Fionnlagh MacCailein

He was part of the circle of Robert Stewart, Duke of Albany, and was one of the many clerics from west and central Gaelic-speaking Scotland who benefited from the latter's patronage.

[3] On 15 September 1402 Pope Benedict XIII provided Fionnlagh to a canonry (with the expectation of a prebend) in the diocese of Dunkeld; the mandate of provision contains information much about Fionnlagh, informing us that he was a priest, confirming that he possessed a bachelor's degree in canon law, while also stating that he was Archdeacon of Dunblane.

[3] At that date he is found back in Scotland as a full bishop attending a church council at Linlithgow.

[3] In 1411 Bishop Fionnlagh and two others were authorised by the papacy to use the income from the vacant diocese of Argyll to repair Lismore Cathedral, the seat of that bishopric.

[11] He is last known to have been alive on 25 March 1419 but was dead by 30 October when a papal mandate ordered the translation of William Stephani, Bishop of Orkney, to the now vacant see of Dunblane.
