Prince Harry and Meghan Markle on Wednesday, announced the name of their royal baby. Baby Sussex, a boy, was born on Tuesday.
The Duke and Duchess of Sussex had earlier in the day unveiled their son to the world, about 24 hours after his birth.
The royal couple named the baby Archie Harrison Mountbatten-Windsor.
The name is believed to have little precedent within the modern British royal family.
The couple shared the news on Instagram with an image of Queen Elizabeth and the Duke of Edinburgh, meeting their newest great-grandchild.
