U.S. States: New York: Chenango County
I have another Iowa connection for you.
Berton Alcott (my wife's grandfather) who was the great grandson of Benjamin Elmar , via Enos and Almon) studied optometry, and became a traveling optometrist - in Iowa!
On Nov. 30, 1905 he married Mary Ann McCormack of Hanover township, near Waukon, Iowa, which is only about 60 miles from Delaware. (By train the journey would have been much longer, via Marquette and Dubuque.)
However he settled down, establishing a practice in Whitewater, Wisconsin, lived there until his death in 1955. He and Mary Ann are buried in Iowa, however.
