Black Alone

Helene Lyra Black has known for years her father was a Death Eater, but had betrayed them, and that was why no one in the family would adopt her. She knows that her mother died during childbirth, and her father was already dead before that. She never knew who her mother was. Her uncle, Sirius Black had been supposed to adopt her. He then got convicted of murder and sent to Azkaban. In the end, she grew up in Northern California, living with a random muggle, knowing nothing of the Wizarding World.
