On March 26, 1846, a small sliver of the westernmost portion of Corydon bordering the Allegheny River was transferred to Warren County; the new township also retained the name Corydon, resulting in there being two adjacent but separate townships with the same name.

Charles F. Freeman, Wisconsin politician and businessman, was born in the township.

[3] Ray Caldwell, baseball star of the early 20th century, was also born in Corydon.

26.2% of all households were made up of individuals, and 9.8% had someone living alone who was 65 years of age or older.

About 8.7% of families and 9.8% of the population were below the poverty line, including 9.9% of those under the age of eighteen and 14.3% of those sixty five or over.
