Opposite Sides of the Track

I really enjoy a good story in which the hero and heroine fall in love despite differences in class or financial status. If they have to defy family, friends, or society to remain together, it just makes the story even more interesting. I am only listing those stories in which the class difference was a fairly significant part of the story. In addition, I am not including those stories in which a "lower class" character suddenly becomes a lost member of the aristocracy or is otherwise made a more palatable match.
