You also have to consider that it is quite common for age to be given wrongly by the member of the family trying to answer the enumerator's questions. The five men I mentioned were possible matches for the father - not the son. None of those was expected to be a match for the 'baby' Nils. Without the date correction for the christening, it was sitll possible that the child wasn't born until shortly after the 1865 census - therefore I wanted to consider all the possible father candidates and look at the farms where they were residing. A child born in 1865 would be recorded as age 1 in the Norwegian census of 31 Dec 1865. Given the matches to both the father and mother that the original poster presented - consider again the family living on Vigen. http://digitalarkivet.uib.no/cgi-win/webcens.exe?slag=visbase&sidenr=10&filnamn=f60544&gardpostnr=129&sokefelt=skjul
