Who is madame joanna in Catherine Called Birdy?

Madame Joanna is the cousin of the King. Madame Joanna told fortunes to Catherine. This is what MY book says:

Madame Joanna is a hundred years old, gray and puny, smaller even than Robin Smallbone's sister, who is not yet eight. Her face is wrinkled and brown and covered with gray hairs, her eyes are round and red, and she is missing all her teeth but the front two on top.

It's funny, because Catherine thought she was gonna be beautiful....but CLEARLY she is not.
