Mary Black was a slave of African descent in the household of Nathaniel Putnam of the Putnam family who was accused of witchcraft during the Salem witch trials. Nathaniel's nephew was Thomas Putnam, one of the primary accusers, though Nathaniel himself was skeptical and even defended Rebecca Nurse. Mary was arrested, indicted, and imprisoned, but did not go to trial, and was released by proclamation on January 21, 1693 [O.S. January 11, 1692]. She returned to Nathaniel's household after she was released, another indication of Nathaniel's view of the charges against her.
