Great grandfather was called to DC by Sec Stanton to run the investigation of Lincoln's assassination since he'd gotten the death penalty for the southern conspirators in IN. Most of the records are in his handwriting, so I bought a lot of the microfiche. Then he was one of the special judge advocates for the trial, and put together the records for the library of congress. Staunch Republican who was the DA for the So District of NY for 2 terms. I got his grave taken over by a CW re-enactors group in NY, and one of the park rangers called to play ggf in Ford Theatre. He was a passionate supporter of Judge Holt and General Hancock, who both got very bad press after the trial.
