Catan (Cathan, Cadan, Ceddan, or Keddan), an early bishop and confessor, tutor of St. Blane, has his festival in the Irish calendars on Feb. 1, and in the Scotch on May 17. He is said to have been first connected with St. Patrick in Ireland, and then went to Scotland and settled in Bute, where he built his cell at Kilcathan, or Kilchattan, and educated his nephew St. Blane. Colgan thinks he flourished about A.D. 560, but others place him even in the 7th century. According to the Irish tradition he was buried in Ireland, and St. Cadan's tomb is to this day shown beside the Church of Tamlaght Ard, County Londonderry; but according to the Scotch he lies at Kilchattan. His memory is honored by many dedications in the west of Scotland. There was also a Catan who died abbess of Kildare, A.D. 853.
