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.
