Althought it's more about fictional characters from movies.
Frodo is definitely an INFP though, and Anne Shirley is either an INFP or eNFP. She's extremely talkative, but you can't deny she lives in her head most of the time. Her imagination is everything for her and she's happy even if she doesn't share it with anyone. Also, she certainly displays tons of Fi and Ne, and Marilla Cuthbert seems to be created to be her exact opposite - an ESTJ.
