 In more modern times, Cassius Clay was an abolitionist and also the birth name of boxer Muhammad Ali. It was chosen for their sons by singer Bobby Brown and Getty heir/actor Balthazar Getty. Vanessa Marcil and Brian Austin Green used the nouveau Kassius spelling for theirs. With these namesakes, it's no surprise this name has become popular in recent years.
