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.”
The names Louis, Arthur and Charles have significance within the royal family. Louis was the name of Prince Phillip’s grandfather, Prince Louis Alexander of Battenberg, as well as Prince Charles’ great-uncle Earl Louis Mountbatten, who was assassinated by the IRA in 1979. Louis is also a middle name for both Prince William and Prince George.
Louis Arthur Charles is the third child for the Duke and Duchess of Cambridge, who welcomed a son, Prince George, in 2013 and a daughter, Princess Charlotte, in 2015.
The name Arthur, which means “bear” in Celtic, is also rooted in mythology. King Arthur is a legendary figure who was head of the kingdom Camelot and the Knights of the Round Table in medieval times.
“We are both so pleased at the news,” Charles said in a statement. “It is a great joy to have another grandchild, the only trouble is I don’t know how I am going to keep up with them.”
Queen Elizabeth celebrated the latest addition to her family with a quick horseback ride through the grounds of Windsor Castle, where she is staying with husband Prince Philip, who is still recovering from hip surgery.
Prince William and Kate waited four days before revealing their new baby’s name, that didn’t keep British oddsmakers from making predictions (Albert and Arthur were early favorites). William also teased his son’s name as he left the hospital. “You’ll find out soon enough,” he said with a smile.
