Hi Mick ,
Apologies for having two usernames - it can be confusing to me too !
The story of the Steward to the Duke of Bolton doesn't seem true . Humphrey's family can be traced in Ludgvan back to at least 1588 , but the 1st Duke of Bolton wasn't created until 1689 ! ( Charles Paulet )
Don't get me wrong - I would love to be linked to Humphrey Davy ( my mother is a Davey ); but I want it to be proven .
