Tillamook County Genealogy
Tillamook County sits on the northern Oregon coast, where dense forests meet the Pacific Ocean. Genealogy research here reaches back to 1853 and draws from land claims, court files, and vital records kept at the county seat in the city of Tillamook. Searching through these archives uncovers the stories of dairy farmers, timber workers, and coastal settlers who built their lives along the bays and rivers of this green and rainy region.
Tillamook County History and Records
Tillamook County formed in 1853. It took its name from the Tillamook Indians who had lived along the coast for centuries. The county seat is the city of Tillamook, which grew up around Tillamook Bay. Early settlers came by sea or over rough mountain trails. Roads through the Coast Range were poor, and the county stayed cut off from the Willamette Valley for years.
That isolation shaped the records. Tillamook County kept its own detailed logs because help from other parts of the state was far away. The clerk recorded deeds, marriages, and court actions from the very start. Land claims from the 1850s name the first white settlers in the area. For Tillamook County genealogy, these early records are a direct link to the founding families of the region.
Timber and dairy were the two pillars of the local economy. Old-growth forests covered the hills. Sawmills sprang up along every creek. At the same time, the mild climate and heavy rainfall made the lowlands perfect for dairy cattle. These two industries left a rich paper trail. Mill pay rolls, timber sale contracts, and dairy cooperative records all name people who lived and worked in Tillamook County. For genealogy research, these records fill gaps that official government files may miss.
Tillamook County Clerk Genealogy
The Tillamook County Clerk holds the core set of local records. Marriage licenses, property deeds, and lien filings date from 1853. Military discharge records and other personal documents filed with the county are also available. The clerk's office is open to the public, and staff can help you search index books.
Deed records in Tillamook County show the full chain of ownership for every parcel. Early deeds describe large tracts of timber land and dairy farms. As the county grew, parcels were split and sold. Each deed names a buyer and seller, lists the price, and describes the land by section, township, and range. For Tillamook County genealogy, these records place an ancestor on a specific piece of ground and show how long they stayed.
Under ORS Chapter 192, public records in Tillamook County must be made available upon request. The clerk may charge a small fee for copies. Certified copies cost more than plain ones, so only ask for certification when you need it for a legal matter.

Tillamook Dairy Records and Genealogy
Tillamook County is famous for its dairy industry. The Tillamook County Creamery Association, founded in 1909, became one of the best-known dairy cooperatives in the country. Its records name member farmers, list their herds, and track milk production. For genealogy, these cooperative records connect a Tillamook County ancestor to a farm and a livelihood.
Before the creamery association, smaller cooperatives and private creameries dotted the county. Their records are harder to find but worth the search. Account books list farmers who sold milk. Meeting minutes name board members and vote counts. These files show the web of connections between Tillamook County dairy families. Many of these families were related by marriage, and the cooperative records can help you trace those links.
The dairy industry also drew workers from outside the county. Cheese makers with special skills came from Switzerland and other parts of Europe. Their names appear in cooperative records, immigration files, and naturalization papers. Tillamook County genealogy for these families often requires a mix of local and federal records. The county clerk, the State Archives, and the National Archives all play a part.
Note: Tillamook County Creamery Association records may be held by the association itself, so contact them directly for access to historical files.
