Prince Archie of Sussex
As a grandson of King Charles III, Archie is sixth in the line of succession to the British throne. At the time of his birth, he normally would be entitled to use his Prince Harry's senior subsidiary title, Earl of Dumbarton, as a courtesy. However, it was reported that the Duke and Duchess decided that he would be styled as Master Archie Harrison Mountbatten-Windsor, as they wanted him to grow up as a private citizen.
