Have found new information that William Lyman Born 1803 married Mary Jane McKay born 1813, not Elizabeth Matteson. When William Lyman died about 1834 she married Thomas Dunn son of Oliver Dunn. They are found in the census of 1850 in Fairview Twp. Her children, William G. and Benjamin,and their children lived with them. I have tintypes of some of the McKay's and Dunn children which I have scanned. Some of the McKay migrated to Decorah, Iowa and the Dunn's to Monmouth, IL.
Who is the father of this William Lyman? He is not part of the Prussian family.
