Hanson in Alaska

I am looking for a family who immigrated to Ketchikan, Alaska from Norway. Here is what I know: The family owned a dry cleaner at 105 Stedman Street in Ketchikan. The father's initials (listed in phone book) are CH Hanson. They had at least one daughter who had the married name of Hoffman/Hoffmann. This daughter had a son in 1957 who was adopted at birth. I'd like to know the full names of any members in this family and where in Norway they came from. Any help is appreciated!
