It's seems to have become common wisdom that Huck Finn was modeled on
one Tom Blankenship.  Yet, in Twain's autobiography (Kiskis, 1990 pg
191) Twain states he was actually Frank F., although the note therein
refers back to Tom.  Who was this Frank F.?  Was he the actual son of
Jimmy Finn?  Later in the same dictation it is Frank F that became a
Justice of the Peace.
