We don't really know much about Mandy, just that she was a Ravenclaw in Harry's year. But I'm writing a fic on her experience at Hogwarts, so I've got a few questions.
What is her full name? Mandy is commonly a nickname for Amanda, but also for Miranda and Melinda.(One of my friends suggested Mandaria or Mandarina.) Could Mandy also be a given name?
Did she have any friends in her year? I think that the only other Ravenclaw girls in Harry's year are Lisa Turpin and Padma Patil. Would she have befriended them? There are two invisible girls in her dorm, so maybe she could have been friends with one of those?
Is she halfblood? On Harry Potter and Me, JKR said that she was. I thought of the idea that maybe her father was a wizard who turned down the opportunity to be trained, and her mother was muggle. Would that make any sense?
Does she have any other family? When I first planned this out, she was the youngest out of four sisters; Maria, Virginia, Tamara, and Katherine. By the time she was eleven, Maria was married and out of the house.
