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

Sharing is caring!

No Scottish clan has a story quite like Clan MacGregor. They were outlawed for 171 years. Their name was banned on pain of death. Their chief was hanged without trial. Yet the MacGregors survived. They hid in the Highland mist, changed their names, and passed their stories down through generations. They called themselves the Children of the Mist. Today, their descendants live across America, Canada, Australia, and New Zealand.

If your surname is MacGregor, Greig, King, Fletcher, or Greer — you may carry MacGregor blood. This is the story of your clan.

Where the Name MacGregor Comes From

MacGregor comes from the Gaelic Mac Griogair. It means “son of Griogair.” Griogair is the Gaelic form of the name Gregor. Gregor itself comes from the Latin Gregorius, which means “watchful” or “vigilant.”

The clan claims descent from a very old Celtic royal lineage. Their tradition holds that the first Gregor was a son of a 9th-century Scottish king. This royal claim is woven into everything the clan did — and everything they suffered.

The clan heartland in its earliest years was Glen Orchy, Glenstrae, and the hills north of Loch Awe in Argyll. Over the centuries, they spread east into Balquhidder and the Trossachs — the rugged landscape between Callander and Loch Lomond.

The Clan’s Bold Motto

Clan MacGregor carries one of the proudest mottos in Scotland: ‘S Rioghal Mo Dhream. In English, this means “Royal is my race.” It is not a boast. It is a statement of identity. For a clan stripped of everything, it became an act of defiance.

The clan’s battle cry was “Ard-choille!” — meaning “High wood!” This was a call back to the great Highland forests. It is a raw, ancient cry that says exactly where the MacGregors belonged.

The clan crest badge shows a crowned lion’s head. This is another symbol of their royal claim — one they held onto even when the law tried to erase them entirely.

The Battle of Glen Fruin and the Proscription

On 7 February 1603, Clan MacGregor fought the Battle of Glen Fruin near Loch Lomond. They defeated Clan Colquhoun. But they killed more than 140 men in the process.

King James VI acted swiftly. On 3 April 1603, he issued a decree through the Scottish Privy Council. The name “MacGregor” was banned. Anyone using the name faced death. Clan members could not gather in groups of more than four. They could not hold land. They could not carry arms.

Chief Allaster MacGregor of Glenstrae and 11 clan chieftains were executed in 1604. Their lands were seized. Glenstrae Castle, the ancestral seat of the chiefs, was burned in 1611.

MacGregors were forced to take other surnames. They became King, Fletcher, Comrie, Black, White, and dozens more. This is why Clan MacGregor has one of the longest sept lists of any Scottish clan. The names on that list are not just septs — they are the names of survival.

Charles II briefly lifted the proscription in 1661. King William of Orange reimposed it in 1693. It was not permanently repealed until 1774 — 171 years after it began. Those who lived through the proscription called themselves the Children of the Mist. The name stuck.

Rob Roy MacGregor – Scotland’s Most Famous Outlaw

Rob Roy MacGregor was born on 7 March 1671 at Glengyle, at the head of Loch Katrine in the Trossachs. His name in Gaelic was Rob Ruadh — Red Robert — for his distinctive red hair. In English, this became Rob Roy.

He worked as a cattle farmer and drover. He traded Highland cattle at the Crieff market. Life was hard, but it was honest.

Then disaster struck. A business partner stole a large sum of money that Rob Roy owed to the Duke of Montrose. Montrose seized Rob Roy’s lands and evicted his family. Rob Roy refused to accept this. He began raiding Montrose’s estates and stealing back his rents.

He was declared an outlaw. He evaded capture for years across the Highlands. He became a hero to ordinary Scots and a legend throughout Scotland.

Rob Roy fought in the 1689 Jacobite rising at the Battle of Killiecrankie. He was active in the 1715 Jacobite rising. He fought at Glen Shiel in 1719 alongside Spanish-backed Jacobite forces. He was eventually pardoned in 1727.

He died at Inverlochlarig on 28 December 1734. He is buried at Balquhidder Parish Church. His gravestone reads simply: “MacGregor Despite Them.”

Sir Walter Scott published his novel Rob Roy in 1817. It brought the MacGregor story to readers across the world. The 1995 film with Liam Neeson brought it to cinema audiences everywhere.

The MacGregor Tartans

Clan MacGregor has several tartans, each with its own character.

The MacGregor Red and Green tartan is the clan’s principal design. Bold red dominates the sett, crossed with green and white lines. It is one of the most striking clan tartans in Scotland. It gained wide recognition during King George IV’s 1822 visit to Edinburgh.

The Rob Roy tartan is simpler. It uses large blocks of red and black. This is one of the oldest tartan designs in Scotland. Before tartans were strictly tied to clan names, its bold simplicity made it popular across many families. It is now specifically linked to Rob Roy MacGregor.

The MacGregor Ancient tartan uses the same red and green sett but with lighter, muted tones. This style aims to recreate the look of natural plant dyes used in earlier centuries.

The MacGregor Hunting tartan uses earthy greens and browns — designed for outdoor wear in the Highland landscape.

The MacGregor Diaspora – From Scotland to the World

The Highland Clearances of the 1750s to 1880s forced thousands of Highland Scots from their land. For the MacGregors, the Clearances came after more than a century of proscription. Many families had already lost everything. Emigration was survival, not choice.

Canada saw some of the earliest Scottish settlers. MacGregor emigrants built new lives across Nova Scotia, Prince Edward Island, Cape Breton, and Ontario. The ship Hector, which landed in Nova Scotia in 1773, carried some of the first Scottish settlers to that shore.

The United States has a deep MacGregor presence. The American Clan Gregor Society was founded in 1909. MacGregors settled across the eastern seaboard, Virginia, the Carolinas, and far beyond.

Australia and New Zealand drew large numbers of Scottish emigrants from the 1820s onward. MacGregor families settled in New South Wales, Victoria, and particularly in Otago, New Zealand — a region that carries a strong Scottish heritage to this day.

The Clan Gregor Society has active chapters in North America, Canada, Australia, New Zealand, and Germany. If you want to connect with other people who share your heritage, they are a good place to start.
