Where was John Surratt on April 14, 1865 ?

[RJNorton]

Many books cite John Surratt's Rockville lecture but fail to mention he also gave two more. During December 1870 Surratt gave a second lecture at the Cooper Union in New York City and a third one at Concordia Hall in Baltimore, but these events were not well attended. Many thanks to Steve for sending this article about the Baltimore lecture. It is from page 1 of the December 30, 1870, issue of the Baltimore Sun.
