Petter Jentoft Harwick

Hello all Looking to find any information about my great grandfather Peter Jentoft Harwick. I know his birthday is April 28 1882 born in Narvik, Norway. I believe he came to the US around 1900-1907. In the US lived in New York City. I sent away to NYC for his marriage cert. and death cert. to see if it has any other info that would help me locate his norway origins. I found his birth date and place of birth from a world war II draft registration card.
