Clan MacIver, also known as Clan Iver, is Scottish clan recognised by the Lord Lyon King of Arms.[1 ] The clan, however, does not have a chief recognised by the Lord Lyon King of Arms. Because of this the clan can be considered an armigerous clan.[2 ] The clan name of MacIver is of Gaelic origin, derived from an Old Norse personal name. Various forms of the surname MacIver are considered sept names (followers or members) of several historically large Scottish clans, such as clans Campbell and Mackenzie. There exists a Clan Iver society in Fife, Scotland.
The surname MacIver is an Anglicisation of the Gaelic Mac Íomhair "meaning son of Íomhar". The Gaelic personal name Íomhar is derived from the Old Norse Ivarr.  An early man bearing the surname MacIver was Malcolm McIuyr, whose appears on a list of men in the Sheriffdom of Argyll/Lorne in 1292.[4 ]
According to Alastair Campbell of Airds, it is very unlikely that there is a common origin for one Clan MacIver. Campbell of Airds maintains that the Victorian Principal P. C. Campbell confused matters with his Account of the Clan Iver. Principal Campbell, at the time publication of his Account, was petitioning the Lord Lyon King of Arms to recognise him as "Chief of Clan Iver". Campbell was ultimately unsuccessful in his bid for chiefship. According to Campbell of Airds, the modern Clan MacIver is also a dubious a concept because it encompasses all MacIvers regardless of their origin, and that the "modern game of clan-constructing is again being played".
Campbell claimed that the MacIvers originated in Glenlyon, and settled in Argyll in 1222. The Victorian illustrator R. R. McIan considered the MacIvers to have descended from Duncan, Lord of Lochow, making them descend from the same stock as the Campbells.[1 ] According to legend, a stronghold of the MacIvers was the ancient fort of Dun Mor (Dunmore), located near Lochgilphead.[4 ]
According to Ane Accompt of the Genealogie of the Campbells, the eponymous Iver was one of two illegitimate sons of Colin Maol Math (the other illegitimate son being Tavish Coir, from whom the MacTavishes claim descent). Also, that Iver's mother was to have been a daughter of Suibhne, founder of Castle Sween, member of the kindred of Anrothan who held lands in Cowal, Glassary and Knapdale (Suibhne is claimed as the eponymous ancestor of the MacSweens).[4 ]
The leading family of the MacIver Campbells were the MacIvers of Lergachonzie and Stronshira. A branch of the MacIvers were Captains of the Castle of Inveraray, where the standing stone in the grounds of the castle was said to have been the boundary between the lands of the MacIvers and the MacVicars. Other branches of MacIver Campbells include the MacIver Campbells of Ballochyle in Cowal, the Campbells of Kirnan in Glassary, the Campbells of Pennymore on Loch Fyne, south of Inveraray, and the Campbells of Ardlarach near Ardfern, Craignish.[4 ]
Principal Campbell himself belonged to the Campbells of Quoycrook in Caithness. They were claimed to have descended from MacIvers of Lergachonzie. Campbell also claimed that the related families to this branch were the Campbells of Duchernan, the Campbells of Thurso and Lochend, and the Iverachs of Wideford in Orkney. Campbell of Airds notes that both the arms of the Iverachs and the Campbells of Duchernan display the gyronny prevalent in Campbell heraldry.[1 ]
In June, 1564, at Dunoon, in an agreement between Iver MacIver of Lergachonzie, and Archibald Campbell, 5th Earl of Argyll, the earl renounced all calps from those of the name MacIver, in return for a sum of money, though the Earl reserved the calp of Iver MacIver and his successors. According to Campbell of Airds, it would seem that dating from this agreement many MacIvers began using the name Campbell or MacIver-Campbell.[4 ]
According to the traditions of the Mackenzies, a clan of Macivers were located in Wester Ross, across The Minch from Lewis. George Mackenzie, 1st Earl of Cromartie mentioned this family in his dubious 'history of the Mackenzies'. He claimed that the 'MacIvors', 'MacAulas', 'MacBollans', and 'Clan Tarlich' were the ancient inhabitants of Kintail, and were all descended from Norwegian families.
The Wester Ross Macivers have also been connected to the Battle of Bealach nam Broig (battle of "the pass of the brogue"), fought between various north-western highland clans from the lands of Ross, against the followers of the Earl of Ross. Today the date of the battle is generally given at about 1452. Robert Gordon of Gordonstoun, writing in the early 17th century, stated that the Ross clans consisted of "Clan-juer", "Clantalvigh", and "Clan-leajwe". The 19th century historian F W L Thomas translated these as "Clan-iver", "Clan-t-aluigh, i.e., Clan-Aulay", and "Clan-leaive, i.e., Clan-Leay". According to Gordon, a force of Munros and Dingwalls overtook the mentioned clans and fought them at "Bealligh-ne-Broig", between Ferrin-Donald and Loch Broom. Gordon stated that "Clan-Iver", "Clantalvich" and "Clan Laive" were "utterlie extinguished and slain".
The early 20th century historian William C Mackenzie noted that The Highlands of Scotland in 1750 stated that "the most common inhabitants of Lewis are Morrisons, McAulays and McKivers, but when they go from home, all who live under Seaforth call themselves Mackenzies". Mackenzie considered that the majority of the Lewis Macivers seemed to have settled on the island with the arrival of the Mackenzies. The Mackenzies took control of Lewis in the early 16th century.
As tenants of the Earl of Seaforth, the inhabitants of Lewis followed Clan Mackenzie. William Mackenzie, 5th Earl of Seaforth decided to support the Jacobites forces in the 1715 Jacobite Rebellion. Mackenzie stated that Seaforth drew up a list of officers to command his troops. Seaforth's list of officers contained 16 Lewismen: four captains, four lieutenants, and four ensigns. Of these, two were MacIvers: [Lieutenant] Kenneth Maciver, Bragar; and [Ensign] S. Maciver, Callernish.
Modern Scottish clan members can show their allegiance to their clan and chief by wearing a Scottish crest badge. These heraldic badges usually display the clan chief's heraldic crest and motto surrounded by a strap and buckle. Such crest badges have been used since the Victorian era. The crest badge used by members of Clan MacIver contains the Latin motto numquam obliviscar ("i will never forget") and the heraldic crest of a boar's head couped Or. Both the crest and motto are very similar to the crest and motto of the chief of Clan Campbell—the Duke of Argyll. The motto on the MacIver crest badge actually answers that of the Campbell's chief.
