Needing help/ideas

My name is Tom Pluff (new to site). I am trying to find more information on two of my ancestors and the ships they may have come in on. I have not been able to find much to work with and I am hoping for ideas. Would anyone have information on the following. Andreas Larsen Haakenstad b.10/21/1828 Ringsaker, Hedmark, Norway d. 7/29/1917 Dane, Wisconsin Arrived U.S. 1887 Andreas Anderson b. 7/18/1820 Oppland, Norway d.Jan. 1860 Christiana, Dane, Wisconsin. Would anyone have any ideas or information on them or where I may find information.
