Hi Richie,
I've had a good read of Paul Slade's website now and seen the results of both his and David Fowler's thorough researches. Whilst there is a lot of speculation there are also a few good clinchers like the existence of the ship and Stewart's name and the death of Bilston. I think their theories very plausible. I have a lot of respect for David Fowler's work. He does his own research and unlike other so-called scholars doesn't blindly reproduce others' statements. The only regret I have about Fowler is he restricted his researches upto 1800 and didn't go beyond.
