You may be right on this point. Like Kinbote, I am lacking a proper text to consult right now!
I hope there's no amusement park.
I stand corrected. But what might those two names have been? Anagram experts?
The full quotation about "Sutton" is "This is a recombination of letters taken from two names, one beginning in 'Sut,' the other ending in 'ton.'" I've long suspected the names were "Sutcliff" and "Clifton", but there may be other possibilities, even equally neat ones.
