Please review NARA’s publications M1541, “Naturalization Records of the U.S. District Court for the Eastern District of Washington, 1890-1972,” M1542, “Naturalization Records of the U.S. District Court for the Western District of Washington, 1890-1957,” and M1543, “Naturalization Records of the Superior Courts for King, Pierce, Thurston, and Snohomish Counties, Washington, 1850-1974,” for information about these records. PDF versions are available from the NARA website. Please also, consider carefully the information on the NARA web page about naturalization records. Some records in this group may not exist due to destruction or they may simply be missing. Additionally, the earlier records may not be indexed at all. I will make all reasonable efforts to retrieve what I can from the indexed records that are here.
