The eldest branch of the Mackays was that of the Clan-Abrach, descended from John Aberigh Mackay, second son of Angus Dubh, who received the lands of Auchness, Breachat, and others, from his brother, Neill Wasse. Of this family was Robert Mackay, writer, Thurso, historian of the clan Mackay. According to this gentleman, John Aberigh, the first of this branch, gave his name to the district of Strathnaver. In the Gaelic language, he says, the inhabitants of Strathnaver are called Naverigh, and that tribe the Sliochd-nan-Aberigh. John, their founder, some say, took his appellation of Aberigh from Lochaber, where he resided in his youth with some relatives, and from Strath-na-Aberich the transition is natural to Strath-n’-Averich. Neill Naverich, above mentioned, was so called from his having belonged to the Reay Country, that is, Strathnaver. The Clan-Abrach were the most numerous and powerful branch of the Mackays. They acted as wardens of their country, and never betrayed their trust.
The Bighouse branch were descendants of William Mackay of Far, younger half-brother of Donald Mackay of Scourie, by his second wife, Christian Sinclair, daughter of the laird of Dun.
The Strathy branch sprung from John Mackay of Dilred and Strathy, brother of the first Lord Reay, and son of Hugh Mackay of Far, by his wife, Lady Jane Gordon, eldest daughter of Alexander, Earl of Sutherland.
The Melness branch came from the Hon. Colonel Æneas Mackay, second son of the first Lord Reay, by his first wife, the Hon. Barbara Mackenzie, daughter of Lord Kintail.
The Kinloch branch descended from the Hon. Captain William Mackay, and the Sandwood branch from the Hon. Charles Mackay, sons of the first Lord Reay by his last wife, Marjory Sinclair, daughter of Francis Sinclair of Stircoke.
The founder of the Holland branch of the Mackays, General Hugh Mackay, prior to 1680, when a colonel in the Dutch service, and having no prospect of leaving Holland, wrote for some of his near relatives to go over and settle in that country. Amongst those were his brother, James, and his nephews, Æneas and Robert, sons of the first Lord Reay. The former he took into his own regiment, in which, in a few years, he became lieutenant-colonel. The latter he sent to school at Utrecht for a short time, and afterwards obtained commissions for them in his own regiment. In the beginning of 1687, several British officers in the Dutch service were recalled to England by King James, and amongst others was Æneas Mackay, then a captain. On his arrival in London, the King made him some favourable propositions to enter his service, which he declined, and, in consequence, when he reached Scotland, he was ordered to be apprehended as a spy. He had been imprisoned nearly seven months in Edinburgh Castle, when the Prince of Orange landed at Torbay, and he was liberated upon granting his personal bond to appear before the privy council when called upon, under a penalty of £500 sterling. The Dutch Mackays married among the nobility of Holland, and one of the families of that branch held the title of baron.
MACNICOL.
In a district mostly in Ross-shire, anciently known by the name of Ness, there was originally located a small and broken clan, known as the Macnicols. The only districts, according to Skene, which at all answers to the description of Ness, are those of Assynt, Edderachylis, and Duirness.
The Macnicols were descended from one Mackrycul (the letter r in the Gaelic being invariably pronounced like n), who, tradition says, as a reward for having rescued from some Scandinavians a great quantity of cattle carried off from Sutherland, received from one of the ancient thanes of that province, the district of Assynt, then a forest belonging to them. This Mackrycul held that part of the coast of Cogeach, which is called Ullapool. In the MS. of 1450, the descent of the clan Nicail is traced in a direct line from a certain Gregall, plainly the Krycul here mentioned, who is supposed to have lived in the twelfth century. He is said to have been the ancestor, besides the Macnicols, of the Nicols and the Nicholsons. When Gregall lived, Sutherland was occupied by Gaelic tribes, and the Macnicols may therefore be considered of Gaelic origin.
About the beginning of the 14th century, the family of the chief ended in an heiress, who married Torquil Macleod, a younger son of Macleod of Lewis. Macleod obtained a crown charter of the district of Assynt and other lands in Wester Ross, which had been the property of the Macnicols. That sept subsequently removed to the Isle of Skye, and the residence of their head or chief was at Scoirebreac, on the margin of the loch near Portree.
