Hufflepuff is the surname of a wizarding family that existed circa one thousand years ago in Britain. It is unknown if they were pure-blood, or if they had Muggle as well as magical heritage. It is also unknown if this family is extinct in either the male or female line, though the Hufflepuff name is well known, as Helga Hufflepuff was the founder of Hufflepuff house at Hogwarts School of Witchcraft and Wizardry.
