Trygve Reinulf Martinsen born 1906

He was the brother to my grandmother and I was told that he emigrated to America, but don`t know from where and when. Trygve Reinulf Martinsen was born 21 Dec 1906 in Kjelvik, Maasoy, Finnmark, Norway and his parents was Martin Bernhard Johansen [1874-1966] and Amanda Ovidia Tollefsen [1876-1948] He had one child born in Norway in 1926, and her mother was Marie Karoline Andersen Lafjord. I don`t think they emigrated with Trygve Reinulf. I have been told that he married a woman called Emmely in US, but have not her last name. Trygve Reinulf and Emmely they both died in USA, maybe New Jersey. Now I want all information about him if from his life in USA if it`s possible. I don`t know anything about it.
