Scottish Surnames of Clan MacDonald – Origins, Tartans and Clan History

Sharing is caring!

The Scottish surnames of Clan MacDonald carry with them one of the most extraordinary legacies in Highland history. Whether your name is MacDonald, MacAlister, MacRory, or MacConnell, you may share a bloodline with the most powerful and far-reaching clan Scotland has ever known — a dynasty that once ruled the western seas, commanded the loyalty of island chiefs from the Hebrides to Ulster, and bore the grandest title in Gaelic Scotland: the Lords of the Isles. If you carry a MacDonald sept name, your roots run deep into the ancient rock of Scotland itself.

Clan Donald — to use its oldest Gaelic form — is not simply a clan. It is a confederation of families that once stretched from the Glens of Antrim in Ireland to the far reaches of the Scottish Highlands and Islands. At the height of its power, Clan MacDonald ruled more territory than many European princes. Today, millions of people across the United States, Canada, Australia, and New Zealand carry MacDonald surnames — most without realising the extraordinary story behind their name.

This guide covers the origins, meanings, and Gaelic roots of the most important Scottish surnames of Clan MacDonald, the clan’s remarkable history, its iconic tartans, and the places in Scotland where you can walk the very ground your ancestors once called home. If you’re researching your Scottish ancestry, start with our step-by-step guide to tracing your Scottish ancestry — and then come back here to learn what your name truly means.

The Origins of the Scottish Surnames of Clan MacDonald

Dòmhnall – The World Ruler at the Heart of It All

Every MacDonald surname traces its lineage to a single personal name: Dòmhnall. This ancient Gaelic name is composed of two elements — domno, meaning “world,” and val, meaning “to rule.” Dòmhnall, therefore, translates as “world ruler” — and the clan that bears this name largely lived up to the title for four centuries.

The specific Donald honoured in the clan’s name was the grandson of Somerled (or Somhairle in Gaelic), a legendary Norse-Gaelic warrior and King of the Isles who died in 1164. Somerled was himself of mixed Viking and Celtic ancestry — a fitting origin for a clan that would come to dominate the boundary between the Norse world and the Gaelic world. Donald, son of Reginald (Raghnall) and grandson of Somerled, gave his name to the dynasty: Mac Dhòmhnaill — “son of Donald.”

The Gaelic Mac Dhòmhnaill was Anglicised into MacDonald, Macdonald, and McDonald in Scotland, and MacDonnell or MacDonell in parts of Ireland and Glengarry. The “Mac” prefix simply means “son of,” making these names patronymic — identifying you as a descendant of a founding Donald.

Scottish Surnames of Clan MacDonald – Septs, Variants and Their Gaelic Origins

Clan MacDonald is the largest of all Scottish clans, encompassing dozens of branch families and sept names. A sept is a family group associated with a larger clan — often through kinship, geographic proximity, or historical alliance. Below are the most significant MacDonald surnames and what they mean:

Core MacDonald Surnames and Their Meanings

• MacDonald / Macdonald / McDonald — From Mac Dhòmhnaill, “son of Donald.” The world ruler’s children. The most common spelling in Scotland and across the diaspora. Over 165,000 people worldwide carry this surname today.
• MacDonnell / MacDonell — An Irish and Glengarry variant of MacDonald. The MacDonnells of Antrim were a powerful branch of Clan Donald who controlled the sea crossing between Scotland and Ireland. If your family came from Ulster, you may be a MacDonnell rather than a MacDonald.
• MacConnell / McConnell — Found particularly in Ulster and the Scottish diaspora. When the Gaelic Mac Dhòmhnaill is pronounced rapidly, the “dh” sound softens and disappears, giving rise to MacConnell. A phonetic cousin of MacDonald.
• MacAlister / McAlister — From Mac Alasdair, “son of Alexander.” The MacAlisters are the senior cadet branch of Clan Donald, descended from Alasdair Mòr, a son of Donald Mòr MacDonald. They established their own chief and territory in Kintyre but remain part of the broader Clan Donald family.
• MacIain / MacKean / MacKain — From Mac Iain, “son of John.” The MacDonalds of Glencoe — that most tragic of branches — were known as Clan Iain Abrach. Their chief Maclain (Old MacDonald of Glencoe) was the man killed in the Massacre of 1692. MacKean and MacKain are anglicised spellings.
• MacEachern / MacEachran — From Mac Eachainn, “son of Eachann.” Eachann means “horse lord” — a noble epithet. The MacEacherns were a sept of Clan Donald, found mainly in Argyll and Kintyre.
• MacRory / MacRuari / MacRury — From Mac Ruaraidh, “son of Ruaraidh” (Roderick or Rory). The MacRuaris were a branch of Clan Donald descended from Ruaraidh Mòr, a grandson of Somerled. They held lands in the Rough Bounds — the remote coastal territories of the western Highlands.
• MacSorley / MacSorlie — From Mac Somhairle, “son of Somerled.” Honouring the great ancestor himself. MacSorleys are found in Kintyre and the Hebrides.
• MacGorrie / Gorrie — From Mac Goraidh, “son of Godfrey” (the Norse Guðfriðr). A reminder of the Viking blood that ran through the MacDonald line. Found in the Hebrides and Argyll.
• MacMurdoch / McMurdoch — From Mac Murchaidh, “son of Murchadh.” Murchadh means “sea warrior” — entirely appropriate for a clan of island chiefs who ruled the western seas. Associated with branches in Kintyre.
• MacColl / McColl — From Mac Colla, “son of Coll.” Associated with the MacDonalds of Keppoch and Colonsay. The legendary warrior Alasdair Mac Colla (Colkitto) was a MacDonald war leader during the civil wars of the 1640s.
• MacQueen / McQueen — From Mac Suibhne, “son of Suibhne,” meaning “pleasant” or “well-going.” A sept of Clan MacDonald, though some MacQueens later associated with Clan MacKintosh. If your McQueen line comes from the Hebrides or west Highlands, MacDonald heritage is likely.
• Darroch — An old sept name associated with Clan Donald, found on the Isle of Jura. From the Gaelic doire, meaning “oak grove” — a surname rooted in the landscape rather than a personal name.
• Saunders / Alexander / Allaster — Anglicised forms connected to the MacAlister branch of Clan Donald. If your family name is Alexander or Saunders with roots in Kintyre or Argyll, you may be of MacDonald lineage.
• Hector / Ector — From Eachann, sometimes anglicised as Hector. Used as both a given name and a surname within the MacDonald family, particularly in the Hebrides.

The Lords of the Isles – Scotland’s Greatest Gaelic Dynasty

For nearly four centuries, the chiefs of Clan Donald held a title that no other family in Scotland could claim: the Lordship of the Isles. At its greatest extent in the 15th century, this was not a minor noble title but a sovereign power — controlling the Hebrides, much of the western Highlands, and vast territories in Ireland. The Lord of the Isles held his own court, conducted foreign policy, and commanded armies. The Kings of Scotland viewed the MacDonald lords with equal measures of admiration and alarm.

The Lordship of the Isles was forfeited to the Scottish Crown in 1493 — a moment of catastrophic loss for the clan that still echoes in Highland memory today. The breaking of the Lordship scattered the MacDonald branches, weakened their collective power, and set the scene for centuries of conflict, both within the clan and with their neighbours.

Clan MacDonald Tartans

With over 40 registered tartan variants, Clan MacDonald has one of the richest tartan traditions of any Scottish clan. Each pattern tells a slightly different story about the clan’s identity and heritage. If you’d like to explore how to identify and wear your clan tartan, read our guide on how to find your clan’s tartan.

MacDonald Modern Tartan

The MacDonald Modern tartan is characterised by wide bands of deep green and red, with narrow stripes of yellow, black, and white. The green represents the clan’s ancestral lands — the hills and glens of Kintyre, Islay, Skye, and the Rough Bounds. The red honours the warrior spirit that defined the clan through centuries of battle. This is the tartan most commonly worn today at Highland games and clan gatherings worldwide.

MacDonald Ancient Tartan

The Ancient MacDonald tartan uses the same sett (pattern) as the Modern but in softer, lighter tones — pale green, light blue, a hint of orange — reflecting the plant-based dyes that Highland weavers would have used before the age of synthetic colour. Wearing the Ancient tartan is a way of reaching back further in time, to the days before the Clearances and the diaspora.

MacDonald Dress Tartan

The Dress MacDonald tartan introduces white as a dominant colour — a symbol of nobility and formal occasion. Red, green, and blue remain central, but the white ground gives the tartan a brightness and elegance suited to formal Highland dress. Individual branches of the clan — MacAlister, MacDonell of Glengarry, MacDonald of Sleat, Clanranald — each have their own registered tartans as well.

The Massacre of Glencoe – A Wound That Never Healed

No history of Clan MacDonald can pass over the events of 13th February 1692. In the early hours of that morning, government soldiers — billeted with the MacDonalds of Glencoe for twelve days under the laws of Highland hospitality — turned on their hosts. Chief Maclain, 33 of his men, two women, and two children were killed. Dozens more fled into a snowstorm and died of exposure in the mountains.

The Massacre of Glencoe was not simply an act of violence. It was a deliberate act of treachery — a violation of the sacred Highland code of hospitality — ordered by the government and carried out by men who had eaten at the MacDonalds’ table. The Campbells, who led the government troops, bore the primary blame in Highland memory, cementing an enmity between the two clans that persisted for generations. (For more on the Campbells’ own complex history, read our guide to the Scottish surnames of Clan Campbell.)

The MacDonalds of Glencoe later rose again in the Jacobite Rebellions of 1715 and 1745, fighting for the Stuart cause under Bonnie Prince Charlie. The defeat at Culloden in 1746 shattered what remained of the traditional clan system, and in the years that followed, the Highland Clearances drove tens of thousands of MacDonald descendants from their ancestral lands — across the Atlantic, across the Pacific, to wherever the emigrant ships could carry them.

The MacDonald Diaspora – Carrying the Clan Name Across the World

Today, MacDonald is one of the most common Scottish surnames in the world. In Canada, the name is so prevalent that it was carried by the country’s very first Prime Minister — Sir John A. Macdonald, of Scottish Highland descent. In the United States, Australia, New Zealand, and South Africa, communities of MacDonald descendants established towns, farms, churches, and Highland societies that kept the clan’s memory alive for generations.

The migration came in waves. The first wave followed the Jacobite defeat in 1746, when Jacobite sympathisers — many of them MacDonald men — were driven into exile or emigrated under duress. The second great wave came with the Highland Clearances from the 1780s to the 1850s, when landlords cleared entire glens of their tenants to make way for sheep. MacDonalds from Skye, Kintyre, the Uists, and the mainland were loaded onto ships and landed in Nova Scotia, Prince Edward Island, Upper Canada, and Australia.

If your MacDonald line came through Nova Scotia, Cape Breton Island, or Prince Edward Island, there is a very high probability that your ancestors left directly from the Scottish Highlands and Islands between 1790 and 1850. Scottish genealogical records — particularly the Old Parish Registers and the Valuation Rolls — can often pinpoint exactly which glen your family came from. Our complete guide to tracing your Scottish ancestry walks you through every step of the research process.

Where to Walk in the Footsteps of Your MacDonald Ancestors

Scotland’s MacDonald ancestral lands are some of the most dramatic and beautiful places in the country. Whether you are tracing a specific family branch or simply honouring the broader MacDonald heritage, these are the places that matter most. If you’re planning your trip, our guide to planning a trip to Scotland from the US will help you put together a meaningful itinerary.

Glencoe – The Heart of MacDonald Sorrow

Glencoe is perhaps the most emotionally resonant place in all of Scotland. The valley itself is breathtaking — a cathedral of dark rock and ancient moraine, with Buachaille Etive Mòr standing sentinel at its entrance. But beneath the beauty lies history. The Signal Rock, where the order for the massacre was reportedly given, can still be visited. The Glencoe Folk Museum in the village tells the story with sensitivity and depth. For any MacDonald descendant, standing in Glencoe is not tourism — it is a reckoning with identity.

Armadale Castle and the Museum of the Isles, Isle of Skye

The spiritual home of Clan Donald sits on the southern tip of the Isle of Skye. Armadale Castle — now partly ruined but surrounded by extraordinary woodland gardens — was the seat of the MacDonalds of Sleat, one of the most prominent branches of the clan. The Museum of the Isles, set within the castle grounds, houses five galleries of MacDonald artefacts, Jacobite relics, and crofting history. The Clan Donald Lands Trust, which manages the estate, was formed in 1971 to preserve the last 20,000 acres of what was once a vast MacDonald domain.

Castle Tioram, Ardnamurchan Peninsula

Rising from a tidal island in Loch Moidart, Castle Tioram was a stronghold of the MacDonalds of Clanranald for centuries. The castle was deliberately burned in 1715 to prevent it falling into government hands before the Jacobite Rising. Today its ruins stand as one of Scotland’s most romantically situated castles — accessible on foot at low tide — a hauntingly beautiful monument to a family that chose honour over safety.

Islay – The Island of the Lords

Finlaggan on Islay was the seat of government for the Lords of the Isles. Here, on a small crannog in a loch, the great MacDonald chiefs held court, received ambassadors, and administered their island kingdom. The Finlaggan Heritage Centre on the island tells this story with archaeological evidence and imaginative reconstruction. If your MacDonald line is from the south Hebrides, Islay is where your ancestors’ story truly began.

Frequently Asked Questions About Scottish Surnames of Clan MacDonald

What does the surname MacDonald mean in Gaelic?

MacDonald comes from the Scottish Gaelic Mac Dhòmhnaill, meaning “son of Donald.” The personal name Dòmhnall is made up of two ancient elements: domno (world) and val (to rule), giving the full meaning of “son of the world ruler.” The clan took its name from Donald, the grandson of the Norse-Gaelic hero Somerled, Lord of the Isles.

Is McDonald the same clan as MacDonald?

Yes. McDonald and MacDonald are spelling variants of exactly the same Gaelic name — Mac Dhòmhnaill. The capitalisation of the “D” (MacDonald versus McDonald) is a modern convention. In historical records, both spellings appear interchangeably. MacConnell and MacDonnell are also variants of the same name. All are considered part of Clan Donald.

Are MacAlister, MacRory, and MacSorley part of Clan MacDonald?

Yes. These are MacDonald sept names — families associated with the broader Clan Donald through shared descent from Somerled and his grandson Donald. MacAlister (son of Alexander) is the senior cadet branch of Clan Donald. MacRory (son of Rory/Ranald) and MacSorley (son of Somerled) both trace directly to the founding Norse-Gaelic ancestors. If you carry any of these names, you may wear MacDonald tartan and claim Clan Donald heritage.

What happened to the MacDonalds of Glencoe?

The MacDonalds of Glencoe — known as Clan Iain Abrach — were massacred on 13th February 1692 by government soldiers acting on orders from King William III’s government. Thirty-eight members of the clan were killed; many more died of exposure fleeing into the winter mountains. The survivors rebuilt in Glencoe and later fought in the Jacobite risings of 1715 and 1745. Descendants of the Glencoe MacDonalds are found throughout Scotland and the Scottish diaspora today.

Where is the best place to learn about Clan MacDonald heritage in Scotland?

The Museum of the Isles at Armadale Castle on the Isle of Skye is the principal heritage centre for Clan MacDonald, managed by the Clan Donald Lands Trust. Glencoe offers deep emotional significance for the Glencoe branch of the family. Finlaggan on Islay tells the story of the Lordship of the Isles. For genealogical research, the National Records of Scotland in Edinburgh and ScotlandsPeople.gov.uk are the primary sources.

Your Ancestors Left Scotland. It’s Time to Go Back.

Millions of people across the world carry a MacDonald surname without knowing the full weight of the name they bear. You carry the legacy of the Lords of the Isles — of men and women who held court in Finlaggan, who stood their ground at Glencoe, who crossed oceans carrying nothing but their name and their will to survive. That name is your connection to one of the most extraordinary family histories Scotland has ever produced.
