The nature of Ninian's identity is uncertain, and historians have identified the name "Ninian" with other historical figures. A popular hypothesis proposed by Thomas Owen Clancy, a researcher and professor of Celtic studies, posits that Ninian can be identified with three other historical figures: Saint Finnian of Moville, Saint Finnian of Clonard, and Saint Finbarr of Cork. Linguistic variations across the territories associated with each saint have provided evidence that the Ninian preserved in literary tradition originated from this individual. This article discusses the particulars and origins of what has come to be known as the "traditional" stories of Saint Ninian.
