Prince Filiberto of Savoy, 4th Duke of Genoa (Filiberto Lodovico Massimiliano Emanuele Maria; 1895 – 1990) was the fourth Duke of Genoa and a member of the House of Savoy.
I knew a FILIBERTO. He was so handsome. His family called him Fili but friends called him Beto. Although not common, you do hear this name in many Spanish-speaking countries, especially in Mexico.
