I'm Miri and I have a few characters that might be workable. And, because I'm lazy, I'm going to post them each on their OWN IDs.

So, this ID is Caitlin Vennegoor of Hesselink. She's a fourth year Gryffindor and can be a bit of a holier-than-thou sort of girl. She's Muggleborn and can't abide purebloods. She rather cuts them all in the same cloth and doesn't really believe a pureblood can ever be anything but a pureblood. She's been developing interests in the opposite sex as of late, as well.
