Had they decided to include Harald's sisters in the line of succession and place them and their children ahead of Harald, the line of succession would look very different....
(this thought came up after reading this news
) - of course, I know it's not realistic... Among other reasons because the chances are very slim that they would have been able to marry the partners they ended up marrying.
In this hypothetical situation, we would have: KING HAAKON & QUEEN MARTHA

1. Crown prince Olav (with Crown princess Ingrid)

Went with surnames of the fathers for the non-male line descendants following the way this was handled for ML and Ari Behn (even though in reality Raghnild's and Astrid's descendants use different (combined) surnames).
