Mary Lou Barebone[5] (d. 7 December, 1926) was an American No-Maj who lived in the 20th century.[2] She was born into the Barebone family, a family that descended from one of the Scourers who evaded justice in the late 17th century by integrating into No-Maj society. Mary Lou was marked by a profound belief in the existence of magic and an equally deep hatred of it. She was the leader of the New Salem Philanthropic Society, also known as the Second Salemers, an extremist group whose goal was to expose and eradicate witchcraft in the United States.[2][4][6] She had three adopted children:[5] Chastity, Modesty, and Credence.[5][7] Mary Lou died on 7 December, 1926 at the hands of Credence's unleashed Obscurus. She was violently flung against the rafters in the chapel of the Second Salem Church and fell dead with formidable marks covering her face.
