Because the elder girls had grown, it will likely never be possible to accurately determine which remains belong to which specific daughter. DNA has confirmed that four females are genetically related siblings to each other and are the children of the adult parents Nicholas and Alexandra. The one male child is also an exact match all around. So, frankly in the end, does it matter to ever know which skull belongs to which daughter? To me, it does not. They are identified, known, and buried and will hopefully soon be joined by their brother and sister.
