I don't think there's anything more precise.

EDIT: Ninja'd, but it hasn't disappeared, Taure.

 

It has disappeared in a way. In the older Pottermore there was an entry on schools in general, which mentioned Beauxbatons, Durmstrang and the Japanese school all in the same text. In the new Pottermore there are separate articles on Beauxbatons and Durmstrang (most of it verbatim from the old Pottermore).

 

What happened to the witches and wizards who the Ministry interrogated (Muggleborns and Half bloods)?

 

Considering the bullshit that happens in real life and seeing as the ministry was always pretty corrupt I'd say post war England probably had them struggling to start from scratch minus the overt prejudice under Voldemort's rule.

 

I meant immediately after the interrogations? Were they executed or used in camps..? I presume the latter since there's parallels between Hitler and Voldemort and I'm sure Rowling said herself she based the DEs and their views on Hitler

 

Oh. It's mentioned in the chapter "Muggleborn Registration Commission" of DH that those who resisted got the dementor's kiss or Azkaban. Also just before the break in at Gringotts Hermione polyjuiced as Bellatrix is told by Travers that a muggleborn was reduced to that of a beggar looking for a wand to prove her status.

 

Is having a wand necessary to undergo Animagus transformation? In PoA, Pettigrew dives for Lupin’s wand and uses it to change into his rat form. However, Sirius escaped from Azkaban in his animagus form, without a wand I presume. Is there something that I’m missing out?

 

Pettigrew didn't have a wand when he transformed.

 

Did it ever actually say that Muggle Studies was taught by someone who had no idea about muggles? Or is that just Fanon?

 

Unless my memory serves me wrong it is fanon.

 

Well, in 1997 it was taught by Alecto Carrow, who claimed muggles were like animals, but that's a special case.
Charity Burbage, Carrow's predecessor, believed muggles and wizards were equal, at least according to Voldemort. When Hermoine Granger took the class she didn't seem to have any complaints. She taught third years why muggles use electricity, and presumably other things about muggles, so she must have known something.
Little is known about Burbage's predecessor, and his predecessor was Quirinus Quirrel.

 

Was anyone else, beyond the Weasleys, ever mentioned to be poor? Where there beggars ever mentioned too?

 

Apart from the wandless Muggle-borns in DH, none especially come to mind. The Gaunts were said to live in squalor, I think.

 

I believe it was said that the Creevy brothers were the sons of a milkman, which is not a highly paid profession.

 

Random question. Does Voldemort usually refer to Harry as "Harry" or as "Potter"? I know that Snape usually prefers the latter, but as for Voldemort I don't really have a clue.

Also on a much less random note. I have this really stupid idea for a fanfic that will probably never get written. It's set around WWI. The only problem is, I don't really know any canon characters from around then, and I'd hate to have OCs fill every role (there obviously will be OCs, but I'd like to keep them from dominating everything). Does anybody know of the major political players around that time, or just any other interesting characters? (Barring obvious characters who were alive during that time, such as Dumbledore) The HP wiki page lists Archer Evermonde as the Minister of Magic during WWI, and has some stuff about a Henry Potter, but that's really only two characters.

 

Do we have any hints on whether the Grangers were poor, rich, or middle-class?

 

They were both dentists, and she was an only child. Hermione also vacationed in France and went skiing over the winter holidays.

I'd say that makes them firmly upper-middle class at least. Like, definitely not poor.

 

That was up until Hermione obliviated them and sent them live in a cardboard box out in the middle of the Outback.

It's mentioned in Rowling's 8th book "Harry Potter and Shitty Witness Protection Program"

 

They would go on holiday abroad fairly frequently. Her parents are dentists, which is a well-paid position. But they do both work. They're middle class.
