Civil registration of marriages began in Oregon in 1850. They were not registered in Multnomah County, until the creation of the county in 1854. For the few years before that, civil registrations of marriages occurring in the area which would become Multnomah County were recorded in the parent county, either Clackamas County (area east of the Willamette river) or Washington County (area west of the Willamette river).
Church or newspapers were the only recorders of vital records for the very earliest marriages, before civil registrations, or before 1850.
