Send a message to the person who requested a photo of the grave monument of Thomas William Bell with the following comment:
I think my great grandfather, Joshua Henry Bell, was Thomas William Bell's twin brother. He moved to Byers Green and Todhills near Willington. I know several of the other Bells in your list are related and wondered if any relatives still lived nearby who may have photos. I live in County Durham and did visit the area with my mother when I was researching my family tree about 10 years ago.
