Her sister Narcissa (another of Sirius' first cousins) married Lucius Malfoy, himself a renowned Dark wizard instrumental to Voldemort's rise. Harry also fought against their son (Sirius' first cousin once removed), Draco, a wannabe Death Eater tasked with killing Albus Dumbledore.
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.
Lucius Malfoy (b. c. 1954) was a British pure-blood wizard, the son of Abraxas Malfoy, husband of Narcissa Black, father of Draco Malfoy and paternal grandfather of Scorpius Malfoy. As well as a member of the Malfoy family. Lucius was educated at Hogwarts, where he was made a prefect in Slytherin House.
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.
His parents, Orion and Walburga Black, were both Blacks by birth and second cousins. Sirius had a younger brother, Regulus Arcturus Black, and three older cousins: Bellatrix Lestrange, Andromeda Tonks (his favourite cousin and mother of Nymphadora Tonks), and Narcissa Malfoy (mother of Draco Malfoy).
How EVERY Harry Potter Character is RELATED (All Family Trees Explained)
Who did Sirius Black have a child with?
Black did not have a wife or children. As the portrait of Phineas Nigellus, Black's deceased great-great-grandfather, stated, the direct line of the ancient Black family ended with Sirius' death. Had Regulus Black lived, he would have been the heir of the Black home; however, he predeceased Sirius.
As the daughter of Sirius Black, Cassiopeia is the rightful blood heir to the House, despite being female. As a pureblood, Cassiopeia is related to many wizarding families, such as the Malfoys, Tonks, Weasleys, Prewetts, Longbottoms, Crabbes, Flints, Crouchs, and others.
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.
Her sister Narcissa (another of Sirius' first cousins) married Lucius Malfoy, himself a renowned Dark wizard instrumental to Voldemort's rise. Harry also fought against their son (Sirius' first cousin once removed), Draco, a wannabe Death Eater tasked with killing Albus Dumbledore.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
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.
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.
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.
Hermione was a prominent example of this as, on the surface, she appeared like someone who would fit right into Ravenclaw. But beyond her interests, her values define her as someone with a take-charge personality and bravery to spare. Unlike Ravenclaws, she didn't apply knowledge in unique ways.
They may be related, but that would have to be very distantly. Luna's father is Xenophilius Lovegood, and her mother died in front of her when she was nine. Draco's father is Lucius Malfoy, and his mother is Narcissa Malfoy, née Black. So even if they're related, they most definitely are not siblings.
An interesting fact of note is that despite the ideals that pure-bloods are inherently more powerful wizards, some of the most powerful or particularly adept wizards and witches in the series are in fact either half-blood (such as Lord Voldemort, Albus Dumbledore, Minerva McGonagall, Severus Snape and Harry Potter) or ...
In the play "Harry Potter and the Cursed Child," which has become part of "Harry Potter" canon, it was revealed that Bellatrix conceived a child with none other than Lord Voldemort.
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.
Lord Voldemort had no wife he and Bellatrix just made a baby together. Voldemort couldn't love anyone. But the girl mother (In cursed child) is Bellatrix Leatrange.
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.
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. So once again we find this family tree getting just a bit more complex and twisted.
Remus fought at the Battle of Hogwarts on 2 May 1998, during which his wife was murdered by Bellatrix Lestrange. Remus was also murdered by Death Eater Antonin Dolohov, during the first half of the same battle. His death was possibly avenged by Filius Flitwick.
