Petroc Baladrddellt
Petroc Baladrddellt (also known as Pedrog, or Pedrogl Paladrddellt) was a 7th-century King of Dumnonia (now the English West Country).
Monarch
According to the Welsh pedigrees in the Bonedd y Saint or "Genealogies of the Saints", Petroc Baladrddellt ap Clemen was the son of Clemen (or Clement) ap Bledrig, his epithet meaning "Splintered Spear". It is thought he was born in c. 600 and succeeded to the Dumnonian throne after his father in c. 630, reigning at a time of continued West Saxon aggression which had also affected his father. His death may have occurred in c. 652 when King Cenwalh of Wessex is said to have defeated the Britons at the battle of Bradford-on-Avon, taking large swathes of Dorset and Somerset. Other sources are unclear as to whether this battle was civil war between Cenwalh and his kinsman Cuthred, or against the Welsh or the Mercians or both.
Family
King Petroc may have had two sons, Culmin (or Cwlfyn) and Progmael (or Brochwel). In the later case, Culmin is given as the son of Progmael and grandson of Petroc, as given in the Book of Baglan. If so, Prince Progmael appeared to have predeceased his father Clemen ap Bledric who died in c.654, at Y Ferwig in Ceredigion, leaving the Dumnonian kingdom to Culmin.
