LONDON, May 8 (Xinhua) -- Buckingham Palace announced Wednesday that the Duke and Duchess of Sussex have named their newborn son Archie Harrison Mountbatten-Windsor.

The couple presented the baby to the world, with Meghan declaring: "It's magic, it's pretty amazing. I have the two best guys in the world so I'm really happy."

Speaking in St George's Hall at Windsor Castle as her husband held their two-day-old child, Meghan added: "He has the sweetest temperament, he's really calm."

The baby could have become Earl of Dumbarton, or Lord Archie Mountbatten-Windsor, according to the royal family tradition. But Harry and Meghan have chosen not to use a title for their first born.

Archie, a German in origin, means "genuine", "bold" and "brave".

The baby boy, born Monday, is the Queen's eighth great-grandchild and the seventh in line to the throne.
