Scotland Made the Name MacGregor a Capital Offence in 1603

In 1603 the King of Scotland outlawed a surname. Using the name MacGregor became a capital offence, and it stayed illegal, on and off, for the next 171 years.

What triggered it

Clan Gregor had been feuding with the Colquhouns, who were backed by the considerably more powerful Campbells. In February 1603 the two sides met at Glen Fruin, near Loch Lomond, and the MacGregors won decisively and bloodily.

James VI responded with collective punishment aimed at the clan's identity. An edict proscribed the name itself. Every MacGregor was ordered to abandon it, and anyone who continued to use it could be executed for doing so.

Governments have exiled families, seized their land and killed their leaders throughout history. Banning the act of stating who you are is a narrower and stranger instrument, and it was designed to remove the clan from the record rather than from the country.

Living without a name

The clan scattered and borrowed. MacGregors took the surnames of neighbouring families, sometimes with those families' cooperation and sometimes without, and Murray, Grant, Stewart, Ramsay and Drummond all absorbed MacGregors during this period.

They also acquired a nickname that stuck, the Children of the Mist, which described a clan that had to keep moving and could not be pinned to a place or a name.

The most famous member of it, Rob Roy MacGregor, lived his whole life under the proscription. He spent long stretches using his mother's surname, Campbell, which given the Campbells' role in the original feud is one of the more pointed ironies in Scottish history.

Lifted, then re-imposed

The ban did not run continuously, and the popular version usually skips this part.

Charles II lifted it in 1661, in recognition of MacGregor support for the royalist cause during the civil wars. That reprieve lasted about three decades. William of Orange reimposed the proscription in 1693, after the clan backed the wrong side again during the Jacobite risings.

It was finally repealed in 1774, 171 years after Glen Fruin. By then the clan had spent the better part of two centuries operating under other people's surnames.

What happened afterwards

The name came back. When repeal arrived, families who had been carrying borrowed surnames for generations resumed MacGregor, and the clan reconstituted itself around a name that had legally not existed for most of living memory.

That recovery was possible because the proscription only ever reached the paperwork. Families knew who they were, passed it down privately, and waited. A state can control what appears on a register, and controlling what a family calls itself at home is a much harder problem.

Mongolia ran the same experiment on a national scale and got a different result. Its communist government destroyed clan names in the 1920s, and when surnames became compulsory again in 1997 most of the population could no longer remember what theirs had been. Seventy years was enough to break the chain. Scotland's MacGregors survived 171 because the ban was aimed at one clan, which could keep its own memory intact, rather than at everybody at once.
