The Royal Baby Boy’s Name Revealed!

Prince William and Kate Middleton have revealed the name they’ve chosen for their baby boy.

“The Duke and Duchess of Cambridge are delighted to announce that they have named their son Louis Arthur Charles,” Kensington Palace said in a statement Friday. “The baby will be known as His Royal Highness Prince Louis of Cambridge.”

Louis (pronounced “LU-EE”) means “renowned warrior” in French, and is likely a tribute to Prince Philip, whose grandfather was Prince Louis Alexander of Battenberg. Louis is also part of Prince William’s full name of William Arthur Philip Louis and Prince George’s full name of George Alexander Louis. The name holds great meaning to William’s own father, Prince Charles, whose beloved great-uncle and mentor, Earl Louis Mountbatten, was assassinated by the IRA in 1979.

The royal baby’s middle names of Charles and Arthur also hold special meaning. Charles, of course, is in honor of the baby boy’s grandfather, Prince Charles. And the name Arthur is a family tradition. Both dad William and grandfather Charles have it as a middle name. Arthur was also the name of Queen Victoria’s third son (and seventh child) and was said to be her favorite child.
