How old do Ты think Madellaine is?

Madellaine is from The Hunchback of Notre Dame 2, not the most loved Дисней movie, and I'm wondering how old she might be.
Considering that Quasimodo (her Любовь intrest) would be about 25-26 in the movie (sequel) I don't think she'd be any younger than 18-19. She's also got a diverse personality, making her sometimes serious and other times childish. Any ideas?
