Diana has two older sisters. Sarah is the oldest and she actually introduced her little sister to Prince Charles back in the day. Sarah first dated the heir to the throne herself, but their relationship did not last very long. Soon after, Diana became the woman at his side.

Princess Diana's sister Jane also had a hand in her relationship with Charles. Jane was allegedly the one who convinced Charles to take his relationship with Diana public by taking her to a ball. Both sisters were part of the royal life at the palace and their children actually grew up with Prince William and Prince Harry.
