Finstad Christiansen imm. to WI

The line I am looking for is from Stange, Hedmark, Norway... they immigrated to Hale Township, Trempealeau County, Wisconsin. I have all census info and am trying to find how they traveled to the US... Boat/Ports/US or Canada... The name would be Peder C Finstad is the name he used in the US... however in Norway he was a Christiansen... I have this from the digital archive but am not sure if it means he left Norway on the date 5.5.1884 - http://www.arkivverket.no/URN:kb_read?idx_kildeid=3569&u... He is located in 1884 line 4 of the bottom right side of page 281.... I think his brother came to the US in 1882 through Canada from what I have found but nothing relating to him... I know he was married in 1885 in Hale Township in Wisconsin Some extra info Peder C Christiansen (Finstad) it is often mispelled b. Jan. 19 1855 Stange Parish Norway d. Jan. 16 1896 Father - Christian T(h)rondsen (this may be spelled wrong) Mother - Berte Pedersdatter Spouse - Johanne Torklesen (I have different spellings) Here's the telling for him in Norway - http://www.digitalarkivet.no/cgi-win/webcens.exe?slag=visbas...
