Not fathers of the married couple but it is best man for groom and wife (Forlover)

Hey, at least they got the correct grooms and brides. There are entire pages of baptisms in Hungary and Slovakia where the godparents got indexed as the parents, which means that everything except the child's given name is wrong in them -- and the Slovakia ones can't even be edited. That's the way of indexes: they have errors. Hopefully the users of the Norway Church Books index will know never to take an index as fact and will check the image themselves for the correct identifications.

But if you're feeling charitable with your time and energies, the index in question is user-editable, so you could correct the fathers' names. (You'd need to do something like "not named", I think.)
