So how are Sirius and the Weasleys related? Phineas Nigellus Black is Sirius' great-great-grandfather and Arthur's great-grandfather, making the two men second cousins once removed. (Sirius correctly notes the relationship in Order of the Phoenix.)
The Malfoys are related to the Black family through Narcissa (a first cousin of Sirius Black, Harry's godfather), which makes Draco a nephew of both Bellatrix Lestrange and Andromeda Tonks. Draco is also Nymphadora Tonks' first cousin through their mothers.
They're Related To The Weasleys (And Potters)
That's because they hail from pure-blood families, which only marry into other pure-blood families.
Ron's grandfather, Septimus Weasley, was married to Cedrella Black. Cedrella's uncle, Sirius Black II, had a grandson, Orion Black through his son Arcturus Black III. Orion Black is the father of Sirius Black. So basically, Sirius Black's great aunt is Ron Weasley's grandmother.
Ron is related to Draco Malfoy; Ron's grandmother was a Black, who are related to the Malfoys through Narcissa.
Hermione Malfoy (née Granger) is the daughter of Mr Granger and Mrs Granger, wife of Draco Malfoy, Daughter-in-law of Lucius Malfoy and Narcissa Malfoy (née Black), Mother of Hyperion, Hyperion II, Scorpius, sister-in-law of Miss Malfoy and friend of Harry Potter.
No, Harry Potter and Draco Malfoy were not related. Sirius Black, Harry's godfather, was not related to Draco Malfoy. As pointed out, Sirius Black was actually Draco's first cousin once removed - not his uncle.
Sirius Black and James Potter attended Hogwarts together, and Sirius is Harry's godfather. Sirius is an Animagus, which means he can transform himself into a black, shaggy dog named Padfoot at will.
For example, did you know that Sirius is actually related to Neville Longbottom? Yes! It may be hard to believe, but that is exactly the case. Though we imagine the Blacks were not pleased with Neville's parents and their joining of the Order of the Phoenix.
Sirius' family tree includes some nefarious characters. Bellatrix Lestrange, Narcissa Malfoy, and Sirius Black are all descendants of Pollux Black, making them first cousins.
Neither of them is Slytherin's heir. Although, as Dumbledore says, Harry's ability to speak Parseltongue is a skill accidentally transferred by Slytherin's actual heir, Voldemort, when he tried to kill Harry as a baby. So perhaps this is one myth with a bit of truth to it.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Bellatrix is the eldest Black sister and is extremely similar to the first brother in that she is obsessed with power. From a young age, she had a fascination with the Dark Arts. As she grew, this fascination turned to obsession, and she becomes one of the most infamous Death Eaters.
In some cases (the Malfoy family) blood traitors are a bad as Mudbloods. As other people said, it is also due to the Malfoys' arrogance, the feeling of self-importance and wealth. The Weasly family is also very poor, which may also lead to a dislike with the rich, pureblood families.
Andromeda married a Muggle-born, Ted Tonks, and was subsequently disowned by the Blacks, whereas Narcissa, conversely, married Lucius Malfoy, heir of a wealthy pure-blood family; thus, Bellatrix is the aunt of both Nymphadora Tonks and Draco Malfoy, respectively.
Sirius's early life proved unhappy; he had come to hate most of his relatives, in particular his mother. He rejected his family's pure-blood elitism and reverence for the Dark Arts. At Hogwarts, rather than be sorted into Slytherin like the rest of his family, Sirius was placed in Gryffindor.
In the end, both were essential to Voldemort's downfall, fulfilling the possibility that both Harry and Neville were, in fact, the Chosen One. While Harry delivered the final blow to destroy Voldemort, Neville destroyed the final Horcrux which allowed Harry to end Voldemort.
The answer is that Sirius wanted to deflect attention from the real Secret-Keeper. He probably hoped Voldemort would go after him so he could steer attention away from Pettigrew.
Sirius Black had to die, because otherwise Harry could have been happy. And a happy Harry does not an epic story make. Yes, obviously, Harry had some good moments, but let's face it, most of his life, particularly as it got closer to the end of the series, was miserable.
Get away from my godson! Sirius Black (born November 3, 1959 - died June 18, 1996, aged 36), also known by his nickname Padfoot, is a major character from the Harry Potter series.
Having rendered unknown, shady, (and almost certainly magical) services to King William I, Malfoy was given a prime piece of land in Wiltshire, seized from local landowners, upon which his descendants have lived for ten consecutive centuries.
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.
Malfoy married pureblood Astoria Greengrass, who did not raise their son to believe Muggles or others were less than purebloods.
