In all the world, Milein (Милен 
, ميلين 
, Milein 
) is quite a rare primarily boy's, but very infrequently girly first name. The given name Milein is characteristic of Bulgaria, where it is quite a common male name, Syria, where it is a rare female name, and Russia, where it is a very rare gender-neutral name. Much less frequently, Milein is the last name as well as the forename.
