Obituaries for this period of time were still not as common as today. BUT, you can try: The Washington State Library has a free research service, the ask-a-librarian program, where they will look for information in the archives, in this case the newspaper microfilm for an event, such as an obituary. They will look up to an hour and send you the results. Contact them at: http://www.secstate.wa.gov/library/ask.aspx .
