Globally, Timbul (Timbul 
) is quite a common principally male, but very infrequently girly forename. The first name Timbul is habitual in South-eastern Asia, particularly Indonesia, where it is quite a rare principally male, but very infrequently female name, and Philippines, where it is a very rare unisex name. Much less frequently, Timbul is the last name as well as the forename.
