Harry Potter (character) [SEP] Family tree
In the novels, Harry is the only child of James and Lily Potter, orphaned as an infant. Rowling made Harry an orphan from the early drafts of her first book. She felt an orphan would be the most interesting character to write about. However, after her mother's death, Rowling wrote Harry as a child longing to see his dead parents again, incorporating her own anguish into him. Harry is categorised as a "half-blood" wizard in the series, because although both his parents were magical, Lily was "Muggle-born", and James was a pure-blood. Harry's aunt and uncle kept the truth about his parents' deaths from Harry, telling him that they had died in a car crash.
