Name for Slytherin heroine OC, in Harry Potter fanfiction?

I'm writing a fanfiction, featuring a Slytherin girl as the main character. She's very quiet, calculating, and shrewd. Dark hair, pale skin, dark eyes, not beautiful but not ugly. I'm looking for any name (first and last) that stands out, but I don't want a Mary-Sue style name like "Raven Estella Serpentia." It can be a common name, but something individualist, not like "Martha" which is kind of simple and boring. Thank you!
