Prince William and Kate Middleton has named their new royal baby, Louis Arthur Charles.
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.
