In the world, สายสวรรค์ (สายสวรรค์ , Saisawan ) is a rare largely girly, but uncommonly boy's first name. The first name สายสวรรค์ is characteristic of South-eastern Asia, particularly Thailand, where it is a rare largely feminine, but infrequently masculine name. Very seldom, สายสวรรค์ is the last name as well as the forename.
