Morgwn was the native name of the heresiarch, who called himself by the Greek equivalent Pelagius, and thus named the Pelagian heresy. Some writers say that sundry heretic names lingered about the Spanish Visigoths after their union with the Church, and instance both Ario, a distinguished author, and Pelayo, the Asturian Robert Bruce, as instances of names so borne. However this may be, Morgan has continued, even to the present day, to be very common in Wales.
Morvryn may be sea-king. “Morolt with the iron mace,” as romance calls him, the brother of Yseulte, who was killed by Sir Trystan, is called Morogh by his own countrymen in Ireland. It is the contraction of Muireadhach, or sea protector, a favourite Irish name, though, after degenerating into Morogh, it was usually rendered into Morgan, and so continues in modern Ireland. It is perhaps the same with Meriadek, or Meiriadwg, the title of Conan, the chieftain who is said to have colonized Brittany, and also with the Welsh Meredith, both as a Christian and a surname. In Ireland, the sons of Morogh became O'Muireadaig, and then contracted into Murray. Muredach is said to have reigned over the Scots from 733 to 736, and is transformed into Murdach, Murochat, Muirtec, Mordacus. It must have become mixed with Muircheartach, from ceart (a right), which has produced Moriertagh, Murtagh, or Morty, as a Christian name in Ireland; but it is now made into Mortimer. It is Murdoch in Scotland, once very common, and not yet extinct, and the North, adopting it with other Keltic names, calls it Kjartan.
Muirgis, once common in Ireland, is rendered by Maurice, or Morris, and Murchada has become Murphy.
And there is a name, still very common in the North of England, that I cannot help connecting with some of these, namely Marmaduke, which appeared among the chivalry of England about the thirteenth century, and has never become extinct. It is most likely a corruption of one or other of the sea names, in fact, it is not far from Muireadach; or it may be the offspring of the Scottish title, Maormar, from maor, a steward or officer, and mor, great, thus meaning the great officer of the crown, the term which prevailed before the Saxon Thegn or Danish Earl displaced it.[[106]]

Section VIII.—Llew.
We find Llew, lion, naming Lleurwg ab Coel ab Cyllyn, also called Llewfer Mawr, the great light, and correctly translated by the Latin Lucius, the king who is said to have sent messengers to Rome to bring home Christianity, though some think Lucius a mere figment of Roman writers accepted by the bards.
Llew is the name given in Welsh genealogies to the king of the Orkneys, who married King Arthur’s sister, and was the father of Gwalchmai.
