Trying to find information on Mina Kostad

I am trying to find where the first wife of my great grandfather Hans Kostad came from in Norway. I do know that his wife's name was Mina Jacobson and she was born April 25, 1891. I would like to try to find out who her parents were and where she came from in Norway. Hans came to America in the 1890s and went back to Norway in our around 1914. Mina and he were married in Lignite, ND in about 1916. Any help would be greatly appreciated.
