Clan Blair
Blair is an old territorial name from Ayrshire, with a second ancient family at Balthayock in Perthshire. The sources we found name no current chief, so we list it as armigerous.
History
Blair began as a place-name, from the Gaelic blàr, a field or plain, and only later became a surname. Since the word names many localities, Blairs need not all share one ancestor. The records point mainly to two families: the Blairs of Blair in Ayrshire and the Blairs of Balthayock in Perthshire.
The Ayrshire line took its name from the estate of Blair near Dalry. Its first recorded member is William de Blair, who appears in a contract involving Irvine in 1205, in the reign of William the Lion. In 1296 the heir, Sir Bryce, was killed by the English at Ayr, and his brother David had to swear allegiance to Edward I of England, as many Scottish landowners did at the time.
In Perthshire, Patrick de Blair received a charter for the Balthayock estate from Nicholas de Erskine, lord of Kinnoul, in October 1370. The Clan Blair Society pictures the surviving keep there. In 1723 the heiress Margaret Blair married David Drummond's son, who took the name and arms of Blair of Balthayock.
The two houses argued over which was senior. Electric Scotland, quoting The Scottish Nation, says James VI decided that precedence belonged to whichever house had the oldest man at any given moment. Such a ruling left the question open, which helps explain why the name has no single, simple line of chiefs.
The Ayrshire Blairs stayed visible in Scottish affairs. John Blair received a charter from James III in January 1477. William Blair of Blair sat in the Convention of Estates in 1689 and backed King William; Viscount Dundee's men later seized him at Perth, and he died soon afterwards in the Highlands. In 1841 Captain William Fordyce Blair, Royal Navy, succeeded to the estate after his two elder brothers had died. Electric Scotland also lists Hunter Blair as a branch of the name.
Blair Atholl and its castle are easily confused with this clan, but that castle has long belonged to the Murrays, Dukes of Atholl. The Clan Blair Society says members of the family also settled in Ulster and North America, and it works today to connect Blairs and their descendants with Scottish roots. No current chief is named by the sources we checked, so the clan is treated here as armigerous.

Get the kilt
When you order a kilt, ask for the tartan by its full name — for example “Blair” — and say which colourway you want. “Modern” is dark and strong, “ancient” is lighter, “weathered” is muted. The sett is the same in each.
