Corvallis History and Records
Corvallis was incorporated in 1857. It briefly served as the capital of Oregon Territory in 1855. The city sits at the meeting point of the Willamette and Marys rivers. Early settlers farmed the valley floor and cut timber from the hills to the west. The name comes from the Latin phrase for "heart of the valley." That name fits. Corvallis sits near the center of the Willamette Valley.
The founding of the state agricultural college in 1868 changed everything. That school became Oregon State University. It drew students, faculty, and staff from across the state and beyond. Many of these people put down roots in Corvallis. Their families grew here. For genealogy, this means Corvallis records hold names from a wide range of backgrounds. University ties can help you trace families that might be hard to find through local records alone.
Agriculture and timber were the other pillars of the Corvallis economy. Farm records, land grants, and timber sale documents are all part of the genealogy landscape here. Benton County was formed in 1847, so county records reach back nearly to the start of American settlement in the area.
Note: Corvallis served as the Oregon territorial capital for only a brief time in 1855, but records from that period are held at the Oregon State Archives.
