Stephenson:Neal:Quicksilver:21:John Comstock and Thomas More Anglesey (Neal Stephenson)

From the Quicksilver Metaweb.

These names are both factitious and the characters both fictional. Don't bother Googling them. John Comstock has a few things in common with John Evelyn (an early Royal Society figure and author of a great Diary) and a few other things in common with the Earl of Clarendon. Thomas More Anglesey is not based that directly on any historical figures, but stands in for a lot of Francophilic crypto-Catholic courtiers who were thick on the ground in those days.
