Yes, Severus Snape was a member of Slytherin House at Hogwarts School of Witchcraft and Wizardry.
But when they went to Hogwarts, everything changed. The pair were parted when the Sorting Hat placed Severus in Slytherin and Lily in Gryffindor, and while Lily thrived in her new, magical life, Snape was essentially placed in close quarters with the likes of Lucius Malfoy, Avery and Mulciber.
Family information
Salazar was the father of Severus Snape, the father-in-law of Snowdrop Evans and Tom Riddle, and the second maternal grandfather of Violet and Solana Peverell-Prince-Gaunt. Salazar was abusive, mentally, physically, and emotionally, towards his son while Norabelle was neglectful, cold, and callous.
Namely, that Voldemort, Snape and Harry are the three brothers. Voldemort is the eldest brother, Antioch Peverell, who asked for the most powerful wand in existence, and swiftly snuffed it.
Severus was Sorted into Ravenclaw, thankfully avoiding being sorted into Slytherin, as that would put a strain on his relationship with his best friend and true love, Lily Evans. While attending Hogwarts, it was noticed since his first day that the boy was a prodigy.
Lily Luna Potter (September 1, 2008-Present) is a Half-blood Witch born to Harry and Ginny Potter (née Weasley). From 2019 to 2026 she attended Hogwarts School of Witchcraft and Wizardry, where she was sorted into Ravenclaw. Lily has two older brothers, James Sirius Potter and Albus Potter.
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.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts.
Mason Riddle is the Son of Tom Marvalo Riddle, otherwise known as Lord Voldemort, and the only American student at Hogwarts School of Witchcraft and Wizardry. He is one of the only students who switched houses from Slytherin, to Gryffindor.
Snape was revealed to have been in love with Harry Potter's mother, Lily, since childhood. That feeling lasted beyond her death, and into his own final moments. That's why it's so surprising that Snape became a Death Eater.
In the Chamber itself, we see a large statue of a wizard, which Harry presumes is Salazar Slytherin. We also meet Tom Riddle, who is, as it turns out, the heir of Slytherin. Present only in spirit, he has all the same been controlling Ginny, and having her act as Slytherin's heir.
Her real parents were Daneel and Dean Novak, Pureblooded wizards. Turns out Daneel was Tom Riddles younger sister, Daneel Riddle. Of course, the Riddles were related to Salzar Slytherin himself, and this made Hermione the living heir of Slytherin. The problem with being a female Slytherin heir, is that they're cursed.
History of Slytherin
The Head of Slytherin is Horace Slughorn (who left the role to Severus Snape for fifteen years before taking it up again in 1996) and the House's patron ghost is the Bloody Baron.
He is cunning
Slytherins are a cunning lot, and there are all kinds of examples of Albus Potter using his wiles to come up with schemes and plans worthy of any member of Salazar's house throughout Harry Potter and the Cursed Child.
Harry Potter came very close to being sorted into Slytherin before he persuaded the Hat to sort him into Gryffindor. Yet the spectre of Slytherin haunted him for some time afterwards, becoming particularly potent in Harry Potter and the Chamber of Secrets, when he was rumoured to be the heir of Slytherin.
He doesn't trust Snape as Dumbledore does, but he believes that he can detect any disloyalty. Moreover, Voldemort regards Snape as highly intelligent and therefore ' as a true Slytherin ' a person whose top priority is to take care of himself.
Delphini, nicknamed Delphi, is the titular main antagonist of Harry Potter and the Cursed Child. Although she initially introduces herself as the niece of Amos Diggory, Delphi is in fact, the child of Lord Voldemort and Bellatrix Lestrange and has only one goal, restoring her father.
The reason why is shockingly mundane: His cousin bet that he couldn't get into the House if his life depended on it. So Albus proved him wrong, likely by just telling the Sorting Hat to put him in Gryffindor.
Delphini's birth was one of the most well-guarded secrets of Voldemort and his servants. She was sent to live with Euphemia Rowle, who only raised her because she was offered gold, though we don't know who paid her.
Dumbledore reveals how thoroughly he loves Harry. Harry is brave, and Dumbledore is proud as any father would be. More than that, Dumbledore succumbs to a parent's weakness; he cares more about Harry's happiness and wellbeing than the wizarding world he is trying to protect.
As Rowling explained in a series of tweets, Snape loved Harry's mother, Lily, and his unrequited affection drove him to resent Harry's father, James — and by extension, Harry himself.
They were close friends, she saw in him someone special that she could care about. But she couldn't be with him. So, it seems like it was very unlikely that Lily ever found out Snape loved her.
And yet that's a fact that we all often seem to overlook. Draco's mother is Narcissa Black, which makes Draco Sirius' second cousin.
He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse. It was a testament to Hermione's toughness that she was able to walk away without lasting damage.
