Congallus I (DNB00)
CONGALLUS I, CONALL, son of Domangart, son of Fergus Mor Mac Earc, king of the Scots of Dalriada (511–535?), according to the chronology of Father Innes and Mr. Skene, was the third king of this race who ruled in Argyll and the Isles, but is reckoned as the forty-fourth according to the fictitious chronology of the older historians, Fordun, Boece, and Buchanan, who date the origin of this kingdom from Fergus I, son of Ferchand, in the fourth century B.C.
