Presence at assassinations

There is coincidence in regard to Lincoln and presidential assassinations. He was either present or was nearby when three of them occurred. [4]

    * Lincoln was invited to accompany his parents to the Ford's Theatre the night his father was shot by John Wilkes Booth on April 14, 1865. Citing fatigue from riding in a covered wagon for an extended period of time, he declined and remained behind at the White House, where he immediately went to bed. He was informed of the President's being shot just before midnight.

    * At President James A. Garfield's invitation, Lincoln was at the Sixth Street Train Station in Washington, D.C., where the President was shot by Charles J. Guiteau on July 2, 1881 and was an eyewitness to the event. Lincoln was serving as Garfield's Secretary of War at the time.

    * At President William McKinley's invitation, Lincoln was at the Pan-American Exposition in Buffalo, New York, where the President was shot by Leon F. Czolgosz on September 6, 1901, though he was not an eyewitness to the event.


and

odd coincidence, Robert Lincoln was once saved by Edwin T. Booth, brother of John Wilkes Booth, from possible serious injury or death.
