Send a message to the person who requested a photo of the grave monument of Jane Johnson with the following comment:
William Johnson is my ancestor. I have paperwork evidence for this. I do not publish my family tree online. I do contact possible relatives through family history societies and personal messaging through Ancestry. Last week I visited Caistor and I could not find this gravestone. Before visiting the churchyard I looked at the plan at Lincolnshire Archives. In your book at the Archives I found brilliant information about the gravestone of Gorbutt Johnson, William's son under the Ff section. Thanks for all your great work.
