Europe’s royal shuffling is rife with things like that. Most royal families have blood ties with each other, and historically have agreed to place one of theirs on another countries throne to keep collective hold on the continent.
“The German Kaiser (Wilhelm II), Russian Czar (Nicholas II), and English King (George V) were all first cousins. Their grandmother was England’s Queen Victoria, making the English and German kings first cousins. The English and Russian kings were also first cousins, as their mothers were sisters.”
