The first name of Don and Betty Draper’s eldest child is Sally.
Sally Beth Draper is the oldest of Don and Betty’s three children; her younger brothers are Bobby and Gene. She is portrayed by Kiernan Shipka, initially as a recurring character before becoming a major figure in the later seasons.
Sally’s sixth birthday is depicted in the third episode, “Marriage of Figaro,” which is set in May 1960. As the series advances through the 1960s, she becomes increasingly aware of her parents’ divorce, infidelity, emotional distance, and the rapidly changing world around her.
Viewers sometimes confuse Sally with other children connected to the series, including Tammy Campbell, Pete and Trudy Campbell’s daughter. Caroline is Roger Sterling’s secretary, while Stephanie is a different character entirely. Sally’s importance grows as the show shifts from Don’s professional life toward the consequences of his choices for his family.
