I am looking for my great grandfather and his family in the US.

Emil Sorensen was born 1906 in Minnesota. Died 1972 in Alaska.

Lived some periods in Norway, where my grandfather, Per Tufthaug (born: Sorensen) was born outside of marriage.

He married back in the US two times, I think, and lived most of his life in Dillingham or Anchourage, Alaska.

Our family is from Hadsel, Norway. My grandfather passed away far too early and it would mean a lot for my father if I was able to find something about his fathers family.

Any help is deeply appreciated!
