Wasco County Clerk Genealogy Files

The Wasco County Clerk in The Dalles holds records that go back to 1854. That makes this one of the deepest county record sets in all of Oregon. Marriage files, deed books, lien records, and court filings are all stored at the clerk's office. These form the core of Wasco County genealogy research.

Wasco County was named for the Wasco Indians who lived along the Columbia River. When the county formed in 1854, it was vast. It covered most of central and eastern Oregon. Over time, other counties were carved from it. But the records from those early years stayed in Wasco County. This means that some of the oldest land and court records in the state are filed right here in The Dalles. For genealogy, this is a major asset. Your ancestor may have lived in what is now a different county, but the record of their deed or marriage could still be in Wasco County.

The clerk logs every land sale, marriage, and lien. Deed books from the 1850s and 1860s show the first wave of settlement along the Columbia River. These entries list the buyer, the seller, the price, and the tract. Under ORS Chapter 192, these records are public and open for review. You can visit the clerk's office in The Dalles or request copies by mail.

Fort Dalles Museum and Wasco Records

The Fort Dalles Museum sits on the grounds of the old military fort in The Dalles. It is one of the oldest museums in Oregon. The fort was built in the 1850s to guard the Oregon Trail and the river crossing. Soldiers, traders, and settlers all passed through here. The museum holds photos, letters, maps, and artifacts from this era. For Wasco County genealogy, these items add color and context that official records cannot match.

Military records tied to Fort Dalles can help trace ancestors who served there. The fort was active from 1850 to 1867. Muster rolls, supply records, and post returns list the names of soldiers and support staff. These records are held at the National Archives, but the Fort Dalles Museum has copies and guides that can help you find what you need. If your ancestor was posted at Fort Dalles, these records will show their name, rank, and dates of service in Wasco County.

The museum also documents the Oregon Trail crossing at The Dalles. This was a key point on the trail. Wagons could take the Barlow Road or float down the river from here.

Columbia River Trade Records

The Columbia River was the main road in and out of Wasco County for decades. Steamboats carried goods, people, and mail up and down the river. The Dalles was a major port. Warehouses, docks, and freight offices lined the riverfront. The people who ran these operations left records that are useful for genealogy work.

Shipping logs, warehouse receipts, and freight bills list names and dates. Some of these records ended up in Wasco County court files when disputes arose over lost or damaged goods. Circuit Court case files from the 1860s through the 1900s hold a wealth of detail about river trade and the people involved. These files are at the Oregon State Archives in Salem. They can reveal an ancestor's role in the commerce that built The Dalles and Wasco County.

The railroad arrived in the 1880s. It changed how goods moved and brought new people to Wasco County. Railroad land grants are a type of deed record. They show large tracts given to rail companies, which then sold smaller parcels to settlers. These sales appear in the Wasco County deed books. If your ancestor bought land from a railroad company, the deed will show their name, the date, and the parcel location. Under ORS 192, these deed records are open to the public.

Wasco County Land Genealogy

Donation Land Claims from the 1850s are some of the oldest records tied to Wasco County. These claims were filed by settlers who arrived before the land was surveyed.

Together, these federal records and the county deed books create a full picture of land ownership in Wasco County that spans more than a century.

Water rights are critical in this dry part of Oregon. Farmers and ranchers filed for rights to draw from creeks and the Deschutes River.
