Colgan says, that in our Menologies there are eight Cronans, and eighteen Mochuas, whose feasts are distinct; and, in almost all instances, the same saint is at one time named Cronan, and at another place, Mochua. Thus, in the Martyrologies of Tallagh, Marianus Gorman and Donegal, at the 28th of April, St. Cronan of Roscrea is called Mochua. In like manner, at the 22nd of June, St. Cronan, Abbot of Ferns, is called Mochua. Likewise, at the 30th of March, Mochua, Abbot of Balla, and at the 6th of August, St. Mochua of Clondalkin, are called by the name of Cronan. St. Oengus the Culdee, in his Homynomous Saints, book i., chapter xix., numbers more than fifty saints, bearing the designation Mochua, many of whom are called by the name of Cronan, in the aforesaid martyrologies. See Colgan’s “Acta Sanctorum Hiberniae,” X. Februarii, n. 2, p. 304.

Cronanus, vel est Mochua de Miliuc, id est, Cronanus filius Mellani de Glaismor in Desiis Momoniee, & Lismorioe colitur : vel Glaismor est Ecclesia juxta Surdum ad austrum.” A comment is added, that Glasmor was a church, near Swords, to the south, and that the Northmen came from Inbhear Domnann one night, and slaughtered St. Cronan with all his cenobites, so that not one of his family escaped.

The Life of St. Carthage states, that our present St. Cronan or Mochua had been, from his youth, a monk at Rathan. Our saint is said to have been the first, who made his religious profession, under St. Carthage, in the famous monastic establishment of Rathen ; and, it is on record, that eight hundred and seventy-seven monks were at one time subject to this very distinguished abbot’s spiritual supervision. Here, deriving every advantage from the training of this great saint, Cronan made considerable progress in virtue. At length, he was placed by St. Carthage, over an establishment, near Rathen. This place is called Cluain Dachran. We are told, this locality is identical with Clonrane, in Westmeath county. When Cronan was there appointed, he had been informed, that Cluain Dachran would neither be the place of his death, nor of his resurrection.

At the same time, or subsequently, he was placed in charge of Glassmore church, about four miles north of Youghal, in the barony of Decies within Drum, and in the present county of Waterford. It was situated, not far from the noble Blackwater River.

CRONAN, of Glais-mor in Deisi-Mumhan, and of Lis-mor. Or Glais-mor, a church that was by the side of Sord to the south, until the foreigners of Inbher Domhnann came to him and killed him and all his people in one night, so that not one of them escaped without being destroyed; and thus were they martyred.

This saint was venerated, likewise, and on the same day, in Scotland. There, however, he is not classed with the martyrs. The holy confessor, Cronan, in Ireland, is set down at the 10th of February in the Kalendar of Drummond, as having departed to Christ.
