  === Life Sketch ===
  His father was Gwerystan ap Gwaithfoed and his mother Nest ferch Cadell.[3][4] Cynfyn married Angharad ferch Maredudd, daughter of Maredudd ap Owain, king of Dyfed.[5]
  
  Wolcott states that "When he was born c. 985, there was no expectation Cynfyn would ever become a king. His ancestors had been among the leading men of Powys for hundreds of years, but the kingdom had been ruled by another ancient family which was still in power. His father had married the daughter, and only child, of King Cadell ap Brochwel II. But Cadell had brothers and nephews eligible to rule after his death; seldom did a Welsh kingship descend through female lines, and never if there was an eligible qualified male heir. But such a circumstance appears to have occurred in 1023, when the existing king died (or was killed) fairly early in his life and at a time when both his son and other qualified males in the Royal Family were too young for kingship."
  
  However, an ancestor of Cynfyn was Cynwrig, son of Tegonwy, a descendant of Casnar Wledig who in some cases is made son of Caderyn, while in more ancient documents he is son of Gloyw Gwlat Lydan and Great Grandson of Ludd ap Beli Mawr, making him a descendant of a direct patrilineal line from the house of Gwertherion or the Celtic Kings of Britain, which could explain why Gwerstan was chosen to marry Nest ferch Cadell.[6]
  
  Wolcott further argues that Cynfyn was a caretaker monarch until 1033, when Iago ap Idwal of Gwynedd came of age and took the kingship.[7] A dictionary of biography of eminent Welshmen

  ________________________________
  
  Llywelyn ap Seisyll (d 1023), kinf of Deheubarth and Gwynedd. Nothing is known of his father, but his mother, Prawst, was, according to late pedigrees, the daughter of Elisedd, a younger son of Anarawd ap Rhodri Mawr. Since he himself m. Angharad, daughter of Maredudd ab Owain ap Hywel Dda, he had distant claims to succession in both Deheubarth and Gwynedd, which in the circumstances of the time could be translated into reality by a leader of force and ambition. Such a man was Llywelyn, and by his defeat of the usurper, Aeddan ap Blegywryd, in 1018, and of Rhain, an Irish pretender in 1022, he became master of the south. He also extended his rule for a few years over a large part of Wales, a memorable period in Welsh annals judging from the entries in the chronicle. His chief claim to fame, however, is the fact that he was the father of Gruffudd ap Llywelyn, whose notable career was made possible by the example of the father, and whose claim to power was largely based on the short 'de facto' overlordship of Llywelyn. [Dictionary of Welsh biography p600-601]
  
  _______________________________
  
  Llywelyn ab Seisyll or Seisyllt (d 1023?0, king of Gwynedd, was a Welsh chieftain, not of the royal line, who married, if the tradition of a later time can be trusted, Angharad, daughter of Maredudd, son of Owain, son of Howel Dda, and thus became associated with the greatest house in South Wales. Llywelyn lived in a time of exceptional confusion. In North Wales the stock of the royal house of Gwynedd had been replaced on the throne by a vigorous usurper, Aeddan ab Blegywryd. The inroads of the Danes and the advances of the English power were fatal to the settled rule in North and South Wales alike. Llywelyn managed, however, to slay Aeddan and his four sons. This event probably happened in 1017, or possibly in 1018, the year after the succession of Cnut in England. Llywelyn now took possession of the throne of North Wales, thus bringing in the family of Howal Dda in the person of his descendants, and representing some sort of triumph of South Welsh over North Welsh. Llywelyn's brief reign was one of exceptional prosperity. He is styled 'supreme king of Gwynedd, and the chief and most renowned king of all the Britons.' 'In his time,' wrote the Welsh chronicler, 'it was usmacl of the elders of the kingdom to say that his dominion was, from one sea to the other, complete in abundance of wealth and inhabitants, so that it was supposed that there was neither poor nor destitute in all his territories, nor an empty hamlet, nor any deficiency.' This indicates that under Llywelyn that restoration of the North Welsh power began which attained its highest point in the reign of his more famous son Gruffudd ab Llywelyn (d 1068). But in 1020 or 1022 Llywelyn had to face a formidable enemy. An Irish imposter named Rein claimed to be the son of Maredudd ab Owain, Llywelyn's father-in-law, formerly king of South Wales. Rein was so successful as to obtain general recognition throughout Deheubarth (South Wales). Llywelyn was still sufficiently connected with southern affairs to fear the growth of his power. He accordingly marched with an army into South Wales. Rein, 'after the manner of the Irish,' 'prouldy and ostentatiously' exhorted his men to fight, with many boasts of victory. After a sharp struggle the men of Gwynedd prevailed, and Rein fled 'shamefully, like a fox.' The battle was fought at Abergwili, near Carmarthen. Rein was heard of no more, and perhaps perished in the battle. Llywelyn, by cruelly devastating the south, vindicated his position as chief king of the Welsh. Next year he died. The date is either 1021 or 1023, probably the later year. He left a brother named Cynan, who was slain four years later. His son Gruffydd ab Llywelyn (d 1068) was for a time driven from Gwynedd by a restoration of the rightful line. The Gwentian chronicler celebrates Llywelyn's virtues in war and peace, and couples him with his son as 'the noblest princes that had been until their time in Wales.'

  The son of an otherwise completely unrecorded Seisyll and Prawst, daughter of Elisse, a younger son of Anarawd ap Rhodri, King of Gwynedd, who married Angharad Ferch Maredudd, daughter and heiress of Maredudd ab Owain ap Hywill Dda, King of Deheubarth and Gwynedd and succeeded his father-in-law in 999. He made himself ruler or overlord of all Wales, defeating Aeddan ap Blegywryd and his four sons in 1018 and an Irish pretender Rhain, who claimed he was a son of King Maredudd, in 1022. He died in the following year, leaving a son Gruffydd, who later obtained the throne. The Brut y Tywysogion calls Llywelyn 'the supreme and most praiseworthy king of all Britain. And in his time, as the old men were wont to say, the whole land from the one sea to the other was fruitful in men and in every kind of wealth, so that there was no one in want nor anyone in need within his territory; and there was not one township empty or desolate.'

  === Life Sketch ===
  His father was Gwerystan ap Gwaithfoed and his mother Nest ferch Cadell.[3][4] Cynfyn married Angharad ferch Maredudd, daughter of Maredudd ap Owain, king of Dyfed.[5]
  
  Wolcott states that "When he was born c. 985, there was no expectation Cynfyn would ever become a king. His ancestors had been among the leading men of Powys for hundreds of years, but the kingdom had been ruled by another ancient family which was still in power. His father had married the daughter, and only child, of King Cadell ap Brochwel II. But Cadell had brothers and nephews eligible to rule after his death; seldom did a Welsh kingship descend through female lines, and never if there was an eligible qualified male heir. But such a circumstance appears to have occurred in 1023, when the existing king died (or was killed) fairly early in his life and at a time when both his son and other qualified males in the Royal Family were too young for kingship."
  
  However, an ancestor of Cynfyn was Cynwrig, son of Tegonwy, a descendant of Casnar Wledig who in some cases is made son of Caderyn, while in more ancient documents he is son of Gloyw Gwlat Lydan and Great Grandson of Ludd ap Beli Mawr, making him a descendant of a direct patrilineal line from the house of Gwertherion or the Celtic Kings of Britain, which could explain why Gwerstan was chosen to marry Nest ferch Cadell.[6]
  
  Wolcott further argues that Cynfyn was a caretaker monarch until 1033, when Iago ap Idwal of Gwynedd came of age and took the kingship.[7] A dictionary of biography of eminent Welshmen

  ________________________________
  
  Llywelyn ap Seisyll (d 1023), kinf of Deheubarth and Gwynedd. Nothing is known of his father, but his mother, Prawst, was, according to late pedigrees, the daughter of Elisedd, a younger son of Anarawd ap Rhodri Mawr. Since he himself m. Angharad, daughter of Maredudd ab Owain ap Hywel Dda, he had distant claims to succession in both Deheubarth and Gwynedd, which in the circumstances of the time could be translated into reality by a leader of force and ambition. Such a man was Llywelyn, and by his defeat of the usurper, Aeddan ap Blegywryd, in 1018, and of Rhain, an Irish pretender in 1022, he became master of the south. He also extended his rule for a few years over a large part of Wales, a memorable period in Welsh annals judging from the entries in the chronicle. His chief claim to fame, however, is the fact that he was the father of Gruffudd ap Llywelyn, whose notable career was made possible by the example of the father, and whose claim to power was largely based on the short 'de facto' overlordship of Llywelyn. [Dictionary of Welsh biography p600-601]
  
  _______________________________
  
  Llywelyn ab Seisyll or Seisyllt (d 1023?0, king of Gwynedd, was a Welsh chieftain, not of the royal line, who married, if the tradition of a later time can be trusted, Angharad, daughter of Maredudd, son of Owain, son of Howel Dda, and thus became associated with the greatest house in South Wales. Llywelyn lived in a time of exceptional confusion. In North Wales the stock of the royal house of Gwynedd had been replaced on the throne by a vigorous usurper, Aeddan ab Blegywryd. The inroads of the Danes and the advances of the English power were fatal to the settled rule in North and South Wales alike. Llywelyn managed, however, to slay Aeddan and his four sons. This event probably happened in 1017, or possibly in 1018, the year after the succession of Cnut in England. Llywelyn now took possession of the throne of North Wales, thus bringing in the family of Howal Dda in the person of his descendants, and representing some sort of triumph of South Welsh over North Welsh. Llywelyn's brief reign was one of exceptional prosperity. He is styled 'supreme king of Gwynedd, and the chief and most renowned king of all the Britons.' 'In his time,' wrote the Welsh chronicler, 'it was usmacl of the elders of the kingdom to say that his dominion was, from one sea to the other, complete in abundance of wealth and inhabitants, so that it was supposed that there was neither poor nor destitute in all his territories, nor an empty hamlet, nor any deficiency.' This indicates that under Llywelyn that restoration of the North Welsh power began which attained its highest point in the reign of his more famous son Gruffudd ab Llywelyn (d 1068). But in 1020 or 1022 Llywelyn had to face a formidable enemy. An Irish imposter named Rein claimed to be the son of Maredudd ab Owain, Llywelyn's father-in-law, formerly king of South Wales. Rein was so successful as to obtain general recognition throughout Deheubarth (South Wales). Llywelyn was still sufficiently connected with southern affairs to fear the growth of his power. He accordingly marched with an army into South Wales. Rein, 'after the manner of the Irish,' 'prouldy and ostentatiously' exhorted his men to fight, with many boasts of victory. After a sharp struggle the men of Gwynedd prevailed, and Rein fled 'shamefully, like a fox.' The battle was fought at Abergwili, near Carmarthen. Rein was heard of no more, and perhaps perished in the battle. Llywelyn, by cruelly devastating the south, vindicated his position as chief king of the Welsh. Next year he died. The date is either 1021 or 1023, probably the later year. He left a brother named Cynan, who was slain four years later. His son Gruffydd ab Llywelyn (d 1068) was for a time driven from Gwynedd by a restoration of the rightful line. The Gwentian chronicler celebrates Llywelyn's virtues in war and peace, and couples him with his son as 'the noblest princes that had been until their time in Wales.'

   Note: Good source, but there is not mention of any Idwallan son of Einon - need page # The second edition Ordnance Survey map (1899) shows ‘Pant Câd-Einion Site of Battle (A.D.982)’ at SS 9494 8059. This is absent from the first edition map of 1877. The battle was likely added on the basis of material found in the unreliable Gwentian Brutforged by Iolo Morgannwg in the 1790s. 982 Einion, son of Owain, went to Gorwennydd, where the action of Pencoed Colwynn took place (Owen, 35). How Pencoed Colwynn became Pant Câd-Einion is uncertain. (same source)
