Padarn Beisrudd

Padarn Beisrudd ap Tegid , was the son of a man named Tegid ap Iago, who may have been born with the Roman name of Tacitus. Padarn is believed to have been born in the early 4th century in the Old North (or Hen Ogledd) of Roman Britain. According to Old Welsh tradition, his grandson, King Cunedda, came from Manaw Gododdin, the modern Clackmannanshire region of Scotland. It is possible that Padarn ruled as an independent tribal king.

The coat of Padarn is one of the Thirteen Treasures of the Island of Britain. The coat is said to perfectly fit any well-born nobleman, but not a churl. The Life of Saint Padarn confuses this Padarn with the saint, and contains a story about how King Arthur tried to steal his tunic and became a Christian afterward.
