Oregon Records Details and Resources

By Family Tree Editors Premium


Oregon’s boom years were tracked by a succession of territorial censuses beginning in 1842 and repeated almost annually until statehood; the Family History Library (FHL) has indexes to the surviving schedules. These and subsequent state censuses in 1865, 1875 and 1885, typically name only heads of households. State censuses in 1895 and 1905 list all family members. The first federal census to include Oregon Territory was in 1850; it was enumerated as a state beginning in 1860.

Oregon didn’t begin statewide birth and death registration until 1903, marriages in 1906 and divorces in 1925. Many of these records, along with earlier local vital records, are at the state archives. The online Oregon Historical Records Index totals more than half a million entries, including Portland births (1881-1902) and deaths (1881-1917). The archives also has some early probate records, though these largely remain at county courthouses.

Land records can also provide clues to ancestors who joined the rush to Oregon. Territorial land records have been indexed and are kept in the state archives. Look for Donation Land Claims, which document those who arrived by 1855 and contain records rich in details about the settler family. Federal land records are available on microfilm from the FHL; post-1908 records are in the Bureau of Land Management’s database at

Don’t forget that Oregon had joined the Union by the time of the Civil War, so its military records go back to that conflict. The FHL has microfilms of service and burial records of Oregon soldiers in the Civil War.

The biggest challenge for Oregon researchers, according to Connie Lenzen, a member of the Genealogical Forum of Oregon, is that many of the records you’ll seek are still in courthouses, archives and libraries. Generally, she warns, they are not published or online. But the Oregon Death Index, included in the subscription service, and the aforementioned Oregon State Archives’ Historical Records Index, can help you get started long-distance.

Because so many Oregon records are located at the county level, Lenzensays it’s crucial to first locate your ancestors in censuses so you know where they lived. Records in county courthouses may be difficult to access from a distance, she adds: “Most offices are short-staffed. The day-to-day business of running a county government takes precedence over answering queries by mail.”

Ferne Kellow, president of the Oregon Genealogical Society, adds that many records may not be filed where you might expect. For example, Kellow found the pioneer cemetery records for a Josephine County-owned cemetery in the county’s Parks and Recreation Department. The Oregon Historical County Records Guide can help you figure out what’s where.

The number-one research repository, according to Lenzen, is the Oregon State Archives in Salem. You may not even have to leave home to tap the archives’ holdings: The FHL has microfilmed many records at the Oregon State Archives and other state repositories

For published resources, she adds, the holdings of the Genealogical Forum of Oregon (GFO) are among the best in the state. The GFO will look up materials in its library for a nominal fee. See the research policy at The largest collection of Oregon historical materials belongs to the Oregon Historical Society Library in Portland, which holds books, photographs, maps and original documents. You can search its catalog of book and serial holdings online at
