Bridget O'Malley is the younger sister of Nellie O'Malley and the adopted sister of Samantha Parkington. Bridget is the middle of the three O'Malley sisters. She is seven in Samantha Learns a Lesson and has dark curly hair (though she is illustrated with light hair), grey eyes, and a high, flutey voice. She has a teddy bear named Fred and greatly loves stories, especially scary ones. Unlike Nellie, she and Jenny are easily adjusting to their new well-to-do-life; this is most likely due to their age. However, she does miss her parents and cries in her sleep about them. She and Jenny have a private tutor after being adopted.
