About the Oregon Historical Records Index
The State Archives has a number of county-level marriage records in its holdings; however, it is not a comprehensive, state-wide set of records. Whether we have a given marriage record depends on the county and date of the marriage. Often these records remain in the county's custody (for marriage records that don't appear on this index, see the Oregon Historical County Records Guide for the county in which you're interested to determine whether the record is in our holdings or in the county offices).
It is also important to note that the majority of marriage records in our holdings consist of either the recorded marriage record or a marriage certificate. In fewer cases the license application materials or marriage returns (which typically include more information) appear with those records.
