Unknown Parents Parents

What about this profile: Margrethe Olavsdotter, should she be disconnected from her parents aswell? It looks like only "evidence" for this relationship was the claim that Audun i Borg was related to Inga i Varteig in some way, and before Inga was disconnected from her parents, Inga was listed as Auduns sister-in-law. I guess this means that Auduns wife also should be disconnected from her parents, but was she a sister of Inga?
