Ophelia Snape

Ophelia Snape was adopted by the Potions professor after her parents were killed by You-Know-Who. She survived by hiding in her nursery and when Snape showed up, he left the baby Harry and took the three-year-old Ophelia with her. When her brother begins her years at Hogwarts, she gets to know him while falling for the control-freak Weasley, Percy.
