The wand of Mary Cattermole was 8¾" cherry wood, with a unicorn hair core. She purchased it from Ollivanders in Diagon Alley when she was eleven years old. In 1997, after Lord Voldemort took over the Ministry of Magic, the Muggle-Born Registration Commission was created to prosecute Muggle-borns for supposedly stealing wands from "real" wizards and witches. Mary was one such innocent who was interrogated by the head of the commission, Dolores Umbridge, and Death Eater Yaxley. They accused her of stealing her wand. The trial was soon interrupted by Harry Potter and Hermione Granger, who freed Mary and the other Muggle-born prisoners along with Ron Weasley and encouraged them to flee the country. It is unknown if she ever retrieved her wand after the war.
