Amy Benson

From Harry Potter Wiki

Amy Benson was a resident in the orphanage that Tom Riddle (later Lord Voldemort) resided in as a child. Tom took her and Dennis Bishop to a cave near the spot where the orphanage kids were taken on vacation. After the trip inside the cave, she and Dennis did not act the same and seemed strange. Tom seemed to have done something so terrible inside the cave that the two orphans were frightened into silence.
