Cináed mac Duib (Modern Gaelic: Coinneach mac Dhuibh) anglicised as Kenneth III, and nicknamed An Donn, "the Chief" or "the Brown", (c. 966–25 March 1005) was King of Scots from 997 to 1005. He was the son of Dub (Dub mac Maíl Coluim). Many of the Scots sources refer to him as Giric son of Kenneth son of Dub, which is taken to be an error. An alternate explanation is that Kenneth had a son, Giric, who ruled jointly with his father.
The primary sources concerning the life and "reign" of Giric include chronicle entries dating to the years 1251 and 1317. They can be found in The Chronicles of the Picts and Scots of William Forbes Skene. The chronicle of John of Fordun (14th century) mentions Giric as "Grim" or "Gryme", reporting him killed by Malcolm II of Scotland.
Kenneth III |
The only event reported in Kenneth's reign is the killing of Dúngal mac Cináeda by Gille Coemgáin mac Cináeda, by the Annals of the Four Masters s.a. 999. It is not certain that this refers to events in Scotland, and whether one or both were sons of this Kenneth, or of Kenneth II of Scotland, or some other person or persons, is not known. A "Gilla Caemgein son of Cinaed" also appears in the Annals of Ulster. An entry from the year 1035 reports that his unnamed granddaughter and her husband Cathal, son of Amalgaid, were both killed by Cellach, son of Dúnchad. This Cathal was reportedly king to the Western Laigin, possibly connected to the Kings of Leinster. The context is unclear but it is likely that this is the same Gille Coemgáin, connected to Kenneth III.
Kenneth III was killed in battle at Monzievaird in Strathearn by Malcolm II (Máel Coluim mac Cináeda) in 1005. Whether Boite mac Cináeda was a son of this Kenneth, or of Kenneth II, is uncertain, although most propose this Kenneth. A son, or grandson of Boite, was reported to be killed by Malcolm II in 1032 in the Annals of Ulster. The relevant entry has been translated as: "The grandson of Baete son of Cinaed was killed by Mael Coluim son of Cinaed."
Kenneth's granddaughter, Gruoch daughter of Boite (Gruoch ingen Boite meic Cináeda) — William Shakespeare's Lady Macbeth — was wife firstly of Gille Coemgáin, Mormaer of Moray, and secondly of King Macbeth; her son by Gille Coemgáin, Lulach (Lulach mac Gille Coemgáin), would briefly succeed Macbeth as King of Scotland. The meic Uilleim, descendants of William fitz Duncan by his first marriage, were probably descended from Kenneth; and the Clann Mac Aoidh or Clan Mackay claim descent from Kenneth III through Lulach's daughter.
Alexander III |
The status of the successive heads of this clan as the "senior inaugural official" seems confirmed by records of the inauguration ceremonies of Alexander II (reigned 1214–1249) and Alexander III (reigned 1249–1286). While earlier heads of this house "witnessed royal documents far more more frequently" than other members of the nobility. Their names often listed first among the lay witnesses, ahead of both the native Scottish nobility and the Anglo-Norman nobles. A number of 12th-century heads of house served as Justiciars of Scotia.
Their leaders were named Donnchadh (Duncan), Mael-Coluim (Malcolm), and Causantin (Constantine), names shared by the royal family. Making a close relation to the reigning royal house likely. Bannerman suggests that the MacDuffs had their own, legitimate claim to the Scottish throne. A claim which they declined to pursue, compensated with privileges by Malcolm III and his descendants.
