Prince William and Kate announce their third royal baby’s name

By: Meaghan Wray

Royal watchers have been beside themselves with excitement since Prince William and Duchess Kate welcomed their third baby into the royal fold – and now they finally know what to call him! Kensington Palace confirmed the exciting news on Friday (April 27) via Twitter, writing: “The Duke and Duchess of Cambridge are delighted to announce that they have named their son Louis Arthur Charles. The baby will be known as His Royal Highness Prince Louis of Cambridge.”

The name may surprise fans of the Cambridges, as many were expecting his first name to be Arthur, given its strong royal ties as one of Prince Charles and William’s middle names. But Louis has a great deal of significance, too. It’s very likely a tribute to his great-grandfather’s great-uncle, Earl Mountbatten, who was killed in 1979 by the IRA. The name, which is of French and German origin and means ‘renowned warrior,’ is one of William and Prince George’s middle names.

Unlike with Prince George and Princess Charlotte, whose names were announced two days after their births, the Duke and Duchess waited four days with little Louis. But this isn’t the longest royal fans have waited to find out the big news. Princess Diana and Charles kept fans waiting a week before announcing William’s name, while, the Queen and Prince Philip kept Charles’ name on lock for an entire month!

Not a detail goes untouched for the British Royal Family – every name serves the purpose of commemorating someone within their family. Their eldest child Prince George Alexander Louis of Cambridge was named after Her Majesty’s father, King George VI, while his middle name is likely to have been picked to honour the Queen’s middle name, Alexandra. Their middle child, Princess Charlotte Elizabeth Diana, was named after the feminine form of Charles. Elizabeth and Diana are, of course, nods to the Queen of England and William’s late mother, the Princess of Wales.
