It is also most likeley that the future children of Prince Sverre Magnus will not have any titles. That leaves the question as to what surname they will have.

- Glücksburg - very un-Norwegian
- Lyksborg - sound a bit strange and unfamiliar
- Haraldsen, Håkonsen or Magnusen - perhaps, but very common surnames
- Skaugum - perhaps. "Harald Skaugum" or "Sonja Skaugum" sounds a bit strange to me, but we'll probably get used to it
