Helge Olsen Hellerud and Ingeborg Thoresdatter

Helge Olsen Hellerud was born 28 Oct 1820, Eggedal Parish, Buskerud, Norway. He married Ingeborg Thoresdatter Tollefsrudie, born 10 Mar 1830, Flaa Parish, on 9 Jan 1851, in the Flaa Church, Flaa Parish, Buskerud. They had one son, Ole Hellerud, born 17 Jan 1851, before they left for America in about 1852. Family information is that Helge, Ingeborg and son Ole, possibly with three brothers of Helge (these names are unknown to me), left for America between 1852 and 1854, route: possibly Drammen, Norway to Quebec, Canada. From Quebec, they went to Hamilton Co, Wisconsin. I know they were in Hamilton Co, Wisconsin by 17 Mar 1855, because their son, Even, was born there then. Therefore, they must have traveled to America between 17 Jan 1851 and 17 Mar 1855. I am looking for the ships passenger list for this family.
