I don't know of any Magnus Blixhavn in our family. My Grandfather was the only son in his family. Thor Mattias (my Grandfather) grew up in Sharon , North Dakota. He did grow up living with relatives but I don't know what their name was. Are there any other names in Magnus' family that you know of, maybe some of them would make a connection to our family because I never heard of another Blixhavn family in that area.
