Elena, sometimes called (and sung of) as Maria Elena, was the second Queen of Italy. She married Victor Immanuel II and when Umberto ( Humbert) was assasinated, she became Queen of Italy, her husband the King. Elena was of Montenegrin ancestry and converted to Roman Catholicism. Other than that, she was a tall and beautiful woman and on the style more of Sophia Loren than the Rose of Fair Italy. At all events she was a popular monarch, as the song indicates. Elena died in l952 and somewhat oddly was buried in Montpelier in France. Is this the Elena you seek?
