I know that the answer to the question "Why did Grand Duchy of Lithuania become a famous place for noble Ruthenian families to get intermarried?" is in "In Ruthenia the nobility gradually gravitated its loyalty towards the multicultural and multilingual Grand Duchy of Lithuania after the principalities of Halych and Volhynia became a part of it. Many noble Ruthenian families intermarried with Lithuanian ones.". Can you tell me what it is?
