Stephenson:Neal:Quicksilver:15:Daniel Waterhouse (Neal Stephenson)

From the Quicksilver Metaweb.

Waterhouse is a reasonably common English name. The Waterhouses, both here and in Cryptonomicon, are totally fictitious and bear no relationship whatsoever to any real people named Waterhouse anywhere in the world. Daniel Waterhouse has one or two things in common with a John Wickins who was Newton's roommate at Cambridge, but beyond that he is completely fictitious (as are the other Waterhouses) and there is no point trying to search historical documents for anyone of that name.
