Question: Who is Eógan Mac Muiredaig's paternal grandfather?
Sentence (from "Eógan mac Muiredaig"): Presumed to be the son of Muiredach mac Ainbcellaig, and thus a king of the Cenél Loairn, Eógan is not named in any surviving Irish annals, nor does he appear in the Duan Albanach, which passes from Muiredach to Áed Find.
