First instead of the email address given by Shotgun, I'd suggest the direct link via:
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" .Depending on the amount of requests, it could take up to a couple of weeks.
But, let me forwarn, obits were not that common back in that time period.Obits were usually written by reporters for the rich, famous or imfamous.A death notice was written about the common folk, but usually just an advertisement for the funeral home.
I did do some research on the family, if you can't get an obit, it might give you some leads:
