Cynfyn ap Gwerystan (Cynfyn son of Gwerstan or Gwerystan; born c. 990[1]) was a Welsh nobleman and possible king of Powys,[2] principally known on account of his son Bleddyn ap Cynfyn, who established the House of Mathrafal over Powys thanks to a Saxon invasion in 1063.

His father was Gwerystan ap Gwaithfoed and his mother Nest ferch Cadell.[3][4] Cynfyn married Angharad, daughter of King Maredudd ab Owain of Dyfed.[5]

Interim King of Powys[edit]

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."

Wolcott further argues that Cynfyn was a caretaker monarch until 1033, when Iago ap Idwal of Gwynedd came of age and took the kingship.[6]

Children[edit]

With an unnamed Irish princess, daughter of Sitric Silkbeard c. 960 he had the following issue:

  • Eva ferch Cynfyn, c. 1018, who married Llewelyn ap Coel
  • Nest ferch Cynfyn, c. 1020, who married Ithel ap Coel, brother of Llewelyn
  • Iwerydd ferch Cynfyn, c. 1022

After the death of his first wife, probably in childbirth, he married Angharad, widow of Llywelyn ap Seisyll and had the following issue:
