Thanks so much. No, I do not have the married names for either of these daughters. I have not checked for marriages in Mountrail County, nor a cemetery book, but will do so. I also do not have the obituaries for the parents, but do know they are buried in the St. Olaf Cemetery in Tagus. (Also buried with the parents are their three sons - George Conrad, Ole and Andy). Unfortunately, I did not know my grandmother had sisters on the day I visited the cemetery, or I could have looked around to see if I found their first names there. I did not know about the Tales of Mighty Mountrail book. I will try to search it out online.
