Tigernach Ua Braín (died 1088) was abbot of Clonmacnoise and abbot of Roscommon. He was once held to be the author of the Annals of Tigernach , hence its name, but though this view is no longer sustainable, the nature and extent of his involvement remain unclear.
The annalistic compilation known as the Chronicon Scotorum mentions that he was 'heir of Ciarán and of Commán', that is abbot of Clonmacnoise and Roscommon, and came from the Síl Muiredaig,descendants of Muiredach Muillethan (d. 702), a ruling sept of the Connachta. The Uí Braín were a branch of the Síl Muiredaig, but being no player in the race for kingship, focused on Clonmacnoise to pursue a career in the church instead. The first known Uí Braín member to become abbot of Clonmacnoise was Dúnchad Ua Braín (d. 989) and others are attested after Tigernach's life-time who also headed the abbey of Roscommon. The monastery of Clonmacnoise stood in Mide, but it had held land in Connacht since the 7th century and by the 11th century it ranked as the most important church in Connacht. Since the rulers of Mide were usually in alliance with those of Connacht, Clonmacnoise appears to have remained on good terms with the rulers of both provinces.
The Annals of Ulster and the Chronicon Scotorum record Tigernach's death under the entry for 1088.
The copy of the Annals of Tigernach which is preserved in the 14th-century manuscript Oxford, Bodleian Library, MS Rawlinson B. 488, has a note attached to the entry for 1088, apparently the year of his death. It reports that Tigernach had written the text up to that point, but does not specify whether he had merely written down the text or was (also) the annalist responsible for the entries.T.M. Charles-Edwards considers it a good possibility that Tigernach was one of a succession of annalists.
Chronicon Scotorum, also known as Chronicum Scotorum, is a medieval Irish chronicle.
Donnchad mac Domnaill, called Donnchad Midi, was High King of Ireland. His father, Domnall Midi, had been the first Uí Néill High King from the south-central Clann Cholmáin based in modern County Westmeath and western County Meath, Ireland. The reigns of Domnall and his successor, Niall Frossach of the Cenél nEógain, had been relatively peaceful, but Donnchad's rule saw a return to a more expansionist policy directed against Leinster, traditional target of the Uí Néill, and also, for the first time, the great southern kingdom of Munster.
Cinioch, named Cínaed mac Luchtren in the Irish Annals, was king of the Picts, in modern Scotland, from circa 616 to 631, when his death is reported in the Annals of Ulster, the Annals of Tigernach and the Chronicon Scotorum.
The Annals of Tigernach are chronicles probably originating in Clonmacnoise, Ireland. The language is a mixture of Latin and Old and Middle Irish.

Ivar of Waterford was the Norse king of Waterford from at least 969 until his death in the year 1000, and also reigned as King of Dublin, possibly from 989 to 993, and certainly again for less than a year between 994 and 995, returning after his expulsion from the city in 993 by Sigtrygg Silkbeard, who would expel him for good the next time.

Tomrair mac Ailchi, or Thormod/Thorir Helgason, was the Viking jarl and prince who reestablished the preexisting small Norse base or settlement at Limerick as a powerful kingdom in 922 overnight when he is recorded arriving there with a huge fleet from an unknown place of departure. His ancestry is uncertain but he evidently did not belong to the Uí Ímair dynasty who only a few years before had reestablished themselves in the Kingdom of Dublin, of which Tomrair, the first King of Limerick, would immediately make himself the chief rival.
Cacht ingen Ragnaill was the queen of Donnchad mac Briain, from their marriage in 1032 to her death in 1054, when she is styled Queen of Ireland in the Irish annals of the Clonmacnoise group: the Annals of Tigernach and Chronicon Scotorum. Her husband himself, though King of Munster, is not widely regarded as having been High King of Ireland and so the extent of Cacht's influence is uncertain. That her style is superior to his presents an obviously strange situation in medieval Gaelic Ireland's male-dominated politics.
