Anders and Anna Seim

Hi all! I was wondering if I could get some help finding a passenger list for this couple, married on 29 April 1855 in Lærdal, Sogn og Fjordane. I am clear on the lineage of both already, but I can’t find when they came over. They settled and died in Crawford County, Wisconsin. Originally I had the wife of Anders Torsteinsen Seim as a Anna Jensdatter Seim, but I was incorrect. His wife is Anna Svendsdatter Seim, as is seen in the marriage record. Anything helps, thanks again!
