Welcome Gilliam County

The Legislative Assembly created Gilliam County on February 25, 1885 from the eastern third of Wasco County. Residents argued that they were too far from the county seat in The Dalles. In 1899 a portion of southern Gilliam County was used to form Wheeler County. Gilliam County is bordered today by the Columbia River to the north, Wasco and Sherman Counties to the west, Morrow and Grant Counties to the east, and Wheeler County to the south. Gilliam County's area is now 1,223 square miles. It was named after Colonel Cornelius Gilliam who died accidentally while commanding the Oregon volunteers during the Cayuse War of 1847. For more history visit the Oregon Secretary of State's Gilliam County History page.

Keep in mind that Gilliam County was created from Morrow and Wasco Counties, so some records may be found in those counties.
