Parents:
* James Potter: Harry's father, a kind, brave, and talented wizard. James was a member of the Marauders, a group of close friends who were also Hogwarts students. He was known for his prankster tendencies and loyal friendship with Sirius Black. He was tragically murdered by Lord Voldemort when Harry was only a year old.
* Lily Potter (née Evans): Harry's mother, a powerful witch with a strong moral compass. Lily was a close friend of Severus Snape and a Gryffindor, much like her husband. She was also killed by Lord Voldemort when he attempted to kill Harry.
Guardian:
* Rubeus Hagrid: While not blood-related, Hagrid is a pivotal figure in Harry's life. He is a half-giant who acts as Harry's guardian after his parents' death. He delivers the news of Harry's magical heritage and brings him to the Dursleys. Hagrid is a loyal friend and mentor, providing Harry with a sense of family.
Aunt, Uncle, and Cousin:
* Petunia Dursley (née Evans): Harry's aunt, Lily's older sister. Petunia is a bitter and envious woman who resents Harry's magical abilities and disdains her late sister. She treats Harry poorly, denying him basic kindness and affection.
* Vernon Dursley: Harry's uncle, Petunia's husband. Vernon is a pompous and arrogant man, obsessed with maintaining a "normal" life and deeply prejudiced against anything magical. He is cruel to Harry and seeks to keep him isolated from the wizarding world.
* Dudley Dursley: Harry's cousin, Vernon and Petunia's son. Dudley is spoiled, selfish, and bullies Harry throughout their childhood. He is a symbol of everything Harry is not and represents the mundane world that Harry struggles to escape.
Other Important Relatives:
* Sirius Black: Harry's godfather, a member of the Marauders and a close friend of Harry's parents. Sirius is falsely accused of betraying James and Lily, and spends years in Azkaban prison. He becomes Harry's guardian after Hagrid and helps him understand his parents' legacy.
* Remus Lupin: Another member of the Marauders, Remus is a werewolf who was a close friend to Harry's parents. He becomes Harry's Defence Against the Dark Arts teacher and helps him learn more about the past.
* The Weasley Family: Arthur and Molly Weasley, with their children, are like a second family to Harry. They offer him love, support, and acceptance. Harry's friendship with Ron Weasley is a central element in the books.
Additional Note: Harry's ancestry is not just limited to the people mentioned above. He has a long lineage in the wizarding world, including powerful and influential families like the Potters and the Blacks.
