, namely Diarmait and Blathmac, ruled in shared reigns.

All four putative successors to Domnall had been his allies at the great Battle of Mag Rath in 637, where Congal Cáech was defeated and the authority of the Uí Néill re-established, and it is not implausible that all four ruled together. He ruled from 643-654. The king lists have Cellach and Conall reigning before Diarmait and Blathmac. Both Cellach and Conall are omitted from the earliest king list—a late 7th century poem called ''Baile Chuinn''. In 650, they successfully ended a challenge to their authority in the north by defeating and killing their cousin Óengus mac Domnaill at the Battle of Dún Cremthainn. Conall Cóel was killed by Diarmait in 654 while Cellach died in 658, perhaps at Bru na Bóinne. It is possible Cellach had been captured by Diarmait in 654 and died a prisoner.Mac Niocaill, pg.98 His daughter Cacht ingen Cellaig married
