Access Adams County Genealogy
Adams County genealogy records include marriage files dating back to 1825, making them some of the oldest county records in Illinois. The county seat is Quincy, where the clerk holds vital records and the circuit court keeps probate and case files. Birth records start in 1878 and death records are also on file. A fire on December 9, 1835 destroyed some early records, so there are gaps in certain collections from the earliest years. You can search Adams County records at the clerk office in person or by mail. Older files sit at the IRAD at Western Illinois University in Macomb. Adams County is in the western part of the state along the Mississippi River, and its long record history makes it a valuable stop for genealogy researchers.

Adams County 1835 Fire and Record Gaps
The fire of December 9, 1835 is an important fact for anyone doing genealogy in Adams County. The fire destroyed the courthouse and some of the records inside. The full extent of the loss depends on the record type. Marriage records from the 1825 to 1835 period may have gaps. Other court records and land files from those early years may also be missing or incomplete.
If you are looking for Adams County records from the 1825 to 1835 period, be prepared for the possibility that they do not exist. In some cases, copies or duplicates survived because they were stored somewhere else. Church records from Quincy and surrounding communities can sometimes fill in what the county lost. Census records from 1830 also help piece together family information from that era. The Illinois State Archives may hold fragments or related documents that survived the fire. It is worth checking their free online databases for any Adams County data from that time.
