Clan MacNaughton History and Origin
Share
Nestled on the rugged western coast of Scotland, where the peaks of Argyll meet deep sea lochs, lies the ancient territory of Clan MacNaughton. For centuries, the MacNaughtons stood as one of the most resilient clans in the Highlands. Their name conjures images of majestic lochside castles, fierce military loyalty, and a dramatic history marked by political survival, intense feuds, and a legendary, scandalous escape.
As a "pillar page" for genealogy researchers, history enthusiasts, and descendants, this comprehensive guide delves deep into Clan MacNaughton's past. From ancient Pictish origins to their eventual migration to Ulster, we will explore the triumphs, tragedy, and enduring symbols that define this heritage.
The Origin & Name Meaning
In Gaelic, the clan is known as Mac Neachdainn, translating to "son of Nechtan". The name Nechtan carries associations with early Scottish kingship and Pictish culture.
Linguistically, the name stems from the Celtic root nig, meaning "to wash" or "remain clean". From this came the Pictish term necht, signifying a "pledge" or "clean person" suitable as a hostage to secure peace between rival tribes. Adding the diminutive suffix -an created Nechtan ("Little Pledge"). Henry Harrison, in Surnames of the United Kingdom, notes that this distinguishes MacNaughton ("son of the little pledge") from McNaught ("son of the pledge").
Traditional genealogies trace the clan to the Pictish rulers of the Mormaer of Moray, with Nechtan Mòr ("Great Nechtan"), a powerful 10th-century chief, cited as their progenitor. Legends also connect them to King Nechtan of the Picts (early 8th century), famous for defeating Northumbrian invaders at Dunnichen (Nectansmere) in 685 and introducing Roman ecclesiastical practices at Abernethy.

The earliest written record of the clan is in a charter from around 1246. This document mentions Malcolm MacNachtan as the father of Gillechrist (Gilchrist) MacNachtan. Gillechrist granted the church of St. Mordic of Kellemurthe (Kilmorich) to the Abbey of Inchaffray. The charter declared the church was gifted "as freely as any baron of the realms of Scotland can give any church," demonstrating the high independent baronial authority of the 13th-century MacNaughtons.
Rise to Power & Key Alliances
Originally from Moray, the MacNaughtons were resettled in Strathtay and Perthshire by King Malcolm IV in the 12th century to break the power of Moray rebels. Known as the "Thanes of Loch Tay", they aligned with royal interests and helped suppress rebellions in Galloway under King Alexander II, earning further lands and establishing cadet branches like the MacNaughts of Kilquhanty and Crogo.
By the mid-13th century, under King Alexander III, three brothers—Gilchrist, Athe, and Gilbert, sons of Malcolm Macnachten—managed the transition of the clan's core focus to Argyll, establishing a defensive line on the western seaboard. On February 12, 1267, King Alexander III granted Gilchrist a royal charter appointing him heritable keeper of the castle on Fraoch Eilean in Loch Awe, securing vital control over the western waterway system.
The Wars of Independence and the Bruce
The Wars of Scottish Independence placed Clan MacNaughton in direct conflict with the Crown. Allied with their powerful kinsmen, the MacDougalls of Lorne, they initially opposed Robert the Bruce's claim to the throne.
At Dalrigh in 1306, they fought with the MacDougalls against Robert the Bruce. However, chief Donald MacNaughton was so impressed by Bruce's courage in single-handedly defending a narrow pass that he openly praised the king, defying his MacDougall allies. By 1308, they joined Bruce's forces at the Pass of Brander, and a leader recorded as "Baron Macnachten" fought at Bannockburn in 1314. Though they lost their Loch Awe lands to the Campbells, King David II compensated them with lands on Lewis.
The Tudor and Stuart Alliances
Throughout the early modern period, the MacNaughtons sought royal favor to counter the expanding hegemony of the Campbell Earls of Argyll. In 1478, Duncan Macnaghten accepted a charter from the Campbell Earls of Argyll, formally acknowledging them as feudal superiors. Sir Alexander MacNaughton, chief of the clan, was knighted by King James IV and fell alongside his sovereign at the Battle of Flodden Field in 1513.
During the 17th-century Civil War, the MacNaughtons remained staunchly loyal to the Stuarts. In 1627, Chief Alexander MacNaughton, a Gentleman of the Privy Chamber to King Charles I, raised 200 expert Highland bowmen to assist French Huguenot rebels at the Siege of La Rochelle. Legend recounts that when their transport was pursued by a French man-of-war, the Highlanders’ bagpipers and harper played so fiercely that the French were awed by the "Bagg-pypperis and marlit plaidis," allowing them to escape.
This loyalty was demonstrated again in 1650. As the Marquis of Montrose was led to his execution in Edinburgh, a MacNaughton gave him a red tartan plaid to spare him the indignity of being paraded in rags. This act of compassion is commemorated in James Drummond's 1859 painting Montrose.

In 1653, they joined Glencairn's Rising against Oliver Cromwell. John MacNaughton later led the clan in Dundee's Jacobite army, fighting at Killiecrankie in 1689. Following their defeat, John was declared a rebel and his lands forfeited. During the 1745 Rising, some clansmen fought at Culloden, while others sent Prince Charlie a fine war-charger. The servant who delivered the horse, John Macnaughton, was executed at Carlisle, famously refusing to betray his master even on the scaffold.
Feuds and the Darker History
The history of Clan MacNaughton is heavily defined by their relationship with their powerful and acquisitive neighbors, the Campbells. Over the centuries, the Campbells systematically encircled and eroded the MacNaughton territorial position. This pressure is illustrated by the actions of Christina Campbell, the widow of Alexander Macnaghten. Around 1361, seeking protection from her powerful cousin, Colin Campbell of Lochow, she surrendered one-third of the remaining MacNaughton lands to him in exchange for his political patronage and his permission to marry one of his domestic servants.
The Scandalous Fall of Dunderave
The definitive end of the MacNaughton presence at Dunderave Castle is marked by a dramatic and highly scandalous episode of deception and legal maneuvering orchestrated by the Campbells. By the late seventeenth century, John MacNaughton (the son of the former Sheriff of Argyleshire) was facing immense financial pressure from his creditors and the neighboring Campbell gentry.
John was engaged to marry the younger daughter of Sir James Campbell of Ardkinglas. However, Sir James, determined to marry off his eldest daughter Jane first, plied John with strong drink on the wedding eve. Wearing a heavy, concealing veil in the darkness, Jane substituted her younger sister. The next morning, a sober John discovered the deception.
John brought his new wife home, but when Jane was near her confinement, her younger sister came to attend to her and became pregnant. Accused of fathering the child, John was imprisoned in Inveraray on charges of incest. The younger sister organized a daring escape; the lovers slipped past guards, sailed across Loch Fyne, and fled to Ireland, marrying in Portrush. John was found guilty in absentia, and his properties were awarded to Sir James.

This triumph ended in tragedy, widely viewed as divine retribution. John’s legitimate son by Jane drowned in Loch Fyne. Sometime later, Sir James Campbell and his heir capsized in a barge near the exact spot. Sir James drowned while his son was rescued. Rumors persisted that Sir James had deliberately drowned his grandson to secure the estates, making his death seem an act of Providence.
John MacNaughton never returned to Argyll. He lived in obscurity, eventually taking a humble post as a customs collector at Anstruther in Fife under a pseudonym, where he died around 1753, ending the direct Scottish male line of the MacNaughton chiefs.
Clan Castles & Territories
To command their territories, Clan MacNaughton relied on highly defensible, strategically positioned castles that allowed them to control vital land passes and maritime trade routes in Argyll.
Fraoch Eilean Castle
In 1267, King Alexander III appointed Gilchrist MacNaughton heritable keeper of the royal castle of Fraoch Eilean ("Heathery Isle") on Loch Awe, on the condition that he maintain it and host the king when passing. Architecturally, it is a rare 13th-century hall-house, measuring 80 by 30 feet with massive walls to withstand siege. Commanding the Pass of Brander, it was crucial to western frontier defense. Today, it is a picturesque, tree-covered ruin.
Dubh Loch Castle
In the 14th century, the clan built a secondary stronghold at Lochan Dubh in Glen Shira. Positioned on a low, green promontory, it had an oval courtyard and tower. According to legend, a peddler introduced the plague here in the 16th century, killing all occupants, including an 18-year-old girl. The site was abandoned and now exists only as a turf-covered mound (70 by 50 feet) with a solitary tree.
Dunderave Castle
Following the abandonment of Dubh Loch, Chief Iain MacNaughton completed Dunderave Castle on Loch Fyne in 1596. The name derives from Dun-da-Ramh ("The Castle of Two Oars"), denoting a strategic nearby ferry crossing. An L-plan tower house with a massive circular tower, its stone lintel bears the carved inscription: "I MAN BEHALD THE END BE NOCHT VYSER NOR THE HIESTEST I HOIP IN GOD". The initials "IM" and "AN" stand for Iain MacNaughton and his wife, Ann MacLean. Restored by Sir Robert Lorimer in 1911–1912, it remains a stunning private residence.
Dundarave House (Bushmills, Northern Ireland)
Following their flight from Scotland, the chiefly family established themselves in County Antrim, Ireland, descended from Shane Dhu ("Black John") who settled there in 1580 as secretary to the Earl of Antrim. In 1846, Sir Edmund Charles Workman-Macnaghten built a new family seat in Bushmills, designed by Sir Charles Lanyon. Named Dundarave House (with an Irish 'a') to honor their lost home, this Italianate palazzo was the chiefly seat until its sale in 2014.
Symbols & Identifiers
The heraldry and visual identity of Clan MacNaughton are deeply rooted in their Highland military history and spiritual resilience:
- The Clan Motto: I Hope in God (rendered in Latin as Spero in Deo or I Hoip in God in old Scots). This declaration of faith balances the practical reality of fortified stone with spiritual trust.
- The Clan Crest: A castle tower embattled, Gules (red). This symbol was assumed by the family in honor of their appointment as heritable keepers of the royal castle of Fraoch Eilean on Loch Awe.
- The Slogan & War Cry: "Fraoch Eilean" (meaning "The Heathery Isle"), a direct reference to their first strategic stronghold on Loch Awe.
- The Plant Badge: Trailing Azalea Proper (Gaelic: Lusan Albanach / azalea procumbens). Clansmen wore this plant in their bonnets during battle as a vital means of battlefield identification.
- The Tartan: The MacNaughton tartan features vibrant red, green, black, and blue patterns. The historical "Montrose Plaid" is a notable variation associated with the clan's compassionate support of the Marquis of Montrose on his way to the gallows in 1650.
