Carroll County was originally part of Columbiana County, until it was authorized on December 25, 1832. The county was named after the last surviving signer of the Declaration of Independence, Charles Carroll, who was born in Annapolis, Maryland. Carroll died on November 14, 1832 at the age of 95. Carroll County has a rich historical narrative going back to the American Revolution, and was continuously used as a gateway to the West. Though there are only three Ohio Historical Markers, there are multiple County Markers put up regarding other historic people, events, and sites.
