The King County Archives maintains many records that can be useful to family history researchers. This includes many types of records that are not traditionally considered genealogical in nature, but which can provide information about the lives of your ancestors in King County. If you ancestor may have interacted with King County government, we may have a record of that connection. Some may be accessible by name; others only by a date or a geographic location (section-township-range).

Our staff can answer genealogy-related questions and provide access to records that may hold genealogical significance. We can help you most effectively if you can provide us with information that directly relates to your research topic: names, dates, locations, or anything you know about how your ancestor(s) may have interacted with King County officials.

We also make records available to onsite researchers. Please make an appointment at least one business day in advance of your visit so that we can be sure to have records ready for you. You may contract with independent researchers (external link) in the Puget Sound area if you are unable to visit our facility or if you require extensive research assistance.
