DeWitt County is located in central Illinois. It was formed in 1839 from Macon and McLean Counties. It was named for the seventh Governor of New York, DeWitt Clinton, and the county seat is the city of Clinton.
Birth and death records have been kept since 1878. Marriage records, Probate files and Land Records date to the founding of the county. Many of the early records may be found on FamilySearch.org.
These records may also be requested in writing from the County Courthouse at 201 W. Washington St., Clinton, IL 61727. Records are also found at the IRAD depository at Illinois State University. In addition to vital records, the IRAD has naturalization records and Justice of the Peace dockets.
