Gierulfsens in Oyestad

I am looking for information on Gierulfsens in Oyestad. The specific family I am looking for are Ole b 1770, Melchior b 1769 and Hans Casper b 1777. Parents are Gierulf Olsen and Stine Hansdatter. I would especially like to confirm in some way that this Hans Casper is the same one who was in the Danish Navy in Copenhagen in 1805. I can't find a link in the Danish records so I am switching to the Norwegian ones. In the 1801 census I believe I have located Ole and Melchir (Michel) at the Nevasdal farm with several other Gierulfsens. http://digitalarkivet.no/cgi-win/WebCens.exe?slag=visbase&sidenr=9&filnamn=f1801&gardpostnr=27483&personpostnr=401406&merk=401406#ovre Hans Casper appears to have been in Klodeborg. http://digitalarkivet.uib.no/cgi-win/WebCens.exe?slag=visbase&sidenr=1&filnamn=f1801&gardpostnr=27503&personpostnr=402884&merk=402884#ovre Thanks!
