About Tadhg na Mainistreach Mac Carthaigh Mór

Tadhg na Mainistreach Mac Carthaigh Mór reigned as King of Desmond from 1390/2 to his death in 1428. He was the son of the previous king Domhnall Óg Mac Carthaigh Mór. According to the Annals of Inisfallen Tadhg Mac Carthaigh had the reputation as the greatest wine-drinker in Ireland when he died, but was still "a son worthy of his father". He was married to one Sebán, a daughter of "Garret the earl". This is likely a form of 'Siobhán' which translates as 'Joan,' so Sebán is probably a reference to Joan, a daughter of Gerald FitzGerald, 3rd Earl of Desmond.
