"Although his father Alpin had been a Dalraid Scot, Kenneth had a Pictish mother and since the Pictish law of inheritance passed through the Matrilineal line, he also claimed to be the rightful representative of the Pictish line of Kings. Kenneth married the daughter of his second cousin, Constantine."
Volgens de overlevering zou hij het toenmalige Schotland in 843 hebben verenigd en zou hij de eerste koning van het Koninkrijk Schotland of Alba geweest zijn.
"Kenneth overleed op 13 februari 858 in het paleis bij Cinnbelachoir, waarschijnlijk gelegen nabij Scone. De doodsoorzaak zou een tumor zijn geweest."

"He was made King on the Moot Hill at Scone, (pronounced skoon) seated upon the famous Stone of Scone. The stone's origins are obscured by the mists of time, but it was probably brought to Argyll from Antrim by Fergus MacErc of the Dal Riata Gaels. It's Gaelic name was Lia Fail meaning the speaking stone. Scone itself was seen as the sacred centre of Pictavia."
