Harry himself is a half-blood, since his pure-blood father, James, married a Muggle-born witch named Lily, and his maternal grandparents were Muggles.
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.
Even though Harry's father (James) was a pure-blood, Harry himself is a half-blood because his magical mother, Lily Evans, was a Muggle-born. Basically, a half-blood is any magical person who has a mixture of magical and non-magical ancestry.
The children of Harry and Ginny Potter were considered half-bloods because although Ginny was pure-blood, Harry's mother was Muggle-born. The term was used as an insult from members of fanatical pure-blood families.
The name was accurate, as he was indeed from half-blood lineage. Snape's mother was a witch named Eileen Prince, while his father was Tobias Snape, a muggle. In terms of story-writing purposes, it draws a parallel to Harry, who was also a half-blood because his mother, Lily, was muggle-born.
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. As the series progresses, Snape's character becomes more layered and enigmatic.
His father was neglectful and sometimes abusive, which may have contributed to Snape's disdain for Muggles. At some point during his school years, he decided to reject his father's name entirely, giving himself the moniker "The Half-Blood Prince" with his mother's maiden name instead.
Neville is a pure-blood wizard born to Frank and Alice Longbottom, who were prominent Aurors and also members of the Order of the Phoenix during the first war against Lord Voldemort.
Though nominally a Muggle-born witch, Hermione is descended from the Dagworth-Granger family through her father's squib heritage. Though not an Ancient and Noble or Noble House, the Dagworth-Granger family is known for their natural potion-making skills.
It is perhaps interesting that Voldemort himself is not a pureblood; while his mother, Merope Gaunt, was a member of one of the oldest Wizarding familes in existence, his hated father was a “Mudblood”. In spite of this, he is still considered the heir of Salazar Slytherin.
Bellatrix used a powerful "love potion" on Voldemort and they have sex while he is temporarily obsessed with her. She then uses obliviate on him while he sleeps (you know, he falls asleep after his post-sex cigarette) and tells everyone that the baby is her and her husband's.
Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her. We know that he did not date anyone, even when at Hogwarts.
Voldemort is motivated by immortality, superiority, racial cleansing, and more than a bit of self-hatred. Many of these things are shown in earlier books in the series, but become crystallized in the sixth. Tom Riddle has a witch mother and a Muggle father, making him a half-blood wizard.
Draco Lucius Malfoy (b. 5 June, 1980) was a pure-blood wizard and the only son of Lucius and Narcissa Malfoy. The son of a Death Eater, Draco was raised to believe strongly in the importance of blood purity. He attended Hogwarts School of Witchcraft and Wizardry from 1991-1998 and was sorted into Slytherin House.
Blood purity
Muggle-born Slytherins existed, but were very rare, as noted insultingly by Scabior the Snatcher. There had also been definite examples of half-bloods sorted into the house, including Tom Riddle, Dolores Umbridge, and Severus Snape.
There aren't that many pureblood families left, and one of which is basically exclusively Gryffindor, anyway. So no, Slytherins are definitely not always purebloods, and I don't think it's ever been, either.
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.
Harry is the Heir of Gryffindor (though his powers have been bound by his father when he was a baby), Neville is the Heir of Hufflepuff, Meghan (OFC, daughter of Sirius) is the Heir of Ravenclaw.
Ginny is a pureblood witch born 11 August 1981, the seventh child and only daughter of Arthur and Molly Weasley. She attends Hogwarts School of Witchcraft and Wizardry, and is sorted into Gryffindor house, along with the rest of her family.
And so, the Blacks blasted Cedrella (like Sirius) from the tree for her treachery. The Weasleys descend from Cedrella Black, a granddaughter of Phineas Nigellus Black. Sirius Black, Bellatrix Lestrange and Narcissa Malfoy all descend from Pollux Black (left).
Over the years, fans have criticized the titular Harry Potter character for allowing The Weasley family to live in poverty even though he had enough wealth to help them. The Weasleys were known in the wizarding world for being of lower economic status, something the Malfoys loved to remind them of.
McGonagall was born a half-blood witch as her father was a Muggle and her mother a witch. McGonagall began her Hogwarts education at the age of eleven and was sorted into Gryffindor after being the longest ever Hatstall between Gryffindor and Ravenclaw.
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. To his twisted mind, selfless equals stupid.
For the Potter uninitiated, “always” is how Snape explains to Dumbledore in the final book why his Patronus takes the same shape as the one belonging to his long-lost love: Harry Potter's mother, Lily.
