Matilda INFP - no way. She's interested in theories rather than mystic connections. When she realised she had this telekinetic abilities, the first thing she wanted to do is experiment to see what the limits of her abilities were. And she isn't that spontaneous - on the contrary, whenever she has an idea she will make a coherent plan first. INTJ seems okay... though she has some extravert tendencies (but who hasn't?).
Anne of Green Gables is quite the chatterbox. I've skimmed the pages again... I see some ENFP characteristics too. But if you look at the functions... it's Ne at the service of Fi, not vice versa. I'm happy to find an INFP example who's not this seclused.
George (of George's Marvelous Medicine) INTP - yes. And his father, Mr. Kranky, is an ENTP! (Why oh why didn't they think of keeping some of that medicine to let it be tested chemically?!). What type would that awful grandma be? I'll reread the book!
Before I add Mrs. Wormwood and Miss Honey, I'll reread that book too... On first sight, ESTJ and INFJ seem right, though. (Yay, an INFJ! I lack examples of that one!)
So far, I've got now:

some INFJs, ISFJs and ISTJs... (I'm going to check Mrs. Honey)
a nasty ESFJ, ISTP, ESFP, ISFP, ENTP, INTP and INFP (I've created a very dark INFP on the verge of destroying the world, but that one isn't fit for publication yet.)
