Caedan is of Irish origin, derived from the ancient Irish name Caden, which means "from Cathain's family." It is believed to have been brought to England by Norman invaders and has since become more prevalent in English-speaking countries. The name gained popularity in recent years, particularly in Australia and the United States. Caedan is considered a modern variation of traditional names like Kadeen or Cadden, offering a unique yet familiar option for parents seeking a distinctive name for their child.
