The cute Harry Potter connection to the royal baby’s name you may have missed

In case you haven't heard, the Prince William and Duchess Kate welcomed their third child this week.

The newest Prince was born on Monday, and fans of the royal family were ooh'd and ahh'd over the sweet photos of Kate, William and the newborn leaving the hospital. The only thing we hadn't found out by that point, though, was the name of the little one. But, after days of speculation, the proud parents confirmed their infant son's name on Friday morning: Prince Louis Arthur Charles. Kensington Palace confirmed the news, writing on social media:

"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 Weasley family from J.K. Rowling's Harry Potter series. And while we know that Prince William and Kate Middleton were unlikely to turn to some famous faces or even a series of books (no matter how magical it is), we still think it's quite sweet. Following the official announcement on Friday, the Pottermore Twitter account was quick to point out to the moniker's connection to the world of witchcraft and wizardry. https://twitter.com/pottermore/status/989823788962533376?ref_src=twsrc%5Etfw They said:

 "Louis Arthur Charles, you were named after three iconic Weasleys…"

Charles (or Charlie) is one of Ron's oldest brothers, the one who went to study dragons in Romania. And, as fans of the series are no doubt aware, Arthur was the name of Ron's father. As for Louis? That was the name of Fleur and Bill's youngest son. https://twitter.com/classygirl_/status/989839688323272704 https://twitter.com/Keet67/status/989838828016979971 https://twitter.com/leajmoreau/status/989827182477406209 https://twitter.com/travelingheidi/status/989828269183832064 https://twitter.com/Babybellno1/status/989836967985795072 In all actuality, the name Louis - which is also both one of Prince William and Prince George's middle names - is thought to be a nod to William's own dad, Prince Charles, whose great-uncle and mentor, Early Louis Mountbatten. The moniker also holds a particular level of significance for Prince Phillip, whose grandfather was Prince Louis Alexander of Battenberg.
