MacDonaldSurname meaning, origin and history

This report tells the story of the name MacDonald, and of McDonald and Macdonald, which are the same name wearing different centuries. It is the story of the greatest of the Highland clans: a family that ruled the western seaboard of Scotland as near-kings, lost a lordship to the Crown, suffered the most infamous massacre in Scottish history, and then carried its name onto emigrant ships bound for every English-speaking country on earth.

Clan Donald country

Clan Donald's homeland is not a glen but a coastline. For two centuries the family ruled a country measured in sea-miles: Islay and Jura at its southern gate, Mull and Ardnamurchan at its waist, Moidart and Knoydart along the mainland's ragged edge, Skye and the Uists to the north. Roads meant nothing here. The galley, the birlinn of the West Highland carvings, was the horse of this country, and every castle of the name is placed where a boat could reach it and an army could not.

Roads meant nothing here. The galley was the horse of this country.

The heart of it was Finlaggan, on a small loch on Islay. It is the most remarkable thing about the Lordship that its capital was not a fortress at all but a council place, a cluster of buildings on two islands where fourteen men of the Isles met to make law. The MacDonald lords were inaugurated there on a stone footprint, given a white rod and a sword, in a ceremony older than the Scottish crown they defied. The buildings are foundations now, in a field above a loch, and standing in them is the closest thing the name has to a national monument.

The rest of the country is castles on rock. Castle Tioram sits on a tidal island in Loch Moidart, which you can walk to at low water and be stranded on at high, and it was Clanranald's for four hundred years. Duntulm looks north from Skye's tip; Dunyvaig guards Islay's south shore; Mingary holds Ardnamurchan; Armadale is the Sleat seat and now the clan's own museum and library. And on the mainland, in Lochaber, the glen at Glencoe holds the memorial to the smallest branch of all, on the ground where the name's darkest night was spent.
