Lincoln's Sons

[Eva Elisabeth]

I've also read somewhere that poor Tad was called to testify at the Surratt trial. How awful for him!

Toia, I remembered your post when reading this - according to p. 378 of "A True History of the Assassination of Abraham Lincoln" by Louis J. Weichmann/A. C. Richards, Tad said after the trial to Louis Weichmann: "I desire to thank you, sir, for your testimony in behalf of my father." "Who are you, sonny?" Weichmann asked. "My name is Tad Lincoln."

Tad testified at the John Surratt trial on Friday, July 5, 1867. Here's the entire trial transcript (see p.525-526):
