Johannes Borreson

My great-grandfather Johannes Borreson was born 20 Jul 1840 in Toten, Oppland, Norway. His parents and siblings are included in the 1865 census, here: http://digitalarkivet.uib.no/cgi-win/webcens.exe?slag=visbase&sidenr=7&filnamn=f60529&gardpostnr=306&personpostnr=1863&merk=1863#ovre but I can't seem to find Johannes. He immigrated to America in 1868 and I have found him in the 1870 Wisconsin census. Thank you for your help.
