Mary Lincoln's presence at Abraham's death-bed

[Donna McCreary]

Can anyone verify if Dr. Lyman Beecher Todd was at the Peterson Home that evening? I've read in several of the Todd family papers that he tended to Lincoln that evening. He was in Washington DC and shortly after Lincoln's death LBT sent several telegrams on Mary's behalf. If he was not in the room when Lincoln died, I wonder if he could have been tending to "Cousin Mary."
