Question: What is the date of death of Domnall Mac Donnchada Midi's father?
Sentence (from "Donnchad Midi"): The reigns of Domnall and his successor, Niall Frossach of the Cenél nEógain, had been relatively peaceful, but Donnchad's rule saw a return to a more expansionist policy directed against Leinster, traditional target of the Uí Néill, and also, for the first time, the great southern kingdom of Munster.
Relevant evidence: No
