History

The first plat of the town was started in 1854 by a Dr. Moore and named after his eldest daughter “Cora”, but the name was never recorded. In 1855 a Mr. Gibbs arrived from Massachusetts, representing wealthy capitalists in Massachusetts and Connecticut. He prevailed upon Mr. Orrin Sage, a great banker from Ware, MA to invest in this community, and later Mr. Sage gave $2,000 and 600 acres of land to the Library Building Fund.

A Subway sandwich shop occupies the ground floor of the building today and the date of 1876 along with “Sage Library” is seen in the concrete and brick work of the second story.
