Umatilla County History and Genealogy

Umatilla County formed in 1862. It took its name from the Umatilla River, which flows through the heart of the county. Pendleton became the county seat and grew into the largest city in the area. The Oregon Trail passed through this land, and many early settlers stayed after the long journey west.

Wheat farming and cattle ranching drove the county's growth. The rich soil along the river valleys grew hard wheat that fetched good prices at market. Ranchers ran cattle and sheep on the open range in the hills. These two industries created a thick web of land records, brand registrations, and business filings. For Umatilla County genealogy, these documents show where an ancestor lived, what they owned, and how they earned a living.

The Cayuse, Umatilla, and Walla Walla tribes have lived in this region since long before white settlement. Their history is woven into the fabric of the county. Treaty records, reservation documents, and tribal enrollment lists are all part of the broader Umatilla County record set. Researchers with tribal ancestry may find these sources essential for tracing family lines that predate the county's formation.

Note: Tribal records may have separate access rules, so contact the Confederated Tribes of the Umatilla Indian Reservation directly for guidance.

You can sign up at the PRAS registration page or call 541-278-6236 for help. While PRAS is aimed at current property owners, genealogy researchers can use it to track changes on land that has been in a family for generations.

Deed records in Umatilla County show the full chain of ownership for every parcel. Ranch land and wheat fields changed hands as families grew, shrank, or moved on. Each deed names a buyer and seller, states a price, and describes the land. Livestock brand records add another layer. Brands were registered with the county to prevent theft. These registrations name the brand owner and describe the mark. For Umatilla County genealogy, brand records can confirm that an ancestor ran cattle or sheep in the area.
