St Cadoc's Church, Trevethin

Seems from his Wikipedia entry that Saint Cadoc got around a bit. Which, a for 5th and 6th century traveler without access to EasyJet or RyanAir, was pretty impressive.

Now, if you're paying attention:

The genealogy of the blessed Cadoc arises from the most noble emperors of Rome, from the time of the incarnation of Jesus Christ, Augustus Cesar, in whose time Christ was born, begat Octavianus, Octavianus begat Tiberius, Tiberius begat Caius, Caius begat Claudius, Claudius begat Vespasian, Vespasian begat Titus, Titus begat Domitian, Domitian begat Nero, under whom the apostles Peter and Paul suffered, Nero begat Trajan, Trajan begat Adrian, Adrian begat Antonius, Antonius begat Commodus, Commodus begat Meobus, Meobus begat Severus, Severus begat Antonius, Antonius begat Aucanus, Aucanus begat Aurelian, Aurelian begat Alexander, Alexander begat Maximus, Maximus begat Gordian, Gordian begat Philip, Philip begat Decius, Decius begat Gallus, Callus begat Valerian, Valerian begat Cleopatra, Cleopatra begat Aurelian, Aurelian begat Titus, Titus begat Probus, Probus begat Carosius, Carosius begat Dioclesian, who perscuted the Christians throughout the whole world; for in his time the blessed martyrs Alban, that is Julian, Aaron, and many others suffered. Dioclesian begat Galerius, Galerius begat Constantine the Great the son of Helen, Constantine begat Con- stantius, Constantius begat Maximianus, with whom the British soldiers went from Britain, and he slew Gratian the Roman emperor, and held the government of all Europe; and he did not dismiss the soldiers, which he brought with him from Britain to return to their country on account of their bravery, but gave them many provinces and countries, that is from the pool which is on the top of the mountain of Jupiter to the city named Cantguic, and until the western mound that is Cruc Ochideint; and from those soldiers arose a nation which is called Lettau.1 Maximianus therefore begat Owain, Owain begat Nor, Nor begat Solor, Solor begat Glywys, Glywys begat Gwynlliw, Gwynlliw begat the most blessed Cadoc of whom we are speaking.
