Nicolai Leonard Trane Johansen og hustru

Is there anyone that can help me find some records of Leonard Leonard Trane Johansen and his wife Marie Karoline (Caroline) Larsen? Nikolai emigrated to america the 24th of April 1909 and he came back to Norway in 1924 I think. His homeplace before emigrating was Ibbestad in Nordland. It would also be nice to know if he had any children in america. Marie Karoline Larsen is from Finnmark or Troms, I belive she is from Alta. I have been told that her fathers name was Simon Larsen. Nikolai and Marie had a child (my grandfather) in 1927 (26. nov), there were other siblings but I do not have the information. If there are anyone with some information I would appreciate to hear about it.
