For Arthur, it all started with the Sorting Hat. It gave him an identity. Unlike some pure-blood families, Arthur’s brothers were scattered around the houses. Two of his brothers resided in Gryffindor, one in hufflepuff, and the last one in Ravenclaw. Even before his oldest brother went to Hogwarts, it was already clear they wouldn’t end up in the same house.
