Much like the article I posted regarding facts that were changed or edited from the Harry Potter books, there are also tons of trivia bits that J.K. Rowling has released throughout the years about the Harry Potter universe that would have otherwise gone unknown.

While there are, I'm sure, many more than the eleven I included, they are spread pretty far and wide across the Internet. These are just some of my favorites.

1. Fred and George were born on April Fools’ Day

Of course the co-creators of Weasleys' Wizard Wheezes were born on April first! Does this even need explanation?

2. Despite what Ron said in Order of the Phoenix, Prefects can deduct points from students

If only Ron had known this when he was a prefect! Maybe he would have been seen as more of an authority figure.

3. Dean Thomas’ father was murdered by Death Eaters

Both Dean and his mother never found out. Sad.

4. Dragons cannot be domesticated

Sorry, Hagrid, but Norbert(a) could have never really been yours. Or maybe he (later disclosed to be a "she" after being in Charlie Weasley's care) could have, but it definitely would not have have been safe or appropriate for school grounds.

5. There were about 1,000 students at Hogwarts

While the numbers seem a bit fishy here, it is hard to argue with J.K. Rowling herself who gave this figure to in an interview back in 2000.

6. You have to be able to comprehend death in order for the Thestrals to be visible to you

This is why Harry couldn't see Thestrals until after Cedric Diggory's death. When he saw Voldermort murder his mother, he wasn't able to emotionally understand her death.

7. The worth of a Galleon is about $7.30, £5 Pounds, or €8

Naturally the exchange rate varies from year to year, but that’s a pretty close estimate.

8. Any Muggle money that Gringotts receives gets put back into circulation

I guess it makes sense that Muggle-borns would need to exchange their cash for Wizard money when venturing onto Diagon Alley. I’m not entirely sure how exactly they do this, but they’re goblins! I’m sure they have their ways.

9. Some of the Hogwarts professors are married

This is something that I just assumed, but I do find it a bit confusing. Do they live together in the castle? Do their spouses have other jobs? If apparating and the Floo networks are out of the question, how would they commute to work? Maybe this contributed to Sybil Trelawney's failed marriage. I have a hard time believing it was only the name Higglebottom that set her off.

10. Trelawney was a Ravenclaw and Hagrid was a Gryffindor

Rowling made the statement last year that Trelawney was in the Ravenclaw House, but it's been known for a while now that Hagrid was, like Harry, Ron, and Hermione, a Gryffindor.

11. Hagrid never marries

In Rowling's words to the joint Barnes and Noble & Yahoo! live chat:

Does Hagrid get a wife? You think anyone would want to live with a man who breeds Blast-Ended Skrewts?

She makes a decent point.

This isn't really something related to the books, but I thought this was fun. In the same live chat (which took place before Order of the Phoenix was released) monicapilman asked:

The character of Professor Snape fascinates me. Will you reveal his backstory further in the next Harry Potter book?

To which Rowling replied:

You will find out more about Snape in future books. Keep an eye on him!

And boy, she did not disappoint!

I just love remembering reading these books as they were coming out. Being able to live and grow with these stories was such a treat.

I'm also glad that J.K. Rowling has been so willing to share more about Harry Potter's world throughout the years. From new short stories, to answering questions on Twitter, she's always been highly devoted to her loyal fanbase!
