Merope Riddle (née Gaunt), (c. 1907 – 31 December, 1926) was apure-blood witch, daughter of Marvolo Gaunt, and sister of Morfin. She was a direct descendant of Salazar Slytherin and a Parselmouth. Merope lived in a shack with her father and brother, who mentally and physically abused her. Later on, Merope grew to have an obsessive love for Tom Riddle, a handsome and wealthy Muggle. When both her father and brother were imprisoned, she bewitched and married Tom, but when he recovered, he abandoned her and their unborn son. Merope ended up dying at an orphanage, soon after giving birth to her son, whom she had named Tom Marvolo Riddle.
Many years later, her son, with the name of Lord Voldemort, became the most dangerous Dark wizard of all time.
