Researching Your Family Through Land Records

The King County Archives maintains several types of historical property records that can be useful to family history researchers. Generally, these records document real estate that was owned, sold or purchased by an individual. This information can be especially helpful in documenting the times and places that your ancestors may have lived within King County.

The best way to start researching your family's real estate ownership is by locating deeds (instrument by which real estate is bought, sold or transferred) and other recorded documents.

1) To locate a deed or other recording, you must have a volume and page number that can be found by using name indexes:

Name indexing to recordings is provided through the General Recordings Index. This index (also known as grantor-grantee index and direct-inverted index) tracks instruments related to ownership of and access to real property and other recordings. Recordings indexed include deeds, mortgages, conditional sales contracts, chattel mortgages, lis pendens, liens and easements. Direct indices index each instrument by the name of the grantor (party selling or conveying). Inverted indices index instruments by the name of the grantee (party buying or receiving). Within each volume/reel, entries are alphabetical by the first three letters of the last name and then chronological. Index entries include the date of the record, the names of eachparty, the type of record, the volume and page of the recording and remarks.

Indexes from 1853 to 1975 are on microfilm and can be researched in person at:

King County Archives in Seattle (1853-1975)
Puget Sound [state] Regional Archives (external link) in Bellevue (1853-1971)

Index from 1976 to present is a computer database that is available for searching online on the King County Recorder's Office website.

2) Once you have located a recording type and volume and page number, you can access a copy of the recording at the King County Archives.

The King County Archives also maintains a variety of other records (in addition to deeds) that can be used to track a family's real estate ownership:

  • Donation Land Claims Index and Maps (1861-1882)
    Under the Oregon Donation Land Claims Act of 1850, Congress allowed 320 acres of land in Western territories to be claimed by a single person and 640 acres by a married couple. The claimants received final title to their land when they had lived on it for four years and made certain improvements, or when they purchased their land in lieu of fulfilling residency requirements. Records include a name index to Donation Land Claim owners, as well as legal descriptions and maps of land claims.
  • Land Office Correspondence (1879-1887)
    This series includes correspondence between the Clerk of the Territorial District Court in Seattle and the U.S. Land Office in Olympia. Usually, the correspondence pertains to incomplete homestead applications. Most of these applicants were instructed to provide signatures, proofs of naturalization, fees or other application requirements. Some letters from homesteaders to the Land Office are included. The correspondence generally includes information such as the names of the land owners, the date their land was settled or a legal description of the property. Other valuable information is sometimes included including a description of the family (spouse and number of children), occupation(s) of land owners, land improvements and/or building descriptions. Although this series dates from 1879, most of the correspondence is from 1884-1887.
