Indeed, his mother blasted him (and other “traitors”) off the family tree that hung in the ancestral Black home. Sirius' family tree includes some nefarious characters. Bellatrix Lestrange, Narcissa Malfoy, and Sirius Black are all descendants of Pollux Black, making them first cousins.
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.
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.
A member of the house of Black, one of the oldest wizarding families, Bellatrix was also Draco Malfoy's aunt. Renowned for her cruelty and sadistic nature, many of the acts of torture and violence against Voldemort's enemies were carried out by Bellatrix Lestrange.
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.
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.
When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her. Even her relationship with Draco is different, with POS-Narcissa only viewing Draco as a tool to further her own agenda.
Based on what Cursed Child lays out, Voldemort would become Draco's uncle (pretending he had married Bellatrix), thus Scorpius' great-uncle, making Delphi be Scorpius' cousin-once-removed.
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).
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.
Traits she shared with her father, aunt Walburga and cousin Sirius. She was also highly intelligent and interested in the Dark Arts from a young age. As a child and teenager she was rebellious and was often abused by her father who used memory charms on her, which caused and worsened her mental instability.
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?
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.
During this year, Narcissa became pregnant and miscarried. She was distraught and uncertain of what to tell Lucius, as she had not told him of her pregnancy. Shortly thereafter, he brought her out to the Leaky Cauldron to visit with his friends Vettlingar Yaxley and Thorfinn Rowle.
Lucius and his family defected at the end of the Second Wizarding War and were thus pardoned for their crimes after Voldemort's final defeat. He and Narcissa later had a grandson, Scorpius Malfoy, after Draco married Astoria Greengrass.
Narcissa, the youngest of all three, made a respectable marriage after graduating Hogwarts, and into another pure-blood family. It was Lucius Malfoy, a Death Eater, who brought Narcissa into the darker side of the wizarding world – but tellingly, Narcissa never became a Death Eater herself.
She placed Cedric's father Amos Diggory under a powerful Confundus Charm and made him think that she was his niece, despite neither Amos nor his wife having any siblings. When Amos was put into a nursing home for elderly Witches and Wizards, Delphi accompanied him and acted as his caretaker.
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.
Delphini "Delphi" Diggory is Voldemort's secret daughter (wow, the Potterverse is turning into a soap opera). She wants to resurrect the Dark Lord—not necessarily to bring evil to the world, but just because she wants to meet her dear ol' dad. It's actually kind of sweet…in a completely evil way. Ooh, dang.
