Etymology - Origin of Carroll County Name

Carroll County was organized in 1839, and was named for Charles Carroll, a wealthy landowner and politician from Maryland. He was one of the men who signed the Declaration Of Independence, and incidentally, was the last of the signers to die. The honor of naming the county was bestowed upon Isaac Chambers, the first settler in the county. Since Charles Carroll was one of the political heroes of the day, and since many settlers were from Maryland, Mr. Chambers decided to name the county after him.
