Who is Maggie MacDonald from Rebellion and what is their importance?

Maggie MacDonald is Serena's childhood friend. She is first known to the MacGregors, particularly Coll, as a pesky young nuisance of a girl. However, she is in love with Coll even as a girl. When she pays a visit to the MacGregors, Ian MacGregor plans a ball as a ruse to gather clan members who are organizing for the rebellion. Maggie is now eighteen and has blossomed into a beautiful, graceful young woman. She has her sights set for Coll and he is helplessly drawn to her. Maggie climbs a ladder and feigns a fall in front of Coll, who quickly helps her treat her injuries and promptly asks her to marry him. She is unabashed about being dishonest, but feels it is an innocent way to get Coll to do what he wants to do. Maggie is tiny and has an extremely difficult two-day labor giving birth to a breech baby. They both come close to death, but with Gwen MacGregor's help, they survive and eventually thrive. Maggie and Coll decide to stay in Scotland when Serena and Brigham leave for the New World.
