They aren´t connected in family tree. Mary only recognizes Glarn and Kitty as parents, Notzo, Zo, Hamm and Annie as grandparents, Vidcund as brother, Johnny and Jill as niece and nephew and Jenny recognizes her as sister. This also explains why is she created separately from other Grunt ancestors. And Pascal and Lazlo might be replacement for her because they are last Sims added to Strangetown.
