Some persons were servants of all the saints, collectively; as Giolla-na-naomh, very frequent in Irish genealogies. In the Highlands it becomes Gille-ne-ohm, and thence has occasioned the modern surnames Niven and Macniven. They are, probably, all connected with the Welsh nen, sky.
This word, in Cymric, leads us to the name of Ninius, prince of Cumberland, who there established Christianity, and of Nennius the British historian; though these are too much disguised by the Latin to be easily recognized. St. Ninidh, the pious, was one of the Twelve Apostles of Ireland, and left a hand bell, which is still preserved in the county of Fermanagh. Another bell, kept as a tenure of land, is still extant in Galloway, and is said to have belonged to St. Ninian, who is called by the Irish, Ringan, a prince of Cumbrian birth, who became a monk, in 412 built the first stone church between the Forth and Clyde, earned the title of Apostle of the Picts, and died in 432; leaving Ninian and Ringan both to be Christian names in Scotland.
The great object of Keltic veneration was, however, St. Patrick. Nobody ventured to be Patrick alone, but many were Giolla Phadraig, or Mael Phadraig, and the descendants were Mag Giolla Phadraig, whence arises the surname Fitzpatrick, translating the Mac, and omitting the Gillie. Others, again, were Killpatrick; but it is not easy to tell whether this Kil is the contraction of Gillie, or territorial, from the Cell or Church of St. Patrick. The first syllable of Cospatric, or Gospatrick, the Christian name of the Earls of Northumberland in the tenth and eleventh centuries, is less easily explained; but I believe (on Mr. Lower’s authority) it is the Gossoon, the boy of St. Patrick.
St. Patrick’s pupil, Bridget, had her votaries in large numbers, Giolla Brighde, Gilbrid, Maelbridh, all now lost but for the occasional surnames of Macbride and Kilbride, which last is sometimes the Church of Bride. Possibly, too, the Scottish Gilbert may have been taken up as an equivalent to Gilbrid.
The great St. Columba, who established the centre of his civilizing and Christianizing efforts at Iona, had many a grateful disciple, as Gillecolumb, or Maelcolum. The latter form rose to the throne of Scotland in 936, when the father, who had thus dedicated his son to the missionary saint, retired into a convent. The second Malcolm was the persecutor of Lady Macbeth’s family, the third was Duncan’s grandson, he of the Great Head, who, by the help of his sweet wife, St. Margaret, was the first to lift Scotland out of her barbarism, and begin that assimilation with the English which was in full progress at the time of the death of his great grandson, Malcolm the Maiden, and perhaps was the reason why no more kings were called by this Keltic name, so puzzling to Latinizers, that in utter oblivion of St. Columb, they call it Milcolumbus. However, the people of Scotland have kept it up, and in 1385, Sir Malcolm Drummond received 400 francs from France, and is designated in the conveyance as Matorme Dromod! Callum is considered in the Highlands as the form of Malcolm, and Cailein of Colin. Probably Kilian, one of the Keltic missionary saints, popular in Germany, is another pronunciation of the word.
Secundinus was another pupil of St. Patrick, whom the Irish first made into Seachnall, and then termed their children Mael-seachlain, as his pupils. The great Irish king, Malachy with the collar of gold, was thus rendered to suit the weak Saxon capacity.
Cailleach-Coeimlighin and Gilla Coeimghin are the votaries of St. Kevin, a very unpromising object of hero-worship, if we were to believe the legend with which Moore and other moderns have quite gratuitously favoured Glendalough. Cœimghin itself means fair offspring.
Giolla Cheallaigh was common in honour of Ceallach, a very local saint, of royal birth, who was educated by St. Kieran. On his father’s death, he was about to ascend the throne, when his tutor interfered, probably considering this an infraction of his vows, and on his persisting, laid him under a curse, after the usual fashion of Irish saints. He lost his kingdom, and became a bishop, but resigned his see for fear of his enemies, and retired to a hermitage on Lough Con, where, however, he was murdered by four ecclesiastical students, whose names all began with Maol. His corpse was hidden in a tree, where for once it did not show the incorruptibility supposed to be the property of sanctity. The murderers were all put to death on an eminence, called from them Ardna-maol, or hill of the shavelings, and his admirers have resulted in the surname O'Killy-kelly, or, for short, Kelly.
Scotland had several instances of bishop’s servant, Gillaspick in Scotland, or in Northern Ireland, Giolla Easbuig, the Keltic form of episcopus. Gillaspich Campbell, already Scotticized enough to have been christened by this Gaelic term, married Aioffe O'Duinne, the daughter of the line of Diarmid; and thenceforth Gillaspick, or Gillespie, was the hereditary Christian name in the family, till, in the twelfth century, his fourth descendant called himself Archibald, and thenceforth the heads of the house of Campbell have been Archibald to the Lowlands, to their own clan, Gillespik. It is a curious fact that Gillespie Grumach and his son, the two Covenanting Argyles, should thus have proclaimed themselves ‘Bishop’s gillies.’ Gillespie has become a frequent surname in Scotland.
Maelgwn, or Maelgwas, was his successor in Powys and Gwynned, and is desperately abused by the indignant Gildas for all manner of crimes; while even Taliessin, who praises his beauty, rebukes his licentiousness. Three centuries later, a bard alleges that he hid himself in a wood, waylaid and carried off the wife of King Arthur. In the twelfth century, Caradoc, abbot of Llancarven, adds that Arthur besieged him in his castle, and had challenged him to single combat, when the sage Gildas and the abbot of Glastonbury interposed, and obtained the lady’s restoration. Walter of Oxford adds that this Maelgwn reigned after King Arthur, and finally died of terror in a convent, having seen the Yellow Spectre, namely the plague, through the chinks of the church door. Dr. Owen Pugh further tells us, that Jack-in-the-Green, on May-day, was once a pageant representing Melva, or Melvas, king of the country now called Somersetshire, disguised in green boughs, as he lay in ambush to steal King Arthur’s wife as she went out hunting.
