The duke of Parma did the same thing. He praised his aunt's dedication to the Carlist cause 'just like my father Carlos Hugo and my aunts Maria Theresa and Maria de las Nieves'.
He also drew attention to his aunts work in Laos, Biafra etc. She was apparently also a pilot and as a volunteer for the order of Malta she flew helicopters with aid.
The princess lived for years in Paris with her two other unmarried sisters. I am not sure why the crazy brother is sending out this comuniqué AFAIK he lives estranged from the rest of his direct family except for his elder sister.
It is a first step that Sixte Henri de Bourbon de Parme mentioned his sister Marie Cécile at all. Both he and his sister Marie Françoise, douairière de Lobkowicz, acted stony silent when Marie Thérèse passed away, last year.
Maybe Sixte realized his world at Lignières is incrrasingly becoming smaller. He seems to have a "political secretariat" which posts on Facebook, but only the one ultra-catholic thing after the other. He stands for a total different Carlism, longing for the era in which the Bourbons, the aristocracy and the Church ruled Spain and France.
Democracy, citizen participation, woke culture: it will feel like pure craziness for Sixte Henri and Marie Françoise.

Seeing that Prince Sixte Henri is quite close to his eldest sister Princess Marie-Françoise, douairière de Lobkowicz, I think the domain and the château de Lignières will go to his nephew Charles-Henri, Prince de Lobkowicz.
Via his mother Marie-Françoise he already is the
proprietaire of the Château de Nouveau-Bostz, the Château de Vieux-Bostz, the Château de Fourchaud and the Manoir d'Ujezd. With the Château de Lignières it would make him a single unmarried man owning four castles while his cousin, the Duke of Parma, was left with none.
By the way: the money lies not in these money-exhausting castles... It lies with the lands around which brings in annual rents by farmers and tennants.
Besides this Marie-Françoise also inherited lands in Ujezd (Czech Republic), the ancestral lands of the Lobkowicz princes. The Lobkowicz Palace there is now the German Embassy in Prague.
