County Commissioners' Records

The minute books of the County Commissioners contain interesting tidbits of history about the county as well as the names of individuals appealing to the County Commissioners for action on issues of concern to them. Minutes of those meetings were recorded from the formation of the county, for most counties. Some counties now post the minutes of current meetings online.

Most of these records have been preserved in the county courthouses of the State of Idaho. Few have been microfilmed. Contact the county clerk for information about years covered and availability.

Miscellaneous Series

Often overlooked by the genealogist, this group of volumes may contain affidavits for citizenship, final disposition of estates, divorce decrees, and many other types of valuable documents. The content varies from county to county, year to year and from clerk to clerk. When the estate case files, civil or criminal files are not available or have been destroyed, you may find key documents recorded here. Most counties will have an index to this series and it is a must search if the information you are seeking is not found elsewhere.
