Cynddylan

Cynddylan, or Cynddylan ap Cyndrwyn was a seventh-century Prince of Powys associated with Pengwern. Cynddylan is attested only in literary sources: unlike many kings from Brittonic post-Roman Britain, he does not appear in the early Welsh genealogies or other historical sources. The son of King Cyndrwyn, Cynddylan is described in the probably seventh-century poem Marwnad Cynddylan and seems to have been a chieftain in Powys.
