Tnúthgal mac Donngaile
Tnúthgal mac Donngaile was a supposed King of Munster from the Eóganacht Chaisil branch of the Eoganachta. He was a fifth generation descendant of Colgú mac Faílbe Flaind, a previous king.
Tnúthgal appears in some king lists but this is suspect. He is not mentioned in the Irish annals and his death date of 820 is based on the accession of Feidlimid mac Cremthanin in that year. A confusion between him and Tnúthgal mac Artrach may have occurred.
His grandsons Áilgenán mac Donngaile and Máel Gualae mac Donngaile were Kings of Munster.
