Kalvig.Berg.Larsen.Braekken:Kolvereid/Namsos

I've had no luck finding the following family members, born in the mid 1800s in the Kolvereid/Namsos, Nord-Trondelag, Norway area: Anton Kalvig Anne Gulbransdatter Berg Kalvig Paul Gulbransen Berg Bergsvig Farm Hans Gulbransen Berg Peder Kornelius Braekken (Bracken in USA) parents to Christian Larsen Finnehoug Aside from finding a passenger list including Christian Larsen, his family, and Paul G Berg and his family, I've not been able to find any further documents for them, (except one census for Christian Larsen on DigitalArkivet) or any for the others. Does anyone have any ideas? Thank you so much!
