I don't have a Mortecai Dickens, but I do have information on Eli S. Dickens and would like to trade data with you. I do not have any Dickins.
Dickens is on my wife's side of the family line and married into her Rothermich line. Rothermich married into the Lyon line, which is my wife's maiden name.
