Hi, You can request a copy of an obituary from a volunteer at Random Acts Genealogical Kindness. Go to www.raogk.org, read guidelines, choose Washington, choose King Co. and choose one volunter.
OR Washington State Library, www.secstate.wa.gov/library/ask.aspx . They will search the newspaper microfilm for up to 60 minutes at no charge and reply with what they do or don't find. Takes about two weeks. Successful Searching!
