|The royal family before Christina's birth.|
Denmark's Queen Margrethe II has a pair of younger sisters. Both of them have always behaved impeccably. Princess Benedikte wed at age 24 to Richard 6th Prince of Sayn-Wittgenstein-Berleburg, who passed away in 2017. They had a son and two daughters. Interestingly, the marriage rules of the princely house are stricter than those of today's reigning monarchies. Therefore, Benedikte's son Gustav, who succeeded as the 7th prince, has been unable to marry his longtime love Carina Axelsson. Carina, however, is fully accepted as a member of the extended royal family, even wearing family jewels on occasion, and she manages the family castle. The youngest, Princess Anne Marie, was the first of the trio to marry when she wed the newly crowned King Constantine II of Greece just two weeks after her 18th birthday. The couple had three children in quick succession, but the third one was born in exile after the royal family fled the politically tempestuous country, eventually losing the crown. They later landed in London, where they are still based, and added two more children to their brood.
