Series records ownership of county lands obtained from the federal government. Series includes records of land grants administered under federal programs such as donation land claims and homesteads. Donation land claims are the most common type of federal land grant in Oregon that is documented in this inventory project. Donation land claims resulted from an act of the 1850 Congress under which citizens of the United States, or those who filed a declaration of intention prior to December 1, 1850 and had resided upon or cultivated the land for four consecutive years, were granted a specified amount of acreage in the Oregon Territory. Donation land claims were unique in that acreage granted to married couples was divided evenly. Half of the acreage was placed in the husband's name while the other half was placed in the wife's name. Records include plats, indexes, and survey notes. Information includes township, range, and section numbers, names of donation land claim holders and claim numbers, claim dates, acreage, and descriptions of surveys.

Under the Homestead Act of 1862, settlers were given 160 acres of land in the public domain if they built a home on the land, resided there for five years, and cultivated the land. A complete homestead entry file includes such documents as the homestead application, homestead proof, and final certificate authorizing the claimant to obtain a land patent.

1859-[ongoing]

Series documents the examination, commitment, and release of mentally ill persons to and from the state's mental institutions. Series contains statements of complaint and commitment recorded by the county clerk or recorder and includes petitions to have an individual committed; physicians certification that an individual is insane; delivery warrants authorizing a county official (usually the sheriff) to take the individual to the state hospital; patient discharges; paroles or transfers; indexes; and correspondence. Information includes patient and family names, date committed, reason, physical description, and a brief family history. This series may also be known as the Insane Record, Mental Illness Record, and Mentally Ill and Feeble Minded Record. By 1968, in most counties, the commitment of the mentally ill or deficient had become the responsibility of the circuit court. Access to these records may be restricted for 75 years by Oregon Revised Statute 192.496.

Records indicate that the circuit court assumed sole responsibility for mental cases from the county court in 1919. Mental Commitment Case Files have been indexed on the Oregon Judicial Information Network (OJIN) since 1988.

This network functionally replaced probate dockets and journals previously maintained by the courts. The transition to full use of OJIN by all circuit courts in Oregon took approximately two years. Contact the trial court administrator for access to OJIN. Portions of these records may be restricted.
