I would suggest that it would not be possible if he made it to America.
Firstly, if he had been charged with embezzlement, I doubt if he would have gone anywhere except goal.
If he had stolen, but made good his escape to America, there would be no records for you to trace.
Your only hope would lie in newspaper reports of the time.
Good luck! My family is littered with family rumors of connection to Earls, Lords etc, and so far they have all proved to be nice folklore without one grain of truth, but you never know do you?
