I am looking for information about my great-grandparents.

My great-grandfather, John A Julesberg, immigrated from Norway approx 1880 to Wisconsin. My great-grandmother Mathe (Martei/Mattie) Julesberg immigrated from Norway approx. 1890 to Wisconsin. I believe they were married in La Crosse approx. 1893 and had 4 children in La Crosse (George "Conrad", Ella O, Anna Louisa, and Mabel Josephine - my grandmother). They moved to Tagus, North Dakota, between 1902 and 1905 and had 2 more children (Ole A and Andy).

I cannot find any information on my great-grandparents' family in La Crosse. Can anyone help me? Thank you
