire, so I'm not sure if this is it or not, but I'm very grateful for all of the work you have done to provide this service!
