Puzzle needs solving

I am trying to locate a passenger list and birth record for the following two family members.... Caroline Hendricksen b.1836 Norway (per 1860, 1870, 1880 census and bur. record) also listed as Karen on two of her children's birth records her father Torsten Hendricksen (also seen as Tuston and Tosten Hendriksen) b.1783 Norway (per 1870 scensus) or b.1790 Norway (per burial record in Illinois) 1855 state census lists 8 children in household 1865 state census lists only 1 child youngest son Gunther Tobias Hendricksen born in Illinois in 1850 -his mother was Inga (Gunderson?) but may be a 2nd wife. I have located a Tosten Hendricsen that was born in 1783 on the 1801 Buskerud census, but need to confirm that he is the correct person. This Tosten m.1811 Anne Kirstine Hansdatter at Buskerud. Only other identified child is Henrick Henricksen b.1831 Norway (wife Karine) I believe they immigrated c1842 but have not been able to locate them using the search engines. Any help would be greatly appreciated !! Thank you.
