In the world, سيليان (Cillian 
, Ciljan 
, سيليان) is a rare boy's first name. The first name سيليان is characteristic of Ireland, where it is quite a common masculine name, Australia, where it is a very rare masculine name, and the United Kingdom, where it is a very rare principally boy's, but very infrequently girly name. Very seldom, سيليان is the last name as well as the forename.
