Oddly, there doesn't seem to be a specific thread dedicated to this book, although of course the type of Atticus has been discussed a lot.

The types of the children I couldn't really care less about - they're rather boring. I suppose Scout could be the same type as Huckleberry Finn.

The type of Boo Radley I am more interested in, even though he's probably not really an ideal person to type. I've always liked to consider him EII.

The book is a Delta book on the whole, yes? Harper Lee herself may well be an EII, although there is little to go on.

The types of Calpurnia and minor characters like Aunt Alexandra, Uncle Jack etc. might be possible to be derived (it's awhile since I watched or read this) - but with Bob Ewell it might be best not to broach the subject.
