Henry Reed Rathbone (July 1, 1837 – August 14, 1911) was a United States military officer and diplomat who was present at the assassination of President Abraham Lincoln.
 Rathbone was sitting with his fiancée, Clara Harris, next to the President and his wife, Mary Todd Lincoln, when John Wilkes Booth entered the president's box at Ford's Theatre and fatally shot Lincoln in the head.
 When Rathbone attempted to prevent Booth from fleeing the scene, Booth stabbed and seriously wounded him.
Finis Langdon Bates (August 22, 1848 – November 29, 1923) was a Memphis, Tennessee, lawyer and author of "The Escape and Suicide of John Wilkes Booth" (1907).
 In this 309-page book, Bates claimed that John Wilkes Booth, the assassin of U.S. President Abraham Lincoln, was not killed by Union Army Soldiers on April 26, 1865, but successfully eluded capture altogether, and lived for many years thereafter under a series of assumed names, notably John St. Helen and David E. George.
The Mary E. Surratt Boarding House in Washington, D.C. was the site of meetings of conspirators to kidnap and subsequently to assassinate U.S. President Abraham Lincoln.
 It was operated as a boarding house by Mary Surratt from September 1864 to April 1865.
The Lincoln assassination flags were the five flags which decorated the presidential box of Ford's Theatre, and which were present during John Wilkes Booth's assassination of U.S. President Abraham Lincoln on April 14, 1865.
 Lincoln and his wife, Mary Todd Lincoln, were in this box watching a production of "Our American Cousin".
 Booth's spur was allegedly caught by one of the flags when he began his escape from the theatre and broke his leg; this part of the story, however, is disputed.
 Three of the flags were American flags and the other two were Treasury Guard flags.
 According to Civil War historians, three of these five original flags are currently accounted for.
