Archie, of course, is a shortened version of the name Archibald, meaning genuine and bold or brave. Archibald Campbell, 9th Earl of Argyll of Scotland was also an ancestor of Princess Diana’s. Using the nickname as a first name gives it a more casual, American vibe — while the baby’s middle name, Harrison, originated in the Middle Ages as a patronymic meaning “son of Henry” or “son of Harry.”
The surname Mountbatten-Windsor, meanwhile, belongs to all the children and descendants of Queen Elizabeth and Prince Philip.
"The Duke and Duchess of Sussex are pleased to announce they have named their first born child: Archie Harrison Mountbatten-Windsor," a statement read.
"This afternoon, Their Royal Highnesses introduced Her Majesty The Queen to her eighth great-grandchild at Windsor Castle. The Duke of Edinburgh and The Duchess' mother was also present for the special occasion."
