Fiacha Finnolach, son of Feradach Finnfechtnach, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He took power after killing his predecessor, Fíatach Finn. He ruled for fifteen, seventeen, or twenty-seven years, depending on the source consulted, after which he, and the freemen of Ireland, were killed in an uprising of aithech-tuatha or "subject peoples", led, according to the Lebor Gabála Érenn and the Annals of the Four Masters, by Elim mac Conrach, or by Cairbre Cinnchait according to Geoffrey Keating. His wife Eithne, daughter of the king of Alba (Scotland), who was pregnant, fled home to Alba, where she gave birth to Fíachu's son, Tuathal Techtmar, who would ultimately return to Ireland to claim the throne. The Lebor Gabála Érenn synchronises his reign with that of the Roman emperor Nerva (AD 96–98). The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to AD 28–55, that of the Annals of the Four Masters to AD 39–56.

Eochaid Gonnat or Gunnat ("wounding"?), son of Fiach, son of Imchad, son of Bresal, son of Sírchad, son of Fíatach Finn, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He came to the throne on the death of Cormac mac Airt. He ruled for a year, before falling in battle. Sources differ as to his killer: he was either Lugaid mac Lugna, Lugaid Menn son of Óengus, or Lugna Feirtre. He was succeeded by Cormac's son Cairbre Lifechair. The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates his reign to 244–245, the Annals of the Four Masters to 266–267.
Cairbre Lifechair, son of Cormac mac Airt, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He came to the throne after the death of Eochaid Gonnat. During his time Bresal Belach was king of Leinster, and refused to pay the bórama or cow-tribute to the High King, but Cairbre defeated him in the Battle of Dubchomar, and from then on exacted the bórama without a battle.
Fothad Cairpthech ("chariot-fighter"), and Fothad Airgthech, sons of Lugaid mac Con and Fuinche, daughter of Nár, were, according to medieval Irish legend and historical tradition, joint High Kings of Ireland. According to the poem Reicne Fothaid Canainne, there were three brothers called the Fothads, which was a nickname. The other brother was Fothad Canainne. The poem states Fothad Airgthech's real name was Oendia meaning "one god" and Fothad Cairpthech's real name was Tréndia meaning 'strong god'. However the Mongan tale below states Fothad Airgthech's first name was Eochaidh. They came to the throne after the death of Cairbre Lifechair. They ruled a year, until Fothadh Airgthech killed his brother, and was himself killed by Caílte mac Rónáin of the fianna, and the followers of Caibre's son Fiacha Sraibhtine, in the Battle of Ollarba. A dispute as to Fothad Airgthech's place of death is the subject of an Old Irish tale "Scél as-a:mberar combad hé Find mac Cumaill Mongán", the silver found in his grave is probably the reason for his last name. The chronology of Geoffrey Keating's Foras Feasa ar Éirinn dates their reign to 272–273, the Annals of the Four Masters to 284–285.
Fiacha Sraibhtine, son of Cairbre Lifechair, was, according to medieval Irish legend and historical tradition, a High King of Ireland.

Fíacha and the fianna then defeated and killed Fothad in the Battle of Ollarba.

Eithne and her sister Sodelb are two relatively obscure Irish saints from Leinster who are supposed to have flourished in the 5th century. They are commemorated together in the Irish martyrologies on 29 March, though 2 and 15 January were also marked out as feast-days. The 17th-century scholar John Colgan believed that a Life written for them had been witnessed in c. 1490 by Cathal Óg Mac Maghnusa, whom he regarded as the author of additions to the Félire Óengusso. Although nothing of the kind has come to light, they do make cameo appearances in the Lives of two better known 6/7th-century saints, Áedan and Moling, both bishops of Ferns.
