Billings boundary in 1887Today's boundaryBoundaries: Newberry Library, Atlas of Historical County Boundaries

The Atlas data for Billings County begins in 1887, later than the 1879 date above, so this is the earliest boundary on file, not its original one.

Records stay with the county that created them. If your ancestor lived here before 1879, search the parent county. The Atlas of Historical County Boundaries shows each boundary change.

Research tip

Until 1889 North and South Dakota were one territory, so early records may be filed under Dakota Territory. Many settlers claimed land under the Homestead Act; their federal case files are at the National Archives.
