Guides to County Records

The Archives of Michigan holds extensive local government records representing all of Michigan’s 83 counties. These county records can include tax assessments, naturalizations, probate files, poor house registers, circuit court case files, occupational certifications, and more. Holdings may vary widely from county to county.

Below is a listing of Michigan county guides detailing what records are available for each county. The records listed are available at the Archives of Michigan in Lansing or housed at our repository partners closer to the county. (Records held elsewhere are noted on the guides.)

Be sure to utilize the Archives of Michigan’s online catalog to learn more about the collections listed in these guides. A keyword search using the phrase “[county name] county,” provides another way for researchers to identify Michigan county records of interest.
