Hi - my name is Richard Jones. And I realise that this post is a few years old, but I thought I would try.
My mother was Rita Mary Sewell and my mothers father was William F Sewell. William F. Sewell's father was Frank Sewell who I believe is the brother of William Drake Sewell. I have this information in a file but unfortunately I have not figured out how to make the attach feature work on this bulletin board.
Also, Lord Sewell was actually (I think) "Lora Sewell", or nee "Laura Cooper" - who married a John Sewell in 1808. They had a daughter who was also called Lora.
I have most of this documented - assuming it is right on Ancestry.com
