There is an Earl married to an Amanda/Vanda Vanderwerker in Coos they operators on a stock ranch on the 1950 census.
The only reason I ran across this is that my grandmother Mary Elizabeth Burk (johnston) married a E Harold Vanderwerker. I actually have a bank loan card for him in Coos from 1951. I was looking for additional information on my grandmothers life here in Oregon and remembered this.
and then saw your post.
