Ship "Hero " 23. 5 .1882

My data listing "Berntine (20) & Konstanse Dahl ( 17) " my GGM emigrating to America on 23. 5. 1882 has brought no additional info. Have checked Passenger lists of connecting lines, from Trondheim-Christiansund-Aalesund-Hull. What should I check out now? My info came from Norwegian Emigration Center . their brothers came in 1874 and I was able to find them on connecting ship S.S. City of Chester, embarkation Liverpool. Date of arrival June 15, 1874 Any help would be appreciated.
