M. G. McGonagall was a Gryffindor student at Hogwarts School of Witchcraft and Wizardry in the early 1970s. They played on the Gryffindor Quidditch team, winning an award for it in 1971, which was displayed at Hogwarts on a plaque that also bore the names of James Potter and R. J. H. King.
McGonagall may have been related to Transfiguration teacher Minerva McGonagall.
* The name M. G. McGonagall appears only in the film adaptation of Harry Potter and the Philosopher's Stone. M. G. McGonagall cannot have been the same person as Minerva McGonagall, as Minerva attended Hogwarts as a student circa 1937 to 1944, and taught there beginning in December 1956.
*******
So M.G. McGonagall was on the same team when James was the seeker. Probably related to Minerva (a nephew, perhaps?) One reason she's such an ardent Gryffindor Quidditch supporter and buys Harry his first broom?
We won't know until Rowling publishes her encyclopedia.
What is it?
If you clicked on the link, you know what I know.
Tangentially related: Dun dun dun...
Ooooh, intriguing. (I hope it's not just the adventures of Albus Severus Hedwig Remus Nymphadora Fred Potter and pals. I'm not really interested in that. Not that I wouldn't read it.)
It's not a book. So it'll be something online, I guess.
Answering one of Consuela's old questions, JKR herself states: "Wizards can make themselves untraceable, which is why they can't be found simply by sending and following owls."
This might be why you can't conjure up food: "[Wizards need money because] there is legislation about what you can conjure and what you can't. Something that you conjure out of thin air will not last."
So you'd die of malnutrition if you ate magicked up food. Though "Accio Whopper" should work, no?
I'm not sure how effective the accio spell is in maintaining the integrity of whetver you've got flying at you but I'm guessing 'accio apple' might be a wee bit less messy.
BTW I'd like to know what principle of 'Defence Against the Dark Arts' Quirrell was demonstrating on that iguana. At least Barty Crouch used invertebrates.
Another tidbit, Fluffy (the three headed dog) is wandering the Forbidden Forest. Playing tag with the Ford Anglia, I hope.
Huh. Another question answered: "Avada kedavra "is an ancient spell in Aramaic, and it is the original of abracadabra, which means "let the thing be destroyed." Originally, it was used to cure illness and the "thing" was the illness, but I decided to make it the "thing" as in the person standing in front of me."
Another huh: Tonks was a Huffelpuff.
