We finally have a royal baby name! Prince Harry and Meghan Markle announced their newborn son's name, and it's Archie Harrison Mountbatten-Windsor.
But why not "Sussex" as the last name?
Queen Elizabeth, Prince Philip and Prince Charles all carry the last name Mountbatten-Windsor (a combination of Elizabeth and Philip’s last names). For any non Crown fans in the room, that name is passed on to all the male-line descendants of the queen and Duke of Edinburgh, except for those with royal titles and styles.
However, Kate Middleton and Prince William, Duke and Duchess of Cambridge, have opted to use their royal title of Cambridge as their children’s surnames instead of Mountbatten-Windsor (probably in order to blend in a tiny bit more into normal society). In school, Prince George is simply George Cambridge, and the same goes for Charlotte and Louis.
