Carroll County is located in north-central Kentucky along the Ohio River. It is one of the smallest counties in the State. It was formed in 1838 from portions of Gallatin, Henry, and Trimble Counties.
Both Carroll County and its county seat, Carrollton, were named for Charles Carroll, a U.S. Senator for Maryland. Of all who signed the Declaration of Independence, Charles Carroll (1737‑1832) lived the longest. There are Carroll Counties in 12 states and two Parishes in Louisiana, all named for Charles Carroll.
