Harry Potter needs no introduction. Ever since he came into the world in 1997 via Harry Potter and the Philosopher's Stone, he's been a staple of any fantasy lover's library, young or old. Despite the seventh and final book having been published nearly a decade ago in 2007, his influence is as strong as ever due to the film series (which ended in 2011), endless merchandising and a steady trickle of new projects that occupy the Harry Potter world.
Perhaps acknowledging that the world's most famous boy wizard is too much of a cash cow for Hollywood to just leave alone, author J.K. Rowling has at least committed to being involved with these new projects, like stepping in to write the screenplay for Fantastic Beasts and Where to Find Them. If they have to be made, they should be with the input of the mind where it all began.
Rowling does still like to give diehard fans a little treat with occasional tidbits or entire new short stories about iconic characters from her original books, such as the revelation soon after publishing her final book that Dumbledore is gay. Rarely has she illuminated more about Harry himself, though, until now.
"The Potter Family"
Rowling's Pottermore, a site dedicated to giving fans, well, more of Potter, just underwent a major revamp. Somewhat lost in the hubbub of that revamp was a brand-new short story that illuminates a great deal about the history of Harry's family and where they came from, naming many of his ancestors we never new.
Most excitingly, though, it also confirms the theory about where his invisibility cloak came from.
In the Tale of the Three Brothers, which comes about in Deathly Hallows, the youngest brother of three receives an invisibility cloak from Death and is able to evade him for the rest of his life until he dies of natural causes. It's discovered that this tale is in fact real (in the universe of Harry Potter), and that the brothers' surname was Peverell. Because Harry's own invisibility cloak is a crucial part of the entire series, it's not difficult to draw the connection that Harry's is likely the same one referred to in the tale, which means he must be distantly related to the Peverells.
But how? That's what the new story tells.
"The wizarding family of Potters descends from the twelfth century wizard Linfred of Stinchcombe, a locally well-beloved and eccentric man, whose nickname, 'the Potterer,' became corrupted in time to 'Potter,'" Rowling's new story reads, and later continues, "Linfred's eldest son, Hardwin, married a beautiful young witch by the name of Iolanthe Peverell, who came from the village of Godric's Hollow. She was the granddaughter of Ignotus Peverell."
Ignotus is the youngest brother in the aforementioned tale and the original owner of the cloak. So there you have it.
