Spotlight on Carroll County, Illinois

Carroll County is located in northwest Illinois.  It was formed in 1839 from Jo Daviess county. It was named for Charles Carroll, a Marylander who signed the Declaration of Independence.  Although Mr. Carroll never set foot in Illinois, many of the county’s early settlers were from Maryland.  The county itself remains fairly rural and they boast of only one stoplight in the entire county.

Birth and death records have been kept since 1877.  Marriage records, Probate files and Land Records date to the founding of the county.  Unfortunately, few records are accessible on FamilySearch.  There are some early vital records online at, along with some obituaries and cemetery information.

The courthouse is located in the county seat of Mt. Carroll and their website is  Some vital records may also be found at the IRAD depository at Northern Illinois University. Other county records housed at the IRAD are land, probate, and naturalizations records.

The Carroll County Genealogical Society has some church records online as well as records of naturalizations, and county poor farm records. They may be reached at
