There is no law that prevents this, exactly. I think this is what happens to all ordinary people. But I highly doubt that a marriage between first cousins, for example, would be accepted.
Elisabeth possibly as her father ,grandfather and great uncle all married the members of the European nobility
Indeed look at the rocky marriage of Albert and Paola ,but thankfully they have over come it all and are now a united couple.
Indeed. The only marriage to a commoner n the belgian RF is the one of Laurent and Claire (not counting the half-siblings of King Albert II. and King Baudouin).
A marriage between first cousins would most likely be frowned upon socially in Sweden but it's perfectly legal.
One of the daughters of Fürst Erich and Fürstin Mathilde of Waldburg-Zeil would be good matches and not be so much younger. And as his mother of from an not even mediatized Family they would be aproved as equally.
Is he still in a relationship with the Italian girl?
Not sure, but he was a guest (he and his sister Gabriela) at Margherita's brother Guy wedding to Princess Xenia of Croy last month
They would certainly be, also age-wise.
Also
But then she isn't royal or noble herself.
I included her as she's a granddaughter of the Infanta Beatriz of Spain and the great grand daughter of Alfonso XIII.
King Felipe, his mother and sisters all still attends the some of the weddings of the nobility ,perhaps Leonor might follow her father's example?
Sibilla Weiller is/was as aristocratic as can be without having a title.
Her mother is aristocratic so she is descending from aristocrats through her. But we are discussing royal/royal marriages here and from that she is far away, despite being the great-granddaughter of a spanish King.
I don’t know her mother was an Italian princess or just Donna in the Italian nobility but I think sibilla’s lineage could be compared to that of Sarah, Duchess of York as both of them are descendants of the nobility in The female line through their mother’s but aren’t titled themselves, although bounce points for Sibilla for being a great granddaughter of a king!
Sibilla's mother is (she's still alive, as far as I know) Donna Olimpia Torlonia di Civitella-Cesi
Sometimes I saw people referring to her mother as Princess Olimpia Torlonia and sometimes as just Donna Olimpia, similar to Paula of Belgium.
The correct title is Donna, both for Olimpia and Paola (not Paula). Typically, in Italian princely families only the wife of the Prince (holder of the title) was a Princess, while a daughter was "Donna". Another example that comes to mind is the late Marella Agnelli (Gianni Agnelli's wife; she also happened to be an aunt to Lili Rosboch, Prince Amedeo of Belgium's wife), who was the daughter of Prince Filippo Caracciolo ( 8th Prince of Castagneto), and she was known prior to her marriage as Donna Marella Caracciolo di Castagneto
