Welcome to Harry Potter Answers. What would you like to know?

Harry Potter's father, James Potter, was a pureblood and so was Sirius. All purebloods are related. Sirius and Harry may have been second cousins or they were more distant cousins. Sirius' great aunt married a Potter so there is no doubt that Harry and Sirius are related in someway.
