Don't Belong?

Y/N somehow appears at the gates of Hogwarts amongst the other children despite the fact that she grew up with muggles. She is a first year who arrives the same time Harry Potter, otherwise known as the boy who lived, does. There's just a few problems. She was muggle-born right? So, why was she? Who the hell is the boy who lived? And WHY was everyone starring at her like that?!
