It's going to take some time, by someone with Norwegian experience, to trace the patronymics, farm names, and people. The big thing to remember is that names were not spelled then, they were spoken, so spellings did not matter! If they were written down, it was typically by a Danish cleric, who wrote them as he thought they sounded. Marie's profile is an excellent example, with 4 different spellings of Bentdalen.
The next thing to remember is that they did not have last names (with a few exceptions, like some city dwellers) until they came to America, or if they stayed in Norway, the early 1900's. Those extra names were associated with them, but were not the names they were called by. The extra names identified whose father they had, and usually where they lived. (You probably knew that already.) But we now assign last names to them from those extras.
There isn't a good standard yet for Norwegian names, so they are often handled in inconsistent ways. There have been some good attempts to standardize early Scandinavian naming, mostly very well expressed by those with a Dutch point of view or Swedish point of view, but those countries had mostly settled on fixed names by early genealogical times, and Norway did not until much later. So farm names are much more important in Norwegian naming. LNAB is a real problem here, and they did not have married names.
(Someone with more Norwegian experience than myself may correct any errors I've made.)
