The name of the mental hospital in Sedro Woolley (Skagit County) was Northern State Hospital. It, and its records, no longer exist. My father was always told that his father died in the flu epidemic of 1918 in a hospital in Seattle. His brief obituary said that he died at home in Tacoma after a short illness. Imagine my shock when I got the death certificate and it said he had died of "paralysis of the insane" after an incarceration of 8 months in this hospital! His death certificate indicates that there were extenuating documents attached to the certificate (or filed with it). I have had lengthy long-distance phone chats with both the Washington State Board of Mental Health and the Vital Records Department in Olympia and they have either found nothing or never gotten back to me. One clerk did say that Northern State was the only hospital in Sedro Wooley and sometimes when people died, a doctor from there would be the certifying offical on the death certificate and that would cause the certificate to be filed with the hospital's address, rather than the residential address of the decedent.
