CYLLIN ap Caradoc and Dareara

CYLLIN ap Caradoc. (St. Cyllin, Cyllinus)(Coellyn). King of Siluria (now Monmouthshire).
Born (about 40 AD-S?)(in 40 AD-S7)(about 100 A.D.-S2); son of Caradoc (Caratacus) ap Cunobelinus.

Since Caradoc ap Cunobelinus and Caradoc ap Bran are so confused together, Cyllin is often said to be the son of both, but son of Caradoc ap Cunobelinus appears to be the most likely.

Said to be the last Pendragon of Great Britain. Pendragon or Pen Draig (pronounced Thriag), meaning in Welsh head dragon or chief dragon, a figurative title referring to status as a leader. (S6).

Richard Williams Morgan claimed that a reference to him as a son of Caratacus was found in the family records of Iestyn ab Gwrgant and used this as evidence of early entry of Christianity to Britain; "Cyllin ab Caradog, a wise and just king. In his days many of the Cymry embraced the faith in Christ through the teaching of the saints of Cor-Eurgain, and many godly men from the countries of Greece and Rome were in Cambria. He first of the Cymry gave infants names; for before, names were not given except to adults, and then from something characteristic in their bodies, minds, or manners." (S6).

His brother Linus the Martyr, his sister Claudia (Eurgan) and her husband Rufus Pudens aided the Apostle Paul in the Christian Church in Rome, as recorded in II Timothy 4:21 and Romans 16:13 and visited him in his cell. (Rufus Pudens and St. Paul are said to be half-brothers, with the same mother but different fathers. "His mother and mine." She thus appears to have been the mother of an elder son, Paul, by a Hebrew husband, and a younger son, Rufus, by a second marriage with a Roman Christian.)

For some years after the death of Peter in 66 A.D. and of Paul in 68 A.D., both Clement and Linus led respective groups of Christians in Rome. Eventually Linus departed and joined his royal kindred in Glamorgan.

Sainted by the early Church of Britain.

Reference to Saint Cyllin is also given in Iolo Morganwg's "Third series" of forged Welsh Triads. He is also discussed in the works of Rice Rees, Jane Williams, Sabine Baring-Gould and John Williams (Ab Ithel) as brother of Saint Eigen and father of King Coel. He is also noted in a manuscript giving the genealogy of Taliesin from the collection of Thomas Hopkin of Coychurch along with one from the Havod Uchtryd collection where he is called Cynan, a name often associated with Conan Meriadoc. (S6).
