The Village of Ansonia is a small, rural community in west central Ohio. Located in northern Darke County at the intersection of State Routes 47 and 118, the Village is just 7 miles north of the City of Greenville.

Platted in 1845 by John Baughman, The Village was incorporated in 1867 as the Village of Dallas. A Post Office was established in January,1853 as the Ansonia Post Office since a Post Office named Dallas already existed in Highland County. As the story goes, the first Postmaster, George A. Turpen, selected the name Ansonia from the clock on the wall in the Post Office that was manufactured by the Ansonia Clock Company in Ansonia, Connecticut. The clock still exists and is keeping time in the present Post Office.

In 1885 the name of the Village was changed to Ansonia so that the name of the Village and its Post Office were the same and to avoid confusion with the "other" Dallas. The Dallas Post Office, which was located in the Village of Boston, remained in operation until April, 1905.
