In the Life of Munnu of Taghmon ( 635 AD), it would appear that he controlled the area of Leighlin at the time of the synod over the ordering of Easter (630 AD). It is stated that Munnu, as a result of being insulted by Suibne, prophesised that his head would be cut off by his brother’s son (Cind Faílad?) and would be thrown into the Barrow, near the Blathach stream (Madlin River?). His brother Faílbe married Eithne daughter of Crundmael mac Rónáin ( 656 AD) king of Uí Cheinnselaig and Lagen Desgabair (South Leinster) and Mugain, the daughter of Faílbe, married Cellaig Cualand, King of Leinster ( 715 AD) from whom are the Uí Cellaig Cualand. There is an entry in the Annals of Ulster recording the death in 766 AD Cernach son of Flann who is also thought to be of this line.[2] Sources ↑ T. M.
