Census
For a summary of census records for the state of Idaho, see Idaho Census Records.

The 1890 federal census for Idaho was destroyed. However, the Idaho State Archives is creating a list of 1890 Idaho residents by indexing a variety of records, 1885-1894. This reconstructed list will substitute for the destroyed 1890 federal census. Boise County is included in this reconstructed census.

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.
