I am a descendent of Alexander Aikman and Mary Elizabeth Lewis. I have John Aikman who married Hannah Showers possibly linked to my Alexanderas a son of my Alexander. I am quite well documented from my Alexander on down through his daughter Elizabeth.. I am interested in what book you are referring to. I have seen books in Columbia Co PA about Aikmans. Elizabeth married John Hutchison and her sister Mary married James Hutchison his brother. they left PA in early 1830's for Michigan.
