Source: Missouri State Archives, Guide to County and Municipal Records on Microfilm. Recorder of deeds records dated 1970 or later must be requested from the county.

- The recorder of deeds
Deeds and mortgages, and marriage records, usually from the county's beginning. Licenses were required from 1881; earlier books record the marriages themselves.

- The circuit clerk
Civil and criminal cases, divorces and, in many counties, naturalizations.

Boundaries and parent counties
Formed from: Land not yet in any county
Records stay with the county that created them. If your ancestor lived here before 1838, search the parent county. The Atlas of Historical County Boundaries shows each boundary change.
Research tip
Missouri's probate files often hold far more than a will: inventories, sale bills listing the buyers (often relatives and neighbors) and the receipts of heirs. Check the circuit court too, where heirs went to divide land.
