With the death of Queen Elizabeth II, Charles instantly and automatically became king, taking the name King Charles III. Behind him in line for the throne is his eldest son, Prince William. Next are William’s three children: Prince George, Princess Charlotte and Prince Louis. (A change to royal succession rules in 2015 removed male bias.) Then comes Charles’s second son, Prince Harry — even though Harry gave up his royal job and moved to California. Harry’s children are next: Archie and Lilibet. At No. 8 is Prince Andrew, Charles’s brother, who is also no longer a working royal, though in Andrew’s case because of scandals. No. 9 is Andrew’s eldest daughter, Princess Beatrice. And No. 10 is Beatrice’s daughter, Sienna — who turned 1 on Sunday.
