The Harry Potter family tree is the web of blood relations, marriages, and magical lineages that connects the main characters of J.K. Rowling’s series, centering on the Potter, Weasley, Black, and Granger families. The most complete and accurate version comes from the books, the films, and Rowling’s own supplemental writings, especially the Black family tapestry and interviews.
The Potter Family Line
The Potter surname is an English name, and the family has been pure-blood for generations, though they are known for their tolerance of Muggle-borns. The earliest known Potter in the series is Linfred of Stinchcombe, a medieval wizard who invented Skele-Gro and Pepperup Potion, earning the nickname “the Potterer.” His descendants took the name Potter.
- Hardwin Potter married Iolanthe Peverell, granddaughter of the eldest Peverell brother (from the Deathly Hallows tale), which is why the Potters carry the Invisibility Cloak.
- Fleamont Potter and Euphemia Potter were James Potter’s parents. Fleamont invented Sleekeazy’s Hair Potion and made the family fortune.
- James Potter married Lily Evans, a Muggle-born witch. Their son is Harry James Potter.
- Harry married Ginny Weasley and had three children: James Sirius, Albus Severus, and Lily Luna.
Note that the name “James Sirius” honors both Harry’s father and his godfather, Sirius Black.
The Black Family Tree
The Black family is an old pure-blood dynasty, and their tree is famously displayed on a tapestry in the series. It includes many characters connected to Harry’s world.
- Phineas Nigellus Black was a former Hogwarts headmaster and great-great-grandfather of Sirius.
- Walburga Black and Orion Black were Sirius and Regulus’s parents.
- Sirius Black was Harry’s godfather. He had no children.
- Regulus Arcturus Black was a Death Eater who defied Voldemort and died trying to destroy a Horcrux.
- Bellatrix Lestrange (née Black), Andromeda Tonks (née Black), and Narcissa Malfoy (née Black) were sisters, daughters of Druella and Cygnus Black.
- Andromeda married Muggle-born Ted Tonks; their daughter Nymphadora Tonks married Remus Lupin and had a son, Edward “Teddy” Lupin.
- Narcissa married Lucius Malfoy; their son is Draco Malfoy.
Because the Black family disowned members who married non-pure-bloods (like Andromeda and Sirius), the tapestry has burn marks over their names.
The Weasley Family Tree
The Weasleys are a large pure-blood family, and they become Harry’s surrogate family. The known tree starts with Septimus Weasley and Cedrella Black (who was disowned for marrying him). Their son Arthur Weasley married Molly Prewett.
- Arthur and Molly had seven children: Bill, Charlie, Percy, Fred, George, Ron, and Ginny.
- Bill married Fleur Delacour; they had three children: Victoire, Dominique, and Louis.
- Percy married Audrey; they had two daughters: Molly and Lucy.
- Fred died in the Battle of Hogwarts; he had no children.
- George married Angelina Johnson; they had a son Fred (named after his twin) and a daughter Roxanne.
- Ron married Hermione Granger; they had two children: Rose and Hugo.
- Ginny married Harry Potter (see above).
The Weasley family is notable for being pure-blood but rejecting blood purity ideology.
The Granger Family and Muggle Connections
Hermione Granger is a Muggle-born witch, meaning both her parents are non-magical. Her parents are Mr. and Mrs. Granger (first names never given in the books; in the films they are Richard and Helen, but that is not canon). They are dentists. Hermione marries Ron Weasley, making the Granger family part of the extended magical family tree.
Similarly, Harry’s mother Lily Evans was Muggle-born, and her sister Petunia Dursley married Vernon Dursley. Their son Dudley Dursley is Harry’s only cousin on his mother’s side.
Other Key Branches and Marriages
Several other families connect to the main tree through marriage:
- Delacour: Fleur Delacour marries Bill Weasley, linking the French Beauxbatons family to the Weasleys.
- Tonks: Andromeda Black marries Ted Tonks, linking the Black line to a Muggle-born.
- Lupin: Remus Lupin marries Nymphadora Tonks; their son Teddy is Harry’s godson.
- Malfoy: Narcissa Black marries Lucius Malfoy; Draco Malfoy marries Astoria Greengrass and they have a son, Scorpius.
- Dumbledore: Albus Dumbledore’s family is not directly connected to the Potter tree, but his brother Aberforth has a daughter (unnamed in the books).
Note that the series never gives a complete tree for every family; Rowling released some family details on Pottermore (now Wizarding World).
Common Misconceptions
Many fans wonder about relations that are not actually in the books:
- Is Harry related to Voldemort? No. Voldemort (Tom Riddle) is a descendant of the Peverell family through his mother’s line (the Gaunts), and the Potters also descend from the Peverells, but this is a distant, shared ancestor from centuries ago, not a close relation.
- Are the Potters related to the Blacks? Not directly. The only connection is through marriage: Harry’s grandmother (Euphemia) is not a Black; the Black connection comes from the Weasley side (Cedrella Black married Septimus Weasley).
- Is Hermione related to anyone magical? No, she is Muggle-born, so her family tree is entirely non-magical.
- Did Sirius have a child? No, he died without heirs.
Frequently Asked Questions
Who are Harry Potter’s grandparents?
Harry’s paternal grandparents are Fleamont and Euphemia Potter. They died before Harry was born. His maternal grandparents, Mr. and Mrs. Evans, also died before the series begins; they are mentioned in passing.
How is Harry Potter related to Sirius Black?
Sirius is Harry’s godfather, not a blood relative. He was James Potter’s best friend. However, through the Black family tree, Sirius is related to the Weasleys (Cedrella Black is Arthur Weasley’s mother), so after Harry marries Ginny, there is a distant in-law connection.
Is Draco Malfoy related to Harry Potter?
No, Draco and Harry are not blood relatives. Draco’s mother Narcissa is a Black, and the Black family is not connected to the Potters by blood. They are enemies by choice, not by family tie.
What happened to the Black family after Sirius died?
Sirius had no children, so the direct Black line ends with him. The family name continues through the female line only if married names are ignored; the last known Black descendants are Draco Malfoy (through Narcissa) and Teddy Lupin (through Andromeda’s line).
Are the Weasleys related to the Potters before Harry and Ginny marry?
No. The Weasleys and Potters are not blood relatives until Harry marries Ginny. The only connection is through friendship and the Black family (Cedrella Black is Arthur’s mother, but she is not a Potter).
Who is the oldest known ancestor in the Potter family tree?
The oldest named Potter is Linfred of Stinchcombe, a medieval wizard. Rowling wrote that he lived in the 12th century, but the exact dates are not given in the books.
