Were any of the main characters in Pride and Prejudice (Mr. Darcy, Mr. Bingley, Lady Catherine de Bourgh) more than gentry? Did any of them belong to the peerage?
Was there any formal difference in the rank between Mr. Darcy and Mr. Bennet? I guess not, based on what Elizabeth says:
He is a gentleman; I am a gentleman's daughter; so far we are equal.
So was the superiority felt and expressed by Mr. Darcy and Lady Catherine based only on the difference in the scale of property?
BTW, was any relevant Jane Austen character a British peer?
N.B.
I accepted @alexg's answer, because the website unfortunately allows us to accept only one. However I'd like to acknowledge the @verbose's answer as equally useful.
