Gartnait II
Gartnait son of Domelch (died 595) was a king of the Picts from 584-595.
The Pictish Chronicle king lists contained in the Poppleton Manuscript have Gartnait following Bridei son of Maelchon whose death "c".
584 is recorded by the Irish annals.
Gartnait's death is noted in the "Annals of Tigernachc".599 and the king lists have him succeeded by Nechtan nepos Uerb.
Some versions of the king list associate Gartnait with the foundation of the monastery of Abernethy, although other variants associate this either with Nechtan nepos Uerb or the similarly named pre-historic king Nechtan son of Erp.
John Bannerman proposed that this Gartnait was to be identified with the son of Áedán mac Gabráin found in the genealogies known as "Cethri Primchenela dail Riata" attached to the "Senchus fer n-Alban", and furthermore with the Gartnait whose kin were active on the isle of Skye during the 7th and early 8th centuries.
T. F. O'Rahilly had earlier rejected the identification of "Gartnait son of Áedán" with the eponym of the Skye kindred who is called Gartnait son of Accidán in the Irish annals.
The most recent study, by Fraser, rejects the existence of Gartnait son of Áedán outright, presuming this person to have been a genealogical fiction created in the early 8th century to bolster the ambitions of Cenél nGartnait, descendants of Gartnait son of Accidán, to rule in Kintyre.
Áedán mac Gabráin
Áedán mac Gabráin (pronounced in Old Irish) was a king of Dál Riata from c. 574 until c. 609.
The kingdom of Dál Riata was situated in modern Argyll and Bute, Scotland, and parts of County Antrim, Ireland.
Genealogies record that Áedán was a son of Gabrán mac Domangairt.
He was a contemporary of Saint Columba, and much that is recorded of his life and career comes from hagiography such as Adomnán of Iona's "Life of Saint Columba".
Áedán appears as a character in Old Irish and Middle Irish language works of prose and verse, some now lost.
The Irish annals record Áedán's campaigns against his neighbours, in Ireland, and in northern Britain, including expeditions to the Orkney Islands, the Isle of Man, and the east coast of Scotland.
As recorded by Bede, Áedán was decisively defeated by Æthelfrith of Bernicia at the Battle of Degsastan.
Áedán may have been deposed, or have abdicated, following this defeat.
His date of death is recorded by one source as 17 April 609.
