Eaghra Poprigh mac Saorghus

Eaghra Poprigh mac Saorghus, eponym and ancestor of the clan Ó hEaghra, King of Luighne Connacht, died 928.

Eaghra Poprigh mac Saorghus was a member of the Gailenga people of north Connacht. They were originally from the kingdom of Brega on the east coast of Ireland. Dubhaltach Mac Fhirbhisigh (665.5., pp. 654–665) gives his pedigree as:

The last name is that of Tadhg mac Cian, described at 660.6 (pp. 646–647) as the son of Cian, son of Ailill Aulom. Cian is given as the son of Sadhbh inion Conn Cétchathach (661.1, pp. 646–647). At 660.4 on the same pages is written:

Members of the family feature in the Old Irish tale, Battle of Maigh Mucruimhe, in which Cian and his six brothers were killed in the battle.

The Annals of the Four Masters, sub anno 926, state "Eaghra, son of Poprigh, lord of Luighne, in Connaught; ... died."

At 665.5 and 666.2, Mac Fhirbhisigh names his sons as Muirgheas and Maghnus. Muirgheas's descendants are given down to the brothers, Murchadh and Aodh Ua hEaghra (King of Luighne in 1155). Maghnus's descendants are brought down to Tadhg and Cian mac Tadhg mac Cormac Ó hEaghra, and their first cousins, Oilill, Brian and Cormac Óg mac Cormac Óg mac Cormac Ó hEaghra, these five men being alive in 1664.
