Looking For Knut Hansen /Seattle-Alaska 1958?

Knut Hansen (approximate age 65-75) married Susan Eva Kirkpatrick in King Co. Washington (Seattle) December 1957. Moved to Alaska where a daughter, Susan, was born 12/28/58 and myself, Teresa, was born 02/20/61. I have been told that Knut and his cousin? Erling Petserson came to Seattle from Borgen? Norway and that he sailed on the "Explorer" (Merchant Marine?) out of Seward, Alaska. I have not seen Knut since around 1974 and would very much like to find him and/or any others who may know about my family medical history. I seriously need medical history from this segment of my separated family. I am hoping, as well, to close the gap with this gentleman who was/is my birth father. Thanks in advance for any assistance you may offer.
