Croine (or Crone) is the name of several female Irish saints, of whom the following are the best known:
1. A virgin, commemorated January 27. She was of the race of Maine, son of Niall of the Nine Hostages, and was venerated at Cill-croine (Kilcron) in Ui-Maine, County Galway; but beyond this we have no information.
There were others of the same name, and the ruins of the Church of St. Croine, virgin, of Kill-Crony or Kilcroney, in the parish of Kilmacanoge, bar. Rathdown, County Wicklow, still exist in the disused churchyard. At January 27 the Mart. Tallaght has the feast of "Croni Innse Locha Crone" (Todd and Reeves, Mart. Doneg. page 29; Colgan, Acta Sanctorum, page 267 n.; O'Hanlon, Irish Saints, pages 455, 456; Kelly, Cal. of Irish Saints, page 13).
2. Beg (Little), of Tempull-Croine, virgin, commemorated July 7, was the daughter of Diarmaid, son of Garvan, of the race of Conall Gulban, son of Niall of the Nine Hostages. She is given as Cronia by Colgan, among the saints descended from Conall Gulban, the parent-stem of St. Columba, and her church was situated in Tyrconnel (Todd and Reeves, Mart. Doneg. page 189; Colgan, Tr. Thaum. page 480 n.).
