6 – Number grandchild that Eugenie is for the queen. Eugenie has a close relationship with her grandmother, and while William and Harry always refer to her as "the queen" or "my grandmother" in interviews, Eugenie always refers to her simply as "granny."
8 – Number in line to the throne that Eugenie currently is. When she was born, she was sixth (behind Charles, William, Harry, her father Prince Andrew, and sister Beatrice), but she's gone down to number eight following the births of Prince George and Princess Charlotte, and will drop to number nine after the birth of the new Cambridge baby in the Spring.
