I want to know the answer to the following question:
Who did Yaroslav's sons marry?
All the background I'm provided with is that "His daughters became queens of Hungary, France and Norway, his sons married the daughters of a Polish king and a Byzantine emperor (not to mention a niece of the Pope), while his granddaughters were a German Empress and (according to one theory) the queen of Scotland.". Is that enough to answer the question?
