Filch can't be in any house because he is a squib. But if he did magic, he'll probably go straight to Slytherin.
No, McGonagall wasn't Filch's mom. She never had a child. Filch belonged to a completely different wizarding family and was a squib.
Filch was Hogwarts' caretaker, but he was also a squib - a Muggle born from wizard parents (which may possibly be the case of Jacob Kowalski from Fantastic Beasts as well).
Early life. Little is known about Filch's early life. He was born to at least one wizard parent sometime before 1951, presumably somewhere in the British Isles. Despite his magical parentage, Filch was a Squib, meaning he could not perform magic.
Sorted into Gryffindor house, Remus Lupin was swiftly befriended by two cheerful, confident and rebellious boys, James Potter and Sirius Black. They were attracted by Remus's quiet sense of humour and a kindness that they valued, even if they did not always possess it themselves.
The fan asked the author if Aunt Petunia was a Squib (a non-magical person who is born to at least one magical parent) and Rowling replied: "Good question. No, she is not, she is not a Squib. She is a Muggle.
He can't cast a Patronus
In a Q&A with Harry Potter fans on Twitter, J.K. Rowling was quizzed what Hagrid's Patronus would be. In reply, she wrote, 'Hagrid couldn't produce a Patronus. It's a very difficult spell. '
Incidentally, can Squibs see Dementors? ' he added, looking left and right along the bench. 'Yes, we can!
Although like a Muggle they can't perform magic, a Squib is often far more integrated in the wizarding world. For while a Muggle is as Muggle can be, with Muggle family members and, well, Muggle everything, one of the main differences with a Squib is that they're related to a witch or wizard, just without the magic.
No, Argus Filch never attended Hogwarts. Squibs do not ever get the invitation letter. However, Filch seems to have always had a desire to be part of the wizarding world, and perhaps never wanted to integrate into Muggle society.
Mrs Norris was the pet cat of Argus Filch, the caretaker of Hogwarts School of Witchcraft and Wizardry. Mrs Norris was described as having an unusually strong connection with her master, alerting him to any students misbehaving inside the school castle. She was described as appearing almost the same way as Filch.
Mrs. Norris is the first victim of the Slytherin monster; she is found on Halloween night hanging by her tail from a torch bracket, stiff as a board. Filch thinks that Harry is the one who Petrified her because he knows that Filch is a Squib (a non-magical person with magic parents).
Conclusion: Mrs Norris not an animal.” After discounting the theory that she is an Animagus (a human, like Professor McGonagall, that can shift into an animal by choice), the YouTube video says she must be a Maledictus, who was a witch before being permanently turned into a cat.
There is an extremely famous Maine Coon called Maximus, however, you probably know the cat better as Mr Filch's trusty companion in Harry Potter, Mrs Norris.
A doe. And in his final battle with Lord Voldemort, Harry explained the significance of this to his adversary, and to us: 'Snape's Patronus was a doe,' said Harry, 'the same as my mother's, because he loved her for nearly all of his life, from the time when they were children'.
That's right – we wouldn't be surprised if some members of Slytherin house find themselves with a fox Patronus. Foxes are also highly adaptable and can live in many diverse habitats around the world. If deep down you're channelling the fox, you'll likely have resilience in spades.
Lily Potter (née Evans) was a Muggle-born witch and Harry's mother. She was born 30 January 1960 and died on 31 October 1981 at age 21. She was quite young, 19 years old, when she became pregnant with Harry, giving birth to him at 20.
James's Animagus form was that of a stag, which earned him his nickname, Prongs. Strikingly, Harry's Patronus was a stag and his mother Lily's was a doe, a female deer, showing that the family's characters were in harmony and formed part of the same animal group.
Harry James Potter holds half-blood status in Rowling's imagined wizarding world because his mother is Muggle-born and his father is pure-blood. There are three main blood statuses; pure-blood, half-blood, and Muggle-born, which are all methods of determining a witch or wizard's magical lineage.
At Hogwarts, she, along with her sisters, was sorted into Slytherin. It is suggested in the novels that, as a student, Bellatrix associated with a group of students – including Rodolphus Lestrange, Severus Snape, Avery, Evan Rosier and Wilkes – who nearly all became Death Eaters.
Tom was educated at Hogwarts School of Witchcraft and Wizardry from 1938 to 1945, and was Sorted into Slytherin House, a nod to his ancestor Salazar Slytherin himself.
Sirius bucked the trend in the Black family by being sorted into Gryffindor as opposed to Slytherin, like the rest of his family.
