Claim: King of Dia Riata, Dunchad mac Conaing was co-ruler with the son of Eochaid Buide, Conall Crandomma until 654 when Conaing was killed by Talorcan.
Evidence: Dúnchad mac Conaing (or Dúnchad mac Dubáin) (died 654) was king of Dál Riata (modern western Scotland). He was joint ruler with Conall Crandomna until he was defeated and killed by Talorcan, king of the Picts, in the battle of Strath Ethairt. The Senchus fer n-Alban makes him a son of Eochaid Buide and thus a member of the Cenél nGabráin.
