If your family carries the name MacKay — or one of its many related surnames — your roots may lead to the far north of Scotland. The Scottish surnames of Clan MacKay stretch from Bain and Polson to Morgan and Neilson. This is one of Scotland’s great Highland clans. Their story spans fierce battles, devastating clearances, and centuries of life on the wild coast of Sutherland.
Who Were Clan MacKay?
Clan MacKay is one of the largest Highland clans in Scotland. Their ancestral home was Strathnaver, a long, beautiful valley in the far north of Sutherland. By the 14th century, their lands ran from Cape Wrath along the north coast into Caithness. This vast territory became known as Reay Country.
The clan’s first recorded chief was Iye MacKay, born around 1210. He was a descendant of Malcolm MacHeth, 1st Earl of Ross. The MacHeth family fled north in the 1160s after a conflict with King Malcolm IV. They settled in Strathnaver, and from there the MacKay clan grew in power across the far north of Scotland.
The Meaning Behind the MacKay Name
The name MacKay comes from the Gaelic Mac Aoidh, meaning “son of Aodh.” Aodh is an ancient Gaelic name that translates as “fire.” So MacKay means “son of fire” — a fitting name for a clan known for their fierce loyalty and fighting spirit. For women in the clan, the Gaelic form was Nic Aoidh, meaning “daughter of fire.”
The name appears in many forms across Scotland. You may see it written as McKay, MacCay, MacKee, or simply Kay. The clan motto is Manu Forti, which means “With a strong hand.” It sums up the character of a clan who held their remote northern lands against great odds for centuries.

Few Scottish clans held land as remote as Clan MacKay. Their territory covered the parishes of Farr, Tongue, Durness, and Eddrachillis in Sutherland. These are wild, rugged places on the very edge of the British mainland. In the 17th century, Lord Reay extended the clan’s reach east into west Caithness as well.
The clan chief’s seat was at Tongue, on the eastern shore of the Kyle of Tongue. Castle Varrich, a medieval tower, stood on a rocky promontory nearby as the ancient stronghold of the chiefs. The House of Tongue was built later as the seat of the Lords Reay. Today, the 15th Lord Reay lives in the Netherlands, but the pull of these northern lands remains strong for MacKays around the world.
The MacKay Tartans
Clan MacKay tartans are based around a rich pattern of dark green, blue-black, and navy. The Highland Society of London recorded the main sett in 1816. It has the look of the far north — sombre, strong, and deeply rooted in history.
The Ancient MacKay tartan uses softer colours that reflect the natural plant dyes used before 1860. Blues are lighter, and the greens have a mossy tone. The Modern MacKay uses brighter chemical dyes, with bottle green and deep navy as the dominant colours. A Dress MacKay also exists for formal occasions. All versions are widely available from Scottish tartan weavers and clan suppliers.

Clan MacKay at War
Clan MacKay had a long and proud military history. At the Battle of Flodden in 1513, the MacKay chief led his men south to fight for King James IV. They suffered heavy losses alongside thousands of other Scots on that tragic day.
Their greatest military chapter came in the Thirty Years War. In 1626, Sir Donald MacKay raised 3,600 Highland soldiers at Cromarty. He led them to Europe to fight for Christian IV of Denmark, then under Gustavus Adolphus of Sweden. Charles I created him Baron Reay of Reay in 1628. MacKay’s Regiment of Foote served across northern Europe for nearly a decade.
At the Battle of Killiecrankie in 1689, General Hugh Mackay of Scourie led Williamite forces against the Jacobite army. His side lost the battle that day. But his campaign ultimately secured Scotland for William III. Hugh Mackay remains one of the most noted military figures the clan produced.

The Strathnaver Clearances: A Dark Chapter
The Highland Clearances left deep wounds across Scotland. Clan MacKay’s heartland — Strathnaver — was one of the worst-hit areas. In December 1813, tenants received eviction notices. They had only months to leave homes their families had worked for generations.
In June 1814, Patrick Sellar, a factor for the Marquis of Stafford, led clearing operations across the valley. He gave families little time to remove their belongings. During one eviction, workers set fire to the home of William Chisholm while his elderly mother-in-law, Margaret MacKay, was still inside. They pulled her out. She died five days later.
Sellar faced trial in 1816 on charges of fire-raising and culpable homicide. The jury acquitted him. The clearances continued into the 1820s, with even larger removals replacing communities with sheep farms. The evictions pushed thousands of MacKay families to the coast or abroad.
Many went to Nova Scotia in Canada. The Pictou area holds a strong MacKay heritage to this day. Others went to Australia and New Zealand. You can trace many of these families through emigration records that survive in Scottish and Canadian archives. To learn more about how the Clearances affected other northern clans, read our articles on Clan Sutherland and Clan Gunn.
Where to Visit MacKay Clan Lands Today
The far north of Scotland is one of the country’s most dramatic and least-visited regions. If you have MacKay roots, these places carry real meaning.
Strathnaver Museum, Bettyhill is the heart of MacKay heritage. The museum tells the story of the Clearances and the lives of those who lived in Strathnaver across 8,000 years. It reopened in April 2023 after a £2 million refurbishment. It holds clan memorabilia, agricultural tools, Bronze Age artefacts, and detailed Clearances records. It opens Monday to Saturday from April to October, 10am to 5pm.
Castle Varrich stands on a rocky hill above the village of Tongue. A footpath leads up from the village and takes around 20 to 30 minutes to walk. Iron stairs inside give access to the top, where you get sweeping views of Ben Loyal and the Kyle of Tongue. It is free to visit and open all year.
The Kyle of Tongue is one of Scotland’s most beautiful sea lochs. The village of Tongue sits on its eastern shore. The whole area feels remote and ancient — exactly as it would have seemed to the MacKay chiefs who ruled here for centuries. The North Coast 500 road passes right through MacKay country, making it easy to include on a longer Highland road trip.
