Just to close out one of the questions on this one, I've now seen the Horton Asylum case notes (Thanks Alison !) and the descriptions of the scars on the back of the neck and the outside of the right leg match the prison description from Sing Sing. So it is the same man.  Our thanks to everyone who contributed to this thread.
 
We still haven't identified "Miss O'Donnell" though.
