The Duke and Duchess of Sussex have named their baby son Archie Harrison Mountbatten-Windsor. The name Archie does not have any British royal connotations, but the name means ‘genuine’, ‘bold’, or ‘brave’. Harrison is also a totally new name for the royal family: it was originally used as a surname meaning ‘son of Harry’. As the first-born son of a duke, Archie could have assumed the title of Earl of Dumbarton, but he will instead simply be known as Master Archie.
