Meet Prince Louis Arthur Charles! The son of Kate Middleton and Prince William has been named, according to an announcement from Kensington Palace. (And yes, people have been sharing their hilarious reactions.)
Weighing 8 pounds and 7 ounces, the baby was born Monday at St. Mary’s Hospital in London and introduced to the world only hours later, when the royal couple stood outside for a worldwide photo op.
Though the name Louis is traditionally associated with French royalty, it does have an interesting British royal connection. Louis VIII of France claimed the title of King of England from 1216 to 1217, though he was never formally crowned and ultimately surrendered the dubious claim. Both Louis and Arthur are part of Prince William’s full name: William Arthur Philip Louis. Meanwhile, big brother Prince George is George Alexander Louis.
Arthur was a popular choice from the start — according to Vogue, Prince Charles wanted to name his son Arthur but Diana, Princess of Wales, nixed the idea.
And that leaves Charles, which is, of course, the name of the newborn’s paternal grandfather, who is next in line for the throne. Charles is also one of Prince Harry’s middle names.
Over the course of Middleton’s pregnancy, the world was split over whether the royal couple was expecting a boy or girl. Mary, Alice, Albert, and Arthur were top guesses among British bookkeepers.
For a while, Albert was a main pick. According to Today, Queen Victoria was so in love with her husband, Albert, that she declared all her “male English descendants” would bear his name and pressured her children to use it. Her persistence paid off — Albert is also one of Prince Harry and Prince Andrew’s middle names.
As for girl names, Alice was a big bet because it’s the name of William’s great-grandmother (Prince Philip’s mother) and Queen Elizabeth’s aunt, the Duchess of Gloucester. And it was in the rotation before the birth of Will and Kate’s 2-year-old daughter, Princess Charlotte.
Mary was also a legit possibility — it’s the middle name of Queen Elizabeth and her grandmother, and of the first queen to rule: Mary I, aka Bloody Mary, for her tendency to burn detractors at the stake.
On a few occasions the royal couple had seemingly dropped hints about the sex of their unborn baby. For example, the U.K. Mirror reported that at a football game in April, William suggested that he wanted to name the baby after athlete Jack Grealish, saying, “I’m going to insist the baby is called Jack,” adding “or Jackie.” And earlier in her pregnancy, when Middleton stepped out wearing a $2,100 hot pink Mulberry coat (which she wore twice while pregnant with Princess Charlotte), fans bet on a girl.
According to E!, however, the royal couple chose to remain in the dark about the sex, so they most likely bestowed the name at the last minute. “William and Kate don’t know the sex of the baby so they’re rather looking forward to finding out,” a source told the site predelivery. “It’s very difficult to be totally prepared when you don’t know if it’s going to be a boy or a girl.”
