  Research Notes:

The Annals of Ulster in 768 report "Bellum i Fortrinn iter Aedh & Cinaedh": a battle in Fortriu between Áed and Cináed. This is usually read as meaning Áed Find and the Pictish king Ciniod, who is called "Cinadhon" in the notice of his death in 775. The Annals of the Four Masters, a less reliable source, give a different version, placing this battle in Leinster and naming the victor as Cináed mac Flainn of the Uí Failgi and his defeated enemy as one Áed.

Áed's death in 778 is noted by the Annals of Ulster. He appears to have been followed as king by his brother Fergus mac Echdach.
