All over the world, สมรธรรม (สมรธรรม 
, Samontham ) is a very rare primarily girly, but very seldom masculine first name. The first name สมรธรรม is habitual in South-eastern Asia, particularly Thailand, where it is a very rare principally girly, but scarcely boy's name. Much less frequently, สมรธรรม is the last name as well as the forename.
