Aedh mac Ruaidhrí, co n-erbailt de./A hosting by Ruaidri Ua Conchobair with the Connachtmen and a battalion of Thomond to Athlone. The men of Teffa (Tethbae) delivered battle to them at the ford, and the crown prince of Connacht, Aed, son of Ruaidri, received a blow there, of which he died.
A more detailed account is given towards the end of the same year, which states that Aed was killed by a single shot of a stone, on the wicker-work of the bridge of Athlone by a lad of the men of Teffa.
There are two, possibly three, sons of Ruaidri, known to have been called Aed or Aedh:
- Aed, Crown Prince, killed 1159.
- King Aedh mac Ruaidri Ó Conchobair, died 1233.
- Aedh Muimhnech, whose son, Conchobair, was alive in 1236.
Aedh Muimhneach may be identical with Crown Prince Aed, or yet another son.
