In the article 20
Are members of the sovereign family , after the status; the autors of the prince and his spouse and all the persons who are in the line of sucession after the article 10 of the constitution, and their spouses or husbands a part the parents after the third degree
Tazmin and Alexander but also Raphael and Camille don't belong officially to the sovereign family, their parents are not married and to be in the line of sucession , the persons must be legitimat.
It is the officially sovereign but in privat Camille and Raphael are the members of the family as in other all family, there are no difference as also Jazmin who attended the lunch of the christening of Jacques and Gabriella
the sovvereign family is untill the third degree , I believe that the De Massy are no more in the official sovereign family.
