The Goblins, interestingly enough, wanted Harry to to a full inheritance test. Much to his surprise, he was the heir to much more than just the Potter vaults. He also held the lordships of Peverell, Black and Gryffindor. Black was not by blood, so he could not use it in the 40’s, but Gryffindor and Peverell were so, along with everything within the many vaults, they kept the newfound information in the backs of their minds. Now, having succeeded, Hermione wondered if perhaps the Peverells had been without an heir for over fifty years. If there were none in this time, Harry could claim the lordship, which would work much to their advantage.
