medieval Irish saint
Feast: 13 November (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Saint Caillin (fl. c.570) was an Irish medieval saint and monastic founder. His Feast day is celebrated on 13 November. The patron saint of Fenagh, County Leitrim, Caillin was born in the 6th century and founded a monastic settlement at Fenagh. His history was given in the Old Book of Fenagh (no longer extant; material included in the Book of Fenagh). The Annals of the Four Masters mentioning him living in 464 is based on the late 16th century Book of Fenagh, which is a piece of literature considered unreliable without other historical records. Caillín's siblings lived in the second half of the 6th century, so it is likely Caillín lived at the same time.
