Derived from Christian or a variant of Cassian
Kassen is a rare name likely functioning as a modern phonetic variant of Cassian, meaning 'hollow,' or as a Scandinavian diminutive form of Christian, meaning 'follower of Christ.' It has emerged as a contemporary choice for parents seeking a unique alternative to names like Mason or Karson. Its usage is primarily modern and lacks a deep independent etymological history.
