- Sechnassach
Sechnassach mac Blathmaic (died 671) followed his father
Blathmac mac Áedo Sláine (died 665) and his uncleDiarmait mac Áedo Sláine (died 665) asHigh King of Ireland and King of Brega. He belonged to theSíl nÁedo Sláine kindred of the southernUí Néill which took its name from his grandfatherÁed Sláine (died 604). [T.M. Charles-Edwards, "Early Christian Ireland", Appendix II.]While the "
Baile Chuinn Cétchathaigh ", compiled in the reign ofFínsnechta Fledach (died 695), does not include Sechnassach or his brotherCenn Fáelad (died 675) among its High Kings, theChronicle of Ireland , on which otherIrish annals were founded, named him as a High King on his death. The omission of Sechnassach and his brother Cenn Fáelad from this king list may be deliberate as it was compiled in the reign of Cenn Fáelad's killer Fínsnechta Fledach. [T.M. Charles-Edwards, "Early Christian Ireland", p. 492.]Sechnassach's father and uncle are said to have died in a great plague—the "buide Chonaill"—which struck
Ireland from 664 or 665 onwards. ["Annals of Ulster", AU 665.1.] Sechnassach's marital alliances suggest that he had close relations with the kingdom ofLeinster . His daughter, Bé Fáil, married it's kingCellach Cualann (died 715). Sechnassach had several daughters, but no known sons.Little is recorded in the annals of Sechnassach's reign except his death. He was killed in November 671 by Dub Dúin, king of
Cenél Coirpri , a minor Uí Néill kingdom on the upper reaches of theRiver Boyne near Clonard. ["Annals of Ulster", AU 671.3.] His brother Cenn Fáelad became High King after him, probably in 672.The "Annals of the Four Masters" record of him:
Full of bridles and horsewhips, was the house in which dwelt Seachnasach,
Many were the leavings of plunder in the house in which dwelt the son of Blathmac. ["Annals of the Four Masters", M669.1.]Notes
