The Daughter of Sirius Black. (BEING EDITED)...
Mary Lily Alison Dragonwood is the daughter of Sirius Black and Lucy Dragonwood. Lucy got pregnant with Mary, when she was engaged to Sirius, Lucy never told Sirius that she was pregnant, but she did tell her best friends Lily Potter and Alice Longbottom.
The night Lucy went to tell Sirius that he was going to be a father, something dreadful happened that made it so Sirius never found out about Lucy being pregnant.
It was the night that Lucy lost her best friend Lily Potter, it was also the last night she saw Sirius.
Fast forward 15 years and Mary is at Hogwarts, and she is a 3rd year Ravenclaw. Lucy has not told Mary anything about who her father is, and Lucy never told anyone other then her two best friends about who Mary's father is, but those two friends are no longer there to help her. Lucy does her best to keep Mary from finding out who her father is.
But what happens when Lucy goes missing? And Dumbledore takes Mary to Number Twelve, Grimmauld Place to keep her safe till it is time to go back to Hogwarts?
You'll have to read and find out.
