"I want to go now!"
Lily Luna Potter, unhappy that she has to wait another two years before going to Hogwarts (DH/e)
Youngest child and only daughter of Harry and Ginny Potter. Like her mother twenty-eight years earlier, Lily was envious as she stood on Platform 9 ¾, watching her older brothers go off to Hogwarts (DH/e).
Lily Luna Potter is very supportive of Teddy Lupin's relationship with her cousin, Victoire Weasley (DH/e).
Lily Luna Potter is presumably named after her grandmother and Luna Lovegood. Lilies represent purity and "luna" means "moon" and suggests both unearthliness and eccentricity. It is not clear whether these names are reflective of her own personality or not.
