The "Skagit County Washington Index to Funeral Home Records 1908-1994" published by Skagit Valley Genealogical Society, lists Johanna Widlon d. 1924 age 85 yrs. The Cemetery is not listed but Evans Funeral Home is listed as having made the arrangements. Of course they are no longer around but if you would like to persue further information, you might consider contacting Kern Funeral Home. I believe they have the longest history in this area.

There was no listing for Swan so I would guess that he died prior to 1908.
