We seem to have got away from 
living  famous people, I'm the only  famous person (living) any of my relations have.
But famous dead people abound. 
There is James Bonnin who built half of London in the early 1800's.
Then there's Captain John Cooper who was a whaling captain. 
Lady Blackwood. (possibly 3rd mate on the infamous attack of the 
Lady Rowena  on a Japanese whaling village, 1830)
There must be more, but I just can't find them!  
  
  
Cheers,
Leonie.
