Legends
The Macalister translation of Lebor Gabála Érenn says that Cáelbad was also King of Ulster when he killed Muiredach Tirech to take the Kingship. It also says that he took the kingship of Ireland for a space of one year, and exacted the Boroma, a cattle tax, without a battle. And he fell at the hands of Eochaid Mugmedon. Cáelbad also had a son, Fíachna Lonn mac Cóelbad, who was a King of the Dál nAraidi.

The Annals of the Four Masters, annal M356.1 says that after Muireadhach Tireach had been thirty years in the sovereignty of Ireland, he was slain by Caelbhadh, son of Crunn, King of Uladh, at Portrigh, over Dabhall. It goes on further to say in annal M357.1 that after Caelbhadh, son of Crunn Badhrai, had been one year in the sovereignty of Ireland, he was slain by Eochaidh Muighmheadhoin.
