Who is Maureen Jellison from Lucifer's Hammer and what is their importance?

Maureen is the daughter of Senator Arthur Jellison. She is a beautiful young woman who hates the thought that she's the "princess" of Jellison's kingdom. She says that she feels like a prize to be won and that the man who wins her hand will become the new ruler of the "kingdom." Maureen has sex with Harvey before the comet strikes, but later can't decide whether that's truly where her heart lies.
