Martine Copplestone was a Hufflepuff student at Hogwarts School of Witchcraft and Wizardry in the 1990s. She was seen walking around the school in the 1993-1994 school year. Some people considered her nosy, as she often used the Levitation Charm to lift objects, in order to find things hidden underneath. She told Harry Potter about this trick during the 1996–1997 school year.
