In the entire world, Eii (Eii 
, Eaii ) is quite a common unisex first name. The first name Eii is characteristic of Uruguay, where it is quite a common epicene name, India, where it is a rare principally male, but scarcely feminine name, and Japan, where it is a rare gender-neutral name. Much less frequently, Eii is the last name as well as the forename.
