A royal baby usually gets at least three given names. For example, little Prince George is George Alexander Louis. Earlier generations, including Prince William and Prince Charles, were bestowed with four names. While royal rebels Meghan and Harry decided that Archie would have two given names, Archie and Harrison, they did ensure he had a double-barrelled surname: Mountbatten-Windsor. The Mountbatten is in tribute to the little boy’s great-grandfather, Prince Phillip.
