The Mysteries of Harry James Black

Harry Potter went to his vault at Gringotts on his 16th birthday after clearing Sirius Black's name and gets handed a copy of his birth certificate by the goblins there. However, everybody is shocked to see that it states in bold 'Harry James Black', and under the parents' section, it states Mother: Lily Evans-Potter, Father: Sirius Orion Black. It isn't long before the rest of the world finds out, and Harry's life is turned upside down.
