George, Charlotte, and … Louis. A name has finally been bestowed upon the youngest child of Prince William and Kate Middleton, reports People, ending four days of suspense since the baby's birth on whether the couple would go traditional or adventurous. Louis Arthur Charles is the boy's full name, per a Kensington Palace statement, and he'll go by "His Royal Highness Prince Louis of Cambridge"— a "surprise choice" that "confounded expectations," per CNN. Louis means "renowned warrior" in French, and although it's not a traditional Brit name, it appears to have more than one tie to the royal family itself: Prince Philip's grandfather was named Prince Louis Alexander of Battenberg, Prince Charles had a favorite uncle named Earl Louis Mountbatten, and Louis is also part of the names of both the new baby's father (William Arthur Philip Louis) and brother (George Alexander Louis).
As for the infant's middle names: Charles is obviously a shout-out to the baby's grandfather, and both Prince William and Prince Charles boast Arthur as part of their extended names. The three-time grandpa, for one, is looking forward to having Louis in the mix. "It is a great joy to have another grandchild," Prince Charles said in a statement, per People. "The only trouble is I don't know how I am going to keep up with them." What appears to still be a source of confusion: whether to pronounce the baby's name "Loo-ee" (as CNN notes) or "Loo-is" (as the Sun claims). However you say it, the kid is fifth in line to the throne. (Read more royal baby stories.)
