That's her name in the credits of the show, and that's what she was introduced as.

If she really is a Frobisher-Smythe, that doesn't mean she has to have that last name. Frobisher-Smythe could have been her mother's maiden name and her father had the last name Rush. Or simply neither of her parents used that last name.
