Send a message to the person who requested a photo of the grave monument of John Duncalf with the following comment:
I have been conducting a one-name study of the surname Duncalf (my maiden name) for almost 30 years and would be very grateful to receive images of the Duncalf gravestones. Should I request them one at a time? Unfortunately I am not able to help this project due to the fact that I spend most of my time working for the Lincolnshire Family History Society.
