Christian feast day: Baithéne mac Brénaind

Baithéne mac Brénaind was an Irish monk, one of Saint Columba's followers who accompanied him to Scotland around 563, and was the first successor as Abbot of Iona Abbey. The Annals of Tigernach record his birth in 534, and his death was likely between 596 and 598 according also to the Annals of Ulster. Irish genealogical records indicate him to be the "son of Brendan, son of Fergus, son of Conall Gulban, son of Niall Noígiallach", thus being a member of the Cenél Conaill branch of the Northern Uí Néill, as the abbots of Iona Abbey following the death of Columba often were.

June 9 is the 160th day of the year in the Gregorian calendar; 205 days remain until the end of the year.
