Between 1855 and 1910 the U. S. government kept records of all federal land transactions in Washington State. These records can contain genealogically significant information. Microfilm copies of these records are kept at the NARA Pacific Alaska Region facility in Seattle, Washington.
The records include land transactions under various laws and acts, including: donation land, homesteads, timber and stone, timber culture, desert land, mining, and some cash sales. The records also include tract books (township, range, section, and fraction of section) with lists of owners.
There are records of homestead entries and final certificates, desert land declarations and entries, timber culture entries, abstracts of land sold, and patents delivered.
