F.L. Molloy, Parish of Clonmany, 1814;
‘The titular saint, or as some express it, the guardian, of this parish, is Columbkill. The 9th of June is his festival day, and is observed most ceremoniously by the old people in the parish: on that day they circumambulate certain places, repeating certain prayers, deified, as it were, for him.
They formerly drove down their cattle to the beach, on that day, and swam them in that part of the sea, into which runs the water of St Columb’s well, which is thereby made holy-water; but this custom, of late, has not been practised.
There is also a traditional story told here, that the earth of a little hillhock (tempo desh,) on the right of the road leading from the chapel to the church, formerly expelled all mice and rats, until the earth of it was vended, when its expelling powers ceased; still, however, they carry all their dead around it, as being an ancient custom.
There is a circular flat stone in the centre of the church-yard, about fourteen inches in diameter, on which are two round hollow places, which they say are prints of Saint Columb’s knees. On that day mass used to be celebrated, but of late, I believe, it has being discontinued.’
