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.

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.
