Of course there has accumulated a certain amount of legend about Brychan, and we cannot really be sure that such a person ever existed; that, in fact, the name is not really that of a clan, for Breogan, which is the same as the Welsh Brychan, was the reputed ancestor of one of the branches of the Scots or Irish who migrated, according to legend, from Spain to the Emerald Isle.[[1]]

What is true is that a certain Irish clan did invade and occupy Brecknock and Carmarthen, as well as Pembrokeshire, and that about 530 they were driven out of the two first counties, and that they thereupon invaded and occupied North-East Cornwall from Padstow harbour, and the north of Devon as far as Exmoor. This was not by any means a first descent. The whole coast had been a prey to invasions from Ireland for two centuries. On this occasion among the Irish-Welsh from Gwent and Brecknock came a great number of saints, that is to say, princes and princesses devoted to the ecclesiastical profession. The significance of this I shall explain presently.

I will here only point out that almost all the foundations of churches in North-east Cornwall were made by members of the same Gwent-Brecknock family. Is there, it may be asked, any Irish record of this invasion? We have a good many records of earlier forays and occupations of Britain by the Irish, but of this particular one only a somewhat confused legend. There was a certain Princess Earca, married to a king named Saran, in Ireland, who was much engaged in raids in Britain. She was the daughter of Loarn, king of Alba or Scotland, from whom Lorn takes its name, the date of whose birth is given by the Irish annalists as taking place in 434. He was, in fact, one of the Irish Ulster adventurers who invaded Scotland.

Earca ran away from her husband to be with Murtogh, a distant cousin of Saran, and she bore him four sons. The most noted of all was Murtogh MacEarca, who in time became king of Ireland. Saran then married Earca's sister, and by her became the father of S. Cairnech and Lurig, king of the Scots (Irish) in Britain. Murtogh having committed several murders in Ireland, fled for protection to his grandfather, Loarn, in Alba, and murdered him. Thereupon he was banished from what we now call Scotland. He went to his cousin S. Cairnech to bless his arms, as it was his intention to offer his services to one of the kings of Britain, and do as much fighting as came in his way. Before leaving Cairnech he murdered in cold blood his cousin Luirig, and carried off his wife.

In Britain this ruffian, we are told, became the father of Constantine and Goidel Ficht, who became the reigning princes in Cornwall.

Murtogh was back in Ireland in 488, for we find him there fighting; and he remained there stirring up strife, and a cause of bloodshed till he was elected king of Ireland in 508.

Now, Murtogh most certainly when he went to Britain led a body of adventurers like himself. He is said to have been the father of Goidel Ficht, who remained there as sovereign. Now, Goidel Fichti signifies the Irish Picts, neither more nor less, a generic name, and his fatherhood of the Irish Picts means no more than that his clan or horde, which swooped down on Cornwall and Wales, regarded themselves as Hy Murtogh.

It is rather remarkable that his cousin, the whole brother of S. Cairnech, was named Broechan or Brychan.

Now, in this story, attached to a perfectly historical character, I cannot but suspect that we have a reference to a descent on Wales and Cornwall in or about 470-480.

Perhaps it may interest the reader to hear what was the end of this ruffian.
