Lilibet’s birth announcement, shared on the Archewell Foundation website, said that she was named after Queen Elizabeth’s family nickname while her middle name Duke and Duchess of Sussex as the last name for their children. PEOPLE understands that Sussex is their family surname. Using their titles as their children’s last names follows the tradition historically used by members of the royal family.
