Margo is the oldest of three little girls, sisters in fact, who have lived for most of their lives in Miss Hattie's dismal orphanage, forced to sell cookies for her...and without seeing any benefit from the profits.  Margo is a very smart and sophisticated young lady, and takes it upon herself to protect her younger sisters and be their leader.  She's also quite outspoken, and not afraid to take a stand when she feels it necessary.

Margo and her two younger sisters, Edith and Agnes, regularly attend dance classes and recitals, and have a great deal of pride in it.
