Once separate villages, Cedarville was platted in 1838, and Leo was founded in 1849, originally as the Town of Hamilton.

[citation needed] The Hursh Road Bridge was added to the National Register of Historic Places in 1981 and delisted in 1993.

[8] The town is served by East Allen County Schools.
