Освиу
Aldfrith was born on an uncertain date to Oswiu of Northumbria and an Irish princess named Fín. Oswiu later became King of Northumbria; he died in 670 and was succeeded by his son Ecgfrith. Aldfrith was educated for a career in the church and became a scholar. However, in 685, when Ecgfrith was killed at the battle of Nechtansmere, Aldfrith was recalled to Northumbria, reportedly from the Hebridean island of Iona, and became king.
