Dargart mac Finguine (died 685) was a member of the Cenél Comgaill kindred, after which Cowal in Scotland is named.
Alternatively, rather that representing an alternative name for all of Dál Riata, it has been suggested Corcu Réti was the name given to the kin group which later divided to form the Cenél nGabráin of Kintyre and the Cenél Comgaill of Cowal, thus excluding the Cenél nÓengusa of Islay and the Cenél Loairn of middle and northern Argyll.
After Eochaid Buide, between the main line and the "children of Fergus Goll" and the "children of Connad Cerr ... or the men of Fife", although modern studies make Connad Cerr a member of the Cenél Comgaill
The Cenél Comgaill are thought to have been centred in Cowal, which is plausibly derived from Comgall or Comgaill, and the isle of Bute.
