From Quiz It's a Grand Old Name
Answer:
Mary Surratt
Mary Surratt, a widow, ran a boarding house in Washington, D.C. and John Wilkes Booth, Lincoln's assassin, was a frequent visitor. Mary's son, John Surratt Jr., was a Confederate spy and messenger, and a friend of Booth's. According to the not altogether reliable (in my view) testimony of John M. Lloyd, Mrs. Surratt was charged with seven others as a co-conspirator in the Lincoln assassination plot. She was hanged on July 7, 1865, with three of the men charged in the crime, and took her place in history as the first woman executed by order of the United States Government. Mudd, Herold and Paine were also charged as co-conspirators, but they were all men, none of whom was named Mary.
