I was wondering 'cause i read somewhere that an niece of the last byzantine emperor married a russian tsar. And that the queen's great-great-whatever was related to the tsars. Just wasn't sure if it was the same family.
Zoe Palaiologina, the wife of Ivan the Great, was the niece of Constantine XI, the last Byzantine emperor, and the granddaughter of Manuel II. Their great-grandson was the aforementioned Tsar Feodor I, last of the Rurik dynasty.
Edit: That is, Feodor was the great grandson of Zoe and Ivan, not Zoe and Manuel. Watch your antecedents!
