Gary, as far as I know the only mine connection was with Arthur's wife Mary Mowll whose family were coal merchants /miners.
Thanks Tom, I had an e mail from a man re the Swedish connection a while ago.
The second link to Wiki is from my site about him. I was recently in Ramsgate at a cemetery photographing the graves of Arthur's parents. I have posted things on a few genealogy sites but nothing new of late do thought I thought I would have another try, you never know!
