The Royal Family is filled with members who are lucky to get fancy titles bestowed upon them, including the likes of HRH, dukedoms and honorary ranks.
However, not everyone is able to become a Duke or Duchess meaning many relatives who are further down the Queen’s line of succession must use a normal surname just like everyone else.
Many of the youngsters in the family, such as Prince George, Princess Charlotte and Prince Louis use their parents’ ‘Cambridge’ title as their surname. Their cousins Archie and Lilibet use the royal family’s ‘official’ last name – Mountbatten-Windsor.
It didn’t appear on an official document until 1973, but the complicated story behind the name dates all the way back to 1952, reports The Mirror.
Before marrying The Queen and becoming the Duke of Edinburgh, Philip’s official title was Prince Philip of Greece and Denmark of the House of Schleswig-Holstein-Sonderburg-Glücksburg.
However, his name wasn’t considered to be neutral enough when marrying the Queen so he adopted the name Mountbatten after his grandparents.
