  1. Teri Wells says:

    This is really interesting. Why was Frederick Aikens grave unmarked. Was he still hated after a decade had passed. How many of Lincoln’s general’s actually liked him. We know McClellan and Lincoln never got along. Also in the movie theConspirator was that true Mary Surratt ‘s son giving the rosary to the lawyer. I wonder what happened to it?
