Send a message to the person who requested a photo of the grave monument of Gulielmus Betts with the following comment:
I am working with a team researching the extended family of the Taylors of Ongar (non-conformist writers and artists in Georgian times) and their antecedents, many of whom were Dutch and Huguenot immigrants. The Betts family were an exception, being long established in Suffolk (we think - the image will help us check this). In return we can send you pdf's of several Wills by members of this family to share with others, and information on how to access a carefully researched family tree online
