Grave of Mary Surratt, executed by hanging on July 7, 1865, for her role in the conspiracy to assassinate Abraham Lincoln. The original headstone (which was quite similar to this, although slightly more decorative at the top) was defaced and broken by 1968. It was replaced with a large, orate one wit a big brass plaque asserting her innocence. At some point in the 1980s or 1990s, the Surratt Society replaced it with an approximation of the original headstone.
To the left and right of the grave, in unmarked plots, lie Surratt's children, Isaac and Anna. Her other child, John Jr. (who was John Wilkes Booth's co-conspirator) is buried in Baltimore, Maryland.
