In all the world, Енніо (Ennio , Енніо , Aenius ) is a common male first name. The first name Енніо is habitual in Southern Europe, particularly Italy, where it is quite a common boy's name, Albania, where it is quite a rare male name, and Croatia. Not in comparison with a country's population, it is the most numerous in Italy, Brazil, and Guatemala. Very seldom, Енніо is the last name as well as the forename.
