Roger Mudd’s grandfather—or something like that—was implicated in the Lincoln assassination and put to death. He was a doctor and fixed Booths leg. Mudd, was put to death. “Your name is Mudd” is thought to come from that.
Not telling anyone anything they didn’t know? Well, how about this, John Wilkes Booth was in Buffalo on the Fourth of July 1863, when Gettysburg was going on. He was an actor and many people liked him, they threw benefits in his honor. At that same time Father Baker was boarding a train to join the army in an emergency role to face Lees invasion of the north.
I also found out that that one of the guys who hunted down and killed Booth lived on Saranac Avenue in Buffalo not far from where I grew up.
