Lexington was founded by Amariah Watson, Jr. in 1814, a land speculator who had purchased wide lands locally in order to sell to other settlers. During the 1800s, Lexington had many taverns, hotels, and grist mills — most of which at one time or another burned to the ground. In the 19th century, leading members of the community were William Cockley Thad and Martin Kell, Les Griebling, Erwin Castor, Sgt. Patrick Gass, and Jacob Cook. The first road constructed through town was what is now State Route 97, and the second was what is now Lexington-Ontario Road. (From Robert A.
