The Chisholm heartland of Strathglass is one of the great river valleys of the Scottish Highlands — a long, forested glen that runs southwest from the Beauly Firth near Inverness toward the mountains of Kintail. The River Glass flows through it, and the whole valley opens into the branching glens of Affric and Cannich — country that contains some of the finest ancient Caledonian pine forest remaining in Scotland.
Glen Affric in particular is now widely regarded as one of the most beautiful glens in Scotland, and conservation work there has restored significant areas of native woodland. The Chisholm chiefs held Erchless Castle at the head of Strathglass as their principal seat — a position that gave them control of this strategic western route from Inverness toward the Hebridean coast.
The clan held land in Strathglass from around the 14th century, having moved north from their original base in Roxburghshire. The move likely came through marriage connections or royal service, and the Chisholms quickly became the dominant power in this part of Inverness-shire. Their position between the Frasers to the north and east, and the Mackenzies to the west, required careful navigation of alliance politics throughout the clan period.
The Chisholm clan's history is inseparable from one of the Highland Clearances' most concentrated and documented episodes. Between 1801 and 1803, the then-chief's widow — known in the glen as "Young Marsali" — and later the chief himself carried out systematic evictions across the Strathglass valley to replace the Chisholm tenants with sheep.
The scale was devastating. Estimates suggest that 2,000 to 5,000 people — the majority of the glen's Gaelic-speaking population — were removed from Strathglass in this short period. The dispossessed tenants were people who had lived in this valley for generations, many of whom carried the Chisholm name or were dependants of Chisholm families. They were cleared to make room for commercial sheep farming that would generate higher rents from a single farmer than from an entire community of smallholders.
A witness to the Strathglass Clearances described the scene at the embarkation points: families with their cattle, their furniture, and their children, waiting for the boats that would take them down the Beauly Firth and ultimately to the emigrant ships. Many were elderly people who had no idea where they were going. They were going to Canada.
The emigrants from Strathglass settled primarily in Nova Scotia, Ontario, and Quebec. The concentration of Chisholm families in Cape Breton Island and Antigonish County, Nova Scotia, is directly traceable to these specific clearances. Communities that still carry Gaelic traditions in Nova Scotia today are descended in part from the people who were removed from Strathglass two centuries ago.
What makes the Strathglass Clearances particularly poignant in clan terms is that the people being removed were — in the traditional Highland sense — the chief's own people. The Highland clan system was based on mutual obligation: tenants owed military service and rent; the chief owed protection and loyalty. What happened at Strathglass was the deliberate destruction of that relationship for commercial advantage.
The clans who carried out clearances against their own people were not acting as chiefs in any traditional sense — they were acting as commercial landlords who happened to share a surname with their tenants. The gap between the ideology of the clan system and its actual operation in the 19th century is nowhere more visible than in Strathglass.
The Chisholm diaspora is concentrated more heavily in Canada than almost any other Scottish clan, due to the specific geography of the Strathglass emigrations. Nova Scotia — "New Scotland" — received the largest share, and Cape Breton Island in particular became a stronghold of Gaelic-speaking Scottish culture that persisted well into the 20th century.
Chisholm families in Cape Breton maintained Gaelic as a spoken language into living memory, and the traditions brought from Strathglass — music, oral poetry, the distinctively Highland Catholicism of the glen — were preserved there long after they had been diluted or lost in Scotland itself. The Gaelic College of Celtic Arts and Crafts at St. Ann's, Cape Breton, was founded specifically to preserve this heritage.
American Chisholms are less concentrated geographically, with families found across the eastern seaboard and South. The name appears in colonial Virginia records from the early 18th century and spread with Scots-Irish settlement westward.
Strathglass and the connected glens are accessible from Inverness via the A831. This is quieter, less-visited Highland country than the tourist routes to the north, which makes it ideal for those following an ancestral connection rather than a standard itinerary:
Strathglass, the clearances that emptied it, Glen Affric's ancient pines, and the Cape Breton communities where Chisholm Gaelic survived — this is the Scotland that Love Scotland readers follow every day. Cultural travel, clan heritage, and the living diaspora connections that make Scottish history personal.
