It all makes sense!
The royals are so known by their royal titles that we often forget that they actually have surnames – given that the Queen doesn’t need a passport, she hardly needs a surname.
But they do have an official surname – Mountbatten-Windsor – a combination of Queen Elizabeth and Prince Philip’s family names, something that any fans of The Crown will know.
Unlike most families however this surname won’t be carried down to Prince Harry and Prince William’s own children, with royals often going by the name of their family Dukedom – making it easier to tell them apart, and letting them blend into normal life.
The Duke and Duchess of Cambridge have taken ‘Cambridge’ as their surname, enrolling their children to school under the moniker, to ensure that they live a normal life, without their school friends having to call them HRH.
This is something that Prince Harry and Meghan Markle will undoubtedly follow, giving their future baby the surname ‘Sussex’, a nod to their title, the Duke and Duchess of Sussex.
The tradition is still relatively recent, started by Prince Charles and Princess Diana who gave Princes William and Harry the surname ‘Wales’, taking from their title as the Prince and Princess of Wales.
So Harry and Wills may still share the same surname still, but their children won’t.
Royals – so confusing!
