Pedersen 1866-1867

I'm looking for this family: Pedersen, Augusta (age 44 in 1880) - mother, born in Norway Pedersen, Pauline (born in 1861?) daughter, born in Norway Pedersen, Bennett/Bernhardt (age 16 or 18 in 1880) son, born in Norway Pedersen, Anna (age 13 in 1880) daughter, born in Norway The mother is a widow in 1880. I've been told them came from Bergen around 1866 or 1867. I'm not sure where they lived in Norway though. I've tried searching on my own, but I'm not having much luck. I'm wondering if someone here can help me. Thanks!
