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.) Given that, Sirius can call the seven Weasley children his third cousins.
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.
He marries Narcissa Black and together they have one son, Draco, who is the first Malfoy family member introduced in the series. 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.
The Potters were related to the Peverell, Fleamont, Black, Evans and Weasley families, and more distantly to the Gaunt, Riddle, Flint, Bulstrode, Riddle family, Crabbe, Dursley, Prewett, Delacour, Johnson, Granger and Granger-Weasley families.
Literally (by blood), he was the Black Heir. His mother, Walpurga Black, father Orion Black, brother, Regulus Black, and cousins; Andromeda, Narcissa, and Bellatrix Black. Though he was disowned and I doubt he considered them family at all by the time he was leaving Hogwarts.
The REAL Reason the Weasleys Are So POOR (They're CURSED) - Harry Potter Theory
How did Voldemort and Bellatrix have a child?
Delphini was born in secret at Malfoy Manor in early March 1998 as the result of a liaison between Bellatrix Lestrange and Lord Voldemort. On 2 May 1998, both of her biological parents were killed in the Battle of Hogwarts.
Cedrella and Septimus went on to have three children together, one of whom was Arthur Weasley – Ron's father. This means that Draco and Ron are distantly related, making Draco's bigoted pure-blooded ideology even more ironic.
In Order of the Phoenix, Bellatrix kills her first cousin Sirius, only to later be killed by Molly Weasley (Bellatrix's second cousin once removed by marriage). In addition, Lucius Malfoy and Arthur Weasley have a well-established feud despite being second cousins once removed by marriage.
The Peverells, Gaunts, Blacks, Malfoys, Potters, Weasleys, Prewetts, and other families are all linked to one another through bloodlines and intermarriage. The only known direct descendants from Salazar Slytherin were the Gaunts, who for the most part shared their ancestor's beliefs in the purity of wizard blood.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use. He has tons of happy memories... He had an amazing childhood. However, she also said Snape was the only Death Eater who could produce a Patronus.
In fact, Lucius' own support to Voldemort is revealed to come only under some form of duress, which is likely Narcissa's Veela Allure. When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her.
Bellatrix is related by blood and marriage to many characters in the novels (although in the fifth book it is specified that all pure-blood families are related to each other): she has two younger sisters, Narcissa and Andromeda, and is first cousin to Sirius.
Who is the richest Harry Potter actor? Radcliffe is currently the wealthiest actor from the Harry Potter franchise. The rest of the main kid cast's ranking, in order from highest to lowest estimated net worth, is: Emma Watson at $85 million.
The whole Weasley family – Molly, Arthur, and seven children – was Sorted into Gryffindor at Hogwarts, and they are united by their shared Gryffindor values of courage, loyalty, and leadership.
The pure-blood wizards and witches featured in the Harry Potter books are almost all supremacists, while there are some of them who do not advocate ancestral superiority; the Potters, Weasleys, and Longbottoms are old pure-blood families, but no known members of these families are sympathetic to supremacist aims.
She was raised by Euphemia Rowle then Rodolphus Lestrange. It would not be very surprising if they told her everything about Voldemort, his greatness, his power, his ambitions… since he was their master.
Under the influence of her father, Dolores grew up despising her mother and brother for their lack of magical abilities. She was sorted into Slytherin House at Hogwarts School of Witchcraft and Wizardry and hated her time at the school due to never being given any positions of power.
Harry Potter and the Cursed Child unearthed many revelations but none were as shocking as the introduction of Lord Voldemort's daughter, Delphini. The young Dark witch, nicknamed Delphi, was the product of Voldemort's romantic relationship with Bellatrix Lestrange.
Luna married fellow naturalist Rolf Scamander, grandson of Fantastic Beasts and Where to Find Them author Newt Scamander, considerably later in life than Harry, Ron, Hermione, and Ginny, who all married and started families in their early-to-mid twenties.
In the books, Pansy Parkinson has a schoolgirl crush on Draco, and they went together to the Yule Ball. However, there was no true love between them. In the Cursed Child, Draco Malfoy's wife is Astoria Greengrass. Later, after Astoria's death, Draco says that he would “sell [his] soul for another minute with Astoria.”
Harry Potter had a few love interests during his time at Hogwarts. Though he eventually settled down with Ginny Weasley, he also had a thing for Cho Chang in his earlier school years. Then, of course, there's his secret love for Draco Malfoy… Wait, what?
Malfoy is always at the receiving end of Ron's punches or hexes throughout the books. Ron fought and beat so many dangerous Death Eaters than Malfoy and survived. Malfoy sure knows more dark magic than Ron but he can not fight.
Yes, they are. Luna's mom, Pandora was the sister of Rebastian, and Rodolphus Lestange. Draco's aunt Bellatrix married Rodolphus so they are “cousins”.
Nymphadora Tonks and Draco Malfoy are cousins (1Cs). Neville Longbottom and Draco Malfoy are 4Cs. Harry Potter and Neville Longbottom are 3C1Rs. Ronald Weasley and Neville Longbottom are 2C1Rs.
