Clarence Avery (born c. 1926) was a wizard and a Slytherin student at Hogwarts School of Witchcraft and Wizardry. He was a member of Tom Riddle's gang when they attended Hogwarts, and was a member of the Slug Club. He has two sons, each of a marriage. One of his sons became a Death Eater like him, the other other just a follower of Voldemort.
