Where to find the records

Offices change their hours and access rules; call before you visit.

Boundaries and parent counties

Formed from: Tuality District (now Washington County)

Check the parent county for earlier records: Washington County

Later formed partly from Clatsop County: Tillamook County

Records stay with the county that created them. If your ancestor lived here before 1844, search the parent county. The Atlas of Historical County Boundaries shows each boundary change.

Research tip

Settlers who reached Oregon by December 1, 1855 could claim land under the Donation Land Claim Act of 1850 and its amendments; the earliest arrivals could claim the most. The claim files, at the National Archives, often give a settler's birth date and birthplace and the date and place of a marriage, because a married couple could claim twice as much land. Earlier provisional government land claims (1845–1849) are at the Oregon State Archives.
