Mary Surratt
Mary Surratt (1823 - July 7, 1865) was a co-conspirator in the Lincoln assassination plot. After John Wilkes Booth was shot and killed, she and three others involved in the plot became the focus of the grieving nation's wrath and were sentenced to death by hanging. Surratt was the first woman ever executed in the United States, and some of her co-conspirators swore that she was innocent.
