Interesting news. Thank you, Stefan.
Definitely a nice touch for Prince Henrik. Something akin to the Mountbatten-Windsor in the UK.
So, it will be
Crown Prince Frederik of Denmark, Count of Monpezat;
Crown Princess Mary of Denmark, Countess of Monpezat;
Prince Christian of Denmark, Count of Montpezat;
Princess Isabella of Denmark, Countess of Monpezat;
Prince Joachim of Denmark, Count of Montpezat;
[Princess Marie of Denmark, Countess of Monpezat]
Prince Nikolai of Denmark, Count of Monpezat
Prince Felix of Denmark, Count of Monpezat.
It will be hereditary for any child born within a legal marriage.
As female descendants get the Danish title Komtesse on their own, (Prinsesse Isabella til Danmark, Komtesse af Monpezat) whereas the spouses get grevinde by way of their husband's title (EG. Prinsesse Marie af Danmark, grevinde af Monpezat)- is there such a distrinction in English?
I'm a bit uncertain as to whether it would be tied-in with the title Prince of Denmark, and whether or not the "legal marriage" would need to have the permission of the monarch for the title to continue, or if it could be a supplement to the Counts of Rosenborg...
