You must have missed all the tabloids calling for Beatrice and Eugenie to voluntarily relinquish their HRHs or to have Charles strip them away when he is King. After all, Anne "refused" titles for Peter and Zara and so did Edward and Sophie for their kids so therefore why do "those Yorks" still have them?
Well, as we know, Anne did not refuse titles for her children being children of the matrilineal line. Just as both Beatrice and Eugenies children will also be commoners.
The problem with that is they've explicitly stated she'll be Princess Consort when the time comes back when they got married. And I am supportive of Camilla being Queen Consort, but just pointing out that they've kind of backed themselves into a corner here.
On the advice of little grey men from both within the palace and the government. However, changing her title requires and act of parliament and they are a little busy doing other things it seems. Then there's that whole Commonwealth thing . . .
The decision on the Wessex children was based on a premise that no longer exists i.e. that Edward and Sophie would pursue a life in private business and not become full-time royals. So too would Edward become the Duke of Edinburgh after the passing of his father and would thus be on a level with Andrew, Duke of York.
However, unlike the Netherlands, the media were of no mind to allow Edward and Sophie to be "private citizens" and with their active intervention, they torpedoed any chance of them pursuing their careers. They were the children of the Monarch and were shirking their Duty! Reluctantly they were forced to abandon their dreams.
However, things changed and suddenly Edward and Sophie were both required to become full-time royals, a totally unforeseen and unplanned situation. E & S became HM's go to couple for overseas royal weddings and birthdays and funerals among other things. The way the DM et al harass Beatrice and Eugenie show the media still has a taste for royalty and, as with Catherine Middleton, made any job they had very difficult.
The notion that Princess Charlotte's husband should be titled (Prince Charlotte?) would find a very strong pushback if the aristocracy were still locked into male primogeniture. It would open a whole other can of worms.
What I am saying is that we have no idea what the situation will be when H & M have children. They may still be the Queen's great-grandchildren or, they may be the King's grandchildren and, if indeed Charles was King, I believe he would want all his grandchildren to hold the same title as his own children did.
As to the requirements of the Monarchy? In the post-Brexit UK, the government may want them to step up their "soft diplomacy", hosting more State Visits and doing charm offensives all over the Commonwealth.
As I said, we none of us have a crystal ball and if this future is not the one HM saw as a young mother, there is nothing to say that the same would not hold true for the Sussexes, or even the Cambridge's. Therefore, hasty decisions should not be made and any idea of stripping the York girls of their titles is self-defeating as their titles end with them.
