Engebret ENGEBRETSEN SANNER (or SANDER?)

Could someone help me, please? I am working my way through the passenger list for 1872 Høvding (Oslo to Napier, New Zealand). I have Engebret ENGEBRETSEN SANNER on the emigrants list as follows: http://digitalarkivet.uib.no/cgi-win/webcens.exe?slag=visbase&filnamn=EMIOSLO&gardpostnr=25143&spraak=e. 25143 Oslo 400A 1872 30 Engebret ENGEBRETSEN SANNER m G Arb. - 36 S. Odalen New Zealand 1323 Norsk œ 32 Høvding I think this is the same person in the 1865 census at Sander, Strøm, Søndre Odalen, Hedmark, Norway: http://digitalarkivet.uib.no/cgi-win/webcens.exe?slag=visbase&filnamn=f60419&gardpostnr=583&personpostnr=3656&spraak=e. 3656 18 1 Engebret ENGEBRETS. Husfader Gaardbruger og Selvejer g 27 m Søndre Odalen Prgj. Does this mean that he should have been recorded as 'Engebret ENGEBRETSEN SANDER' instead of 'Engebret ENGEBRETSEN SANNER'?
