Throughout the world, Trian (Trian 
, เตรียน 
) is quite a rare unisex forename. The first name Trian is habitual in Indonesia, where it is quite a rare dominantly masculine, but seldom girly name, Romania, where it is a rare male name, and Israel, where it is a rare epicene name. Not in comparison with a country's population, it most frequently occurs in Indonesia, India, and Romania. Very seldom, Trian is the last name as well as the forename.
