I myself have not made any research, I am only referring what other genealogists write on this subject. Klingaasen sounds like the name of a village, maybe the home-site of Carl. But there is no such village. Someone, probably Leonard Bygdén, connected this Carl Klingaasen with Karl Laurensson in Kluxåsen. There is also an old saying among the early Blixes that their ancestor (Mogens´father?) was a danish gentryman, so there is no proof that Mogens' father is Karl Laurensson.
