Jewish Immigrant Marriage

I've been listening to the memoirs of Tony Judt, a British Jewish intellectual whose grandparents all came from eastern Europe. In 1965 he won a scholarship to King's College Cambridge. His parents opened the telegram and excitedly called him at a friend's house to tell him the news, then insisted that he come home to celebrate. He arrived home to find his parents in the middle of a furious argument. It turned out they were arguing over whose family had supplied the smarts that allowed their son to be such a good student.
