**I’m trying to put one together below.** (Work in progress)

I wrote a Python script to access Twitter’s API, and get a complete list of JK Rowling’s tweets. Then I threw away anything that was a retweet or contained an obviously non-Potter related phrase (e.g. “BBC” or “Lumos”).
That left about 2500 tweets, which I went through by hand looking for new canon information. Finally I wrote the list below.

Per Accio Quote rules, only information in quotation marks is from JKR herself – everything else is my paraphrasing. Links throughout.

### Characters

</p>

*   Although he was gay, Dumbledore didn’t experience homophobia in the magical world. [“The wizards don't give a damn – it's all about the magic for them.”](https://twitter.com/jk_rowling/status/508706921566969856).
    Hogwarts was a [safe space for LGBT students](https://twitter.com/jk_rowling/status/544998416414412801).

*   Anthony Goldstein (a Ravenclaw student in Harry’s year) was [Jewish](https://twitter.com/jk_rowling/status/544946669448867841). He wasn’t the [first or only Jewish student](http://twitter.com/jk_rowling/status/545149848170016768) in the school, but he got special mention because he was [one of the original forty students](http://twitter.com/jk_rowling/status/545151163596038144).

*   On the topic of religion, the only religion she [didn’t imagine](http://twitter.com/jk_rowling/status/544995944404897792) at Hogwarts was [Wiccan](http://twitter.com/jk_rowling/status/544996025073541121).

*   Fluffy was [“repatriated to Greece”](https://twitter.com/jk_rowling/status/563634348524843008) by Dumbledore.

*   Ron's Patronus [is a Jack Russell](https://twitter.com/jk_rowling/status/594072117336997888).

*   Moaning Myrtle's full name is [Myrtle Elizabeth Warren](http://twitter.com/jk_rowling/status/597730858808782848).

*   Of the two Weasley twins, [Fred was born first](http://twitter.com/jk_rowling/status/602105708511961091).

*   Harry [intentionally didn’t name a child ‘Remus’](http://twitter.com/jk_rowling/status/606878809829310464), so that Teddy could use the name for his own son.

*   Madam Pince comes from a [childhood fear of scary librarians](https://twitter.com/jk_rowling/status/614141084034318336). (I’m slightly guessing – the context from the tweet she was replying to is missing.)

*   Luna’s birthday is [13th February](http://twitter.com/jk_rowling/status/622008983000363008).

*   Uncle Vernon [loves Top Gear](https://twitter.com/jk_rowling/status/622155949848023040) and [signed the petition for Clarkson’s reinstatement](https://twitter.com/jk_rowling/status/622157481582698496). But when asked if Vernon would make a good host, she said [“His total lack of charm or charisma might have prevented it becoming a global franchise”](http://twitter.com/jk_rowling/status/622156729929867265).

* Hagrid [couldn’t produce a Patronus](http://twitter.com/jk_rowling/status/634666242943655936).

* James S Potter (Harry’s son) was sorted into Gryffindor. Teddy Lupin was sorted into Hufflepuff, and eventually became Head Boy. ([tweet](http://twitter.com/jk_rowling/status/638778021663666176))

* Ron is [not a time-travelling Dumbledore](http://twitter.com/jk_rowling/status/649913211521794048). Nor is [Draco a werewolf](https://twitter.com/jk_rowling/status/649915813831512064), or Snape a vampire.

* Sirius’s birthday is [3rd November](http://twitter.com/jk_rowling/status/652868162703237120).

### Places

*   Grimmauld Place was [acquired by a Black ancestor](https://twitter.com/jk_rowling/status/563635069102080000), who liked the house and “persuaded” the resident Muggles to leave.

*   The Salem Witches’ Institute (first mentioned in *Goblet of Fire*) was long believed to be the American school of magic – in fact, it’s just a joke about [the Womens’ Institute](http://twitter.com/jk_rowling/status/607275327111458816).

    The name of the American school (now known to be Ilvermorny) is of [“immigrant origin”](http://twitter.com/jk_rowling/status/607457246637912064). [“Indigenous magic was important in the founding of the school”](http://twitter.com/jk_rowling/status/607458078427082752), but she declined to say which tribes, to avoid giving away the location.

* Flourish and Blotts, the Diagon Alley bookstore, is [“about halfway down Diagon Alley on the left hand side”](http://twitter.com/jk_rowling/status/630391064881459200)

### Magic

</p>

*   Why wasn’t the soul fragment in Harry destroyed in *Chamber of Secrets*? Because it has to be [“destroyed BEYOND REPAIR, so Harry would need to have DIED”](http://twitter.com/jk_rowling/status/563633021837131777).

    With the ring, the [cracked stone was irreparable](https://twitter.com/jk_rowling/status/563737784754896896), but the magic of the resurrection stone survived. Only Dumbledore could have destroyed the horcrux but not the original charm.

*   What cause a Patronus to change? [“If it's eternal love, unchanging - part of you forever.”](http://twitter.com/jk_rowling/status/601377849744990208)

### *Fantastic Beasts and Where to Find Them*

</p>

This is the [new film](https://en.wikipedia.org/wiki/Fantastic_Beasts_and_Where_to_Find_Them_(film)) based on the [book of the same name](https://en.wikipedia.org/wiki/Fantastic_Beasts_and_Where_to_Find_Them), due for release in November 2016.
Rowling has been dropping information about the film on Twitter.

*   Newt Scamander is [a Hufflepuff](http://twitter.com/jk_rowling/status/519590661004079104).

*   The first line is [“Newt Scamander only meant to stay in New York for a few hours”](https://twitter.com/jk_rowling/status/519590976243769345).  Initially posted as [an anagram](http://twitter.com/jk_rowling/status/519051167767478272) for her followers to unscramble.

*   Newt will [meet characters from the American school of magic](http://twitter.com/jk_rowling/status/607277795543273472).  It sounds like the American school [also has a house system](http://twitter.com/jk_rowling/status/622162435160571904), and she knows where those characters fit. (It could mean she knows their Hogwarts houses, even though they were never sorted.)

*   There’s a character with [“loads of scars”](http://twitter.com/jk_rowling/status/621729177482473472).

*   There are two characters – Portentina (shortened to to Tina) and Queenie – who have [the surname Goldstein](http://twitter.com/jk_rowling/status/632611203924238336) and are distantly related to [Anthony Goldstein](http://twitter.com/jk_rowling/status/632611629843263488) in Harry’s year.


### *Harry Potter and the Cursed Child*

</p>

This is a play happening in London, [announced on Twitter](http://twitter.com/jk_rowling/status/614335053724811264).

*   [It's not a prequel.](http://twitter.com/jk_rowling/status/614336035712073728) (She says this a lot.)

*   She [considers it canon](http://twitter.com/jk_rowling/status/615498601809211393), although the script was written by [Jack Thorne, not her](http://twitter.com/jk_rowling/status/615498234107154432).

* It would [“give away a huge amount”](http://twitter.com/jk_rowling/status/634665468117274624) to tell us who the cursed child is.

### Other

</p>

*   The gems in the Hufflepuff hourglass [are diamonds](http://twitter.com/jk_rowling/status/459683482575572992).

*   The Bulgarians are [“outstanding at Quidditch”](https://twitter.com/jk_rowling/status/611614276286054403).

*   The Ministry of Magic covers [the costs of magical education](http://twitter.com/jk_rowling/status/622118373061709824), at least for Hogwarts students.

*   The Magical Congress of the USA is [a single body](https://twitter.com/jk_rowling/status/630123670585909249), unlike the two-part real-world Congress.

*   The equivalent of the United Nations is [the International Confederation of Wizards](http://twitter.com/jk_rowling/status/630125966606630912).

* If Crookshanks and Mrs. Norris were to have a fight, Crookshanks’s Kneazle ancestry [would give him the edge](https://twitter.com/jk_rowling/status/644197707939213312).
