My point was that the fathers don’t need to be made counts for the children to be counts or countesses. Claus-Casimir and his sisters were made count and countesses in their own right; they didn’t inherit the title from their father, who is not a count. himself.
And, again, as I said, under the Law on Nobility, any member of the Royal House, including Ariane’s and Alexia’s children as long as Willem-Alexander is king, can be ennobled by royal decree.
It is not possible anymore to ennoble the children of Countess Eloïse and Countess Eleonore because their consanguity to the Sovereign is more than two degrees:
0 - King Willem-Alexander
1 - Princess Beatrix
2 - Prince Constantijn
-----------------------------
3 - the children of Prince Constantijn
It is indeed possible to ennoble the children of Princess Alexia and Princess Ariane as long as their father is King:
0 - King Willem-Alexander
1 - Princess Alexia
1 - Princess Ariane
2 - the children of Princess Alexia
2 - the children of Princess Ariane
Under Queen Catharina-Amalia, her children's sisters will become too remote for the membership of the Royal House, she can not ennoble them anymore.
0 - Queen Catharina-Amalia
1 - Prince Willem-Alexander
2 - Princess Alexia
2 - Princess Ariane
-------------------------
3 - the children of Princess Alexia
3 - the children of Princess Ariane
