Firstly the most prominent character who shown pride should be Darcy. Since the introduction of his character, he was thought to be proud and arrogant by the others. Besides Darcy, Lady Catherine was also proud due to her high social statues.
In Jane Austen's "Pride and Prejudice," Elizabeth Bennet thinks that Lady De Bourgh is a bit nosey and intrusive, but deals with her good-heartedly. That is until the Lady Catherine tries to persuade her to back off of Mr. Darcy.
