Is Draco Related to Sirius? The Surprising Truth About the Black Family Tree

The Harry Potter series is full of fascinating characters, complex plots, and intriguing mysteries. One of the most intriguing aspects of the wizarding world is the genealogy of the pure-blood families, who are all interrelated in some way or another. One of the most prominent and ancient pure-blood families is the House of Black, which has produced many notable wizards and witches, both good and evil.

One of the questions that many fans have wondered is whether Draco Malfoy, the arch-rival of Harry Potter and a proud Slytherin, is related to Sirius Black, Harry’s godfather and a rebellious Gryffindor. The answer is yes, they are related, but not very closely. Here is how they are connected, and what it means for their characters and their relationship.

Draco Malfoy is the son of Lucius Malfoy and Narcissa Malfoy (née Black). Narcissa is the sister of Bellatrix Lestrange (née Black) and Andromeda Tonks (née Black). Sirius Black is the cousin of Narcissa, Bellatrix, and Andromeda. Therefore, Draco and Sirius are first cousins once removed.

This means that Draco’s grandfather, Cygnus Black III, was the brother of Sirius’s father, Orion Black. They also share a common ancestor in Phineas Nigellus Black, who was the great-grandfather of both Draco and Sirius.

The Black family tree is displayed in the drawing room of the family home at 12 Grimmauld Place in London, on an intricate tapestry that shows the dominant line of the family up to the death of its last members. The tapestry has many burn marks where the names of those who were disowned or deemed blood traitors by the family were removed. Some of these names include Sirius himself, Andromeda Tonks, Cedrella Weasley (née Black), and Marius Black.

What does their relationship mean for their characters?

Draco and Sirius have very different personalities, values, and allegiances. Draco is a spoiled, arrogant, and ambitious young wizard who believes in the superiority of pure-bloods and follows the Dark Lord Voldemort. Sirius is a brave, loyal, and rebellious older wizard who despises his family’s prejudice and fights for the Order of the Phoenix against Voldemort.

Despite their blood relation, Draco and Sirius have no affection or respect for each other. Draco sees Sirius as a traitor to his family and his cause, while Sirius sees Draco as a sniveling coward and a puppet of Voldemort. They have clashed several times throughout the series, both verbally and physically.

For example, in Harry Potter and the Prisoner of Azkaban, Draco mocks Harry for having Sirius as his godfather, calling him a murderer and a lunatic. Sirius later confronts Draco at Hogsmeade and threatens to kill him if he ever insults Harry again.

In Harry Potter and the Order of the Phoenix, Draco taunts Harry about Sirius’s death after he was killed by Bellatrix at the Department of Mysteries. Sirius had earlier fought against Draco’s father and aunt in an epic battle that resulted in his demise.

In Harry Potter and the Half-Blood Prince, Draco attempts to kill Albus Dumbledore on Voldemort’s orders, but is stopped by Harry and other members of Dumbledore’s Army. Sirius had once told Harry that he would rather die than betray Dumbledore.

What does their relationship mean for their relationship?

Draco and Sirius have no positive relationship whatsoever. They are enemies who share nothing but contempt and hatred for each other. They are on opposite sides of a war that has divided the wizarding world into light and dark. They are also rivals for Harry’s friendship and trust.

Harry Potter is very close to both Draco and Sirius, but in very different ways. Harry considers Draco as his nemesis, who constantly tries to sabotage him and make his life miserable. Harry also considers Sirius as his mentor, who gives him advice and support when he needs it most.

Draco and Sirius both influence Harry’s choices and actions throughout the series. Draco often challenges Harry to prove himself as a better wizard than him, while Sirius often encourages Harry to follow his instincts and stand up for what he believes in.

Draco and Sirius also represent two different paths that Harry could have taken in his life. Draco represents the path of darkness, where he would have succumbed to Voldemort’s influence and become a Death Eater. Sirius represents the path of light, where he would have resisted Voldemort’s power and become an Auror.


Draco Malfoy and Sirius Black are related by blood, but not by heart. They are first cousins once removed who belong to the noble and most ancient House of Black. However, they have nothing in common except their ancestry. They have different personalities, values, and allegiances that make them enemies in a war that has torn apart their family and their world. They also have different relationships with Harry Potter, who is the key to the fate of the wizarding world. Draco and Sirius are two sides of the same coin, but they will never see eye to eye.
