1890 Oklahoma Territorial Census

The OHS Research Center created an index to the 1890 Oklahoma Territorial Census. Most of the 1890 US Federal Census was destroyed by fire in 1921, making the 1890 Oklahoma Territorial Census one of the few remaining census records from the time. The Oklahoma Historical Society Research Division collections include the original census pages.
