Organized January 2, 1833, from Ray County and named for Charles Carroll of Carrollton. At the organization of the county the intention was to call it "Wakanda," after the river of that name already referred to, and the bill forming the new county had passed its first and second reading by that name, but when it came up for its third reading and final action, the news of the death of Charles Carroll, of Carrollton, the last surviving signer of the Declaration of Independence, had just been received in Jefferson City, and in lieu of Wakanda, it passed without a dissenting vote, and was signed the 3d day of January, 1833, the county having been laid off in townships in 1816, and sectionalized in 1817
