Jerry, As you know, all bits and pieces have to be gathered in case they turn out to be useful! I came across, but didn't have time to do more than skim, a fairly detailed history of the 15 at Kew; some time a bit later this year I'll go back and read it seriously; it looks as if George may have been picked up by Borlum (I don't really believe this name!) after his retreat from Edinburgh.
