Ever since Harry Potter and the Deathly Hallows was released, JK Rowling has unveiled several new tidbits about the wizarding world via her Twitter account as well as the website, Pottermore. Here are some of the more notable ones that I could find:
The Reason Harry Potter is Rich
One of the first things Harry does when he finds out he's a wizard is to visit Diagon Alley to purchase school stuff. But first, he goes to Gringotts Bank, where to his surprise, he discovers that he is rich, but the reader is never given any explanation as to why.
In reality, Harry can thank his ancestor, Linfred of Stinchcombe for his wealth. Stinchcombe developed several pharmaceutical remedies that readers would eventually come to know as Skele-gro and Pepper up Potion. in the 12th century.
Harry's grandfather Fleamont Potter ended up quadrupling the family fortune with the development of his hair potion several centuries later, leading to the mounds of gold in Harry’s vault.
Dumbledore’s Name has Many Meanings
Dumbledore’s full name, Albus Percival Wulfric Brian Dumbledore might be long, but each name carries a specific meaning.
"Albus" is Latin for "white," which could be symbolic of his relationship to Harry or his status as the antithesis of Voldemort.
"Percival" was one of King Arthur's Knights of the Round Table, who went in search for the lost grail; a reference to the Deathly Hallows.
"Wulfric" is said to be a reference to the 12th-century British figure Wulfric of Haselbury, known as a miracle worker.
"Brian" is said to be derived from an Old Celtic word that means "noble."
"Dumbledore" is an Old English word for "bumblebee", and in-joke by Rowling who stated:
Since Albus Dumbledore is very fond of music, I always imagined him as sort of humming to himself a lot
A Lot of Animals Worked on the Harry Potter Films
Harry's owl, Hedwig, was played by four different owls. More than a dozen-plus rat played Ron’s rat, Scabbers. Four different cats played Hermione's pet, Crookshanks. Nine Neapolitan Mastiffs played Hagrid's dog, Fang.
There’s Another Harry Potter in Harry’s Family Tree
Harry Potter shares his name with his great grandfather, who lived in the late 1800s and early 1900s. His real name was Henry Potter, but his colleagues and friends called him Harry. He served on the Wizengamot from 1913 - 1921.
Henry stirred up some controversy when he publicly criticized the Minister of Magic, Archer Evermonde, who had forbidden the magical community to help Muggles struggling due to World War I. This led to the family’s expulsion from the Sacred Twenty-Eight, a list of pureblood wizarding families.
He lived around the time of the movie series, Fantastic Beasts and Where to Find Them, so don’t be surprised if he eventually makes an appearance. I nominate Daniel Radcliffe to play him.
The Reason Why the Horcrux Inside Harry Wasn't Destroyed Earlier
Several fans used to point out a plothole in Chamber of Secrets involving the Horcrux residing in Harry.
Harry was bitten by a basilisk in the book. Since basilisk fangs can destroy Horcruxes, it was surmised that the one inside Harry should have also been destroyed. However, Rowling throws cold water on this theory, stating:
A Horcrux can only be destroyed if its container is damaged beyond repair. Harry was healed by Fawkes. Had he died, the Horcrux would indeed have been destroyed.
There’s a Secret Character Hidden in the Movies
Nearly every Harry Potter film features a newspaper headline of some sort. The people who designed them had a lot of fun with them and included an easter egg. Each paper features stories about The Ginger Witch, who is apparently a real hooligan, possessing a criminal career spanning the decades, which includes stealing wigs and breaking out of Azkaban prison.
