passenger list

Help! this is my first time. I am looking for my husbands family they lived in Kopparbergs Sweden. They boarded ship in 1902 with 5 children that landed in Boston Mass. His grandfathers name was Isaks Erik Eriksson wifes name Brita Adamsson. He wrote that he was given a solders name and that was Krans and that is the name he kept and gave his children. If anyone can lead me in the right direction I would really appreciate it.
