Who is Miss Mabel Chiltern from the play, An Ideal Husband?

Mabel Chiltern has her eye on Lord Goring as a husband, and the two become engaged in the play's last act. She is the sister of Robert Chiltern. She is pretty, intelligent, and pert, and she is as witty as Lady Basildon and Mrs. Marchmont are. Knowing that Lord Goring is the man for her, Mabel Chiltern is waiting gracefully and humorously, albeit somewhat impatiently, for him to realize that she is the perfect woman for him.
