Caintigern (died 734),[1] or Saint Kentigerna, was a daughter of Cellach Cualann, King of Leinster.[2] Her feast is listed in the Aberdeen Breviary for 7 January, and this is also her feast day in the Eastern Orthodox Church.[3]
Her husband is said to have been Feriacus regulus of Monchestre, who possibly is the same person as Feradach, grandson of Artúr of Dál Riata.[2]
Along with her brother St. Comgán and her son St. Fillan (Fáelán), the widowed Caintigern is said to have lived as a hermit, first in Strath Fillan, then in the Lennox, on the island of Inchcailloch on Loch Lomond.[2][1]
