All over the world, Frain (Frain 
, Fregna 
, Фрейн 
) is a rare primarily male, but very infrequently female first name. The given name Frain is characteristic of Bolivia, where it is a rare boy's name, Peru, and Tanzania, where it is a very rare male name. Not in comparison with a country's population, it is commonest in Latin America and the Caribbean, particularly Mexico, Peru, and Bolivia. More frequently, Frain is the last name as well as the forename.
