Throughout the world, Gwion (Gwion 
) is a very rare primarily boy's, but scarcely girly forename. The first name Gwion is habitual in Northern Europe, particularly the United Kingdom, where it is a rare principally male, but very infrequently female name. Very seldom, Gwion is the last name as well as the forename.
