Worldwide, Эрно (Erno 
, Empu 
, Ernö 
) is quite a rare principally masculine, but very seldom feminine first name. The forename Эрно is habitual in Finland, where it is quite a rare boy's name, Romania, and Hungary. Not in comparison with a country's population, the name is most common in Indonesia, Brazil, and the Democratic Republic of the Congo. Much less frequently, Эрно is the last name as well as the forename.
