Between roughly 1750 and 1940, approximately two million people left Scotland for new lives in North America, Australasia, South Africa, South America, and elsewhere. This was one of the largest emigrations, relative to population, that any country in Europe experienced. The causes were various, the Highland Clearances, the collapse of kelp and herring industries, the potato famine of 1846–1850, the pull of economic opportunity overseas, and the push of poverty at home. The result was the creation of a global Scottish diaspora that has shaped the cultures of Canada, the United States, Australia, New Zealand, and many other countries in ways that are still visible and still celebrated today.
Understanding Scottish emigration history is essential for anyone tracing Scottish ancestry, because the majority of people with Scottish roots outside Scotland are the descendants of emigrants, not of people who stayed. The story of why your ancestor left, where they went, and what records their journey created is the story of the Scottish emigration. This guide covers the major periods and causes of Scottish emigration, the key destinations, and the genealogical records that can help you trace your emigrant ancestor's journey. For the complete guide to Scottish genealogical research, see our article on tracing your Scottish roots.
The Highland Clearances: Scotland's Great Trauma
The Highland Clearances were the systematic removal of tenant farmers and their families from the land they had occupied for generations, carried out by landlords who found that sheep were more profitable tenants than people. They began in earnest in the late 18th century and continued through much of the 19th, reaching their most intensive phase in the decades between 1780 and 1860. In Sutherland, Argyll, Skye, Lewis, and across much of the western and northern Highlands, entire communities were evicted, their houses burned, their cattle driven off, and given a stark choice: emigrate or starve.
The clearances were not the work of anonymous economic forces, they were carried out by named landlords and their factors (estate managers) acting on explicit economic calculations. The Duke of Sutherland cleared approximately 15,000 people from inland Sutherland between 1811 and 1820, resettling them on coastal strips where they were supposed to make a living from fishing (a skill most did not have) while the inland glens were turned over to Cheviot sheep. The MacDonalds of Glengarry cleared their ancestral territory in the early 19th century. The MacLeod estates on Skye cleared extensively in the 1840s and 1850s, particularly after the potato famine.
The human cost was devastating. Communities that had occupied the same land for centuries were uprooted in a matter of months. The Gaelic language, the oral tradition, the complex web of kinship and community that had defined Highland life, all were disrupted or destroyed. The cultural trauma of the Clearances has never fully healed; it remains the defining wound in the relationship between Highlanders and their landlords, and between Highland Scotland and the wider British establishment.
For genealogists, the Clearances are significant because they created the emigration that scattered Highland Scottish communities across the globe. If your ancestor's surname suggests Highland Gaelic origins, MacDonald, Cameron, MacGregor, Fraser, MacKenzie, and they arrived in North America, Australia, or New Zealand in the period 1780–1880, there is a good chance they or their parents were cleared. The clearance records, estate papers, and emigration documents of this period are held by the National Records of Scotland and are increasingly available through genealogical databases.
Scotland in North America
Scottish settlement in North America began in the early colonial period, the Scots-Irish (Ulster Scots) who settled the Appalachian backcountry from the 18th century onwards are a distinct group from the Highland Scots who came later, but both contributed to the Scottish character of significant parts of American and Canadian life. The Highland Scots who settled Cape Breton Island in Nova Scotia in the late 18th and early 19th centuries created a Gaelic-speaking community that preserved Scottish language and culture long after it had faded in Scotland itself. Nova Scotia, the name means "New Scotland" in Latin, has the most concentrated Scottish-descended population outside Scotland, and Gaelic is still spoken in parts of Cape Breton.
Ontario, Prince Edward Island, New Brunswick, and British Columbia all received significant Scottish settlement. The Scottish contribution to the development of Canada was disproportionate to their numbers, eight of Canada's first twenty-three Prime Ministers were of Scottish descent, and the country's banking, railway, and trading institutions were founded largely by Scots. The Hudson's Bay Company, which governed much of western Canada before Confederation, was dominated by Highland Scots (particularly MacKenzies, MacDonalds, and Frasers) whose descendants populated the mixed-blood communities of the Canadian west.
In the United States, Scottish immigration was concentrated in the 18th and 19th centuries. The Scots-Irish settled the Appalachian highlands from Pennsylvania to Georgia, bringing with them a frontier culture that shaped the American south and west. Lowland Scots settled in New England, New York, and the Carolinas. Highland Scots arrived in the Carolinas in significant numbers before the Revolution, many fought on the Loyalist side, and some returned to Scotland or emigrated to Canada after 1783. The Scottish-American community grew throughout the 19th century, particularly in industrial cities like Pittsburgh, Detroit, and Cleveland where Scottish engineering and manufacturing expertise was in demand.
Scotland in Australasia
Scottish emigration to Australia began with the first colonial period and intensified dramatically from the 1820s onwards. The free emigration schemes of the 1830s and 1840s, which provided assisted passage to emigrants willing to work in the colonies, brought tens of thousands of Scots to New South Wales, Victoria, South Australia, and Van Diemen's Land (Tasmania). Many were Lowland farm workers and craftsmen; others were Highlanders displaced by the Clearances.
The Australian gold rushes of the 1850s brought another wave of Scottish emigration, this time driven by the prospect of rapid wealth rather than desperation. Scottish miners, merchants, and professionals arrived in significant numbers, and the Scottish character of Melbourne and other Victorian goldfield towns was remarked upon by contemporary observers. Scots had a disproportionate role in establishing the Australian squattocracy, the large-scale sheep and cattle pastoralists who occupied the interior of the continent, reflecting both their agricultural background and their willingness to take risks in an unknown landscape.
New Zealand received a particularly distinctive Scottish settlement. The Otago region of the South Island was established in 1848 as a specifically Scottish (and specifically Free Church of Scotland) settlement, with Dunedin as its centre. The Otago Settlers Association recruited emigrants from Scotland with promises of a specifically Scottish community in which Free Church values would prevail. The result was a community that maintained strong Scottish cultural traditions well into the 20th century; Dunedin still celebrates its Scottish heritage with an annual Highland Games and a strong sense of Scottish identity.
Lowland Scottish Emigration
The Highland Clearances are the most dramatic and emotionally powerful chapter in the Scottish emigration story, but Lowland Scotland also contributed significantly to the diaspora. Lowland emigration was driven by different forces: the industrialisation of agriculture in the late 18th century (which displaced agricultural workers in the same way that sheep displaced Highland clansmen, though less dramatically), economic depression, religious dissent, and the pull of economic opportunity overseas.
Lowland Scottish emigrants tended to be better educated and more skilled than many other European emigrant groups, reflecting the Scottish educational tradition that had produced high levels of literacy since the Reformation. Scottish engineers, doctors, teachers, ministers, and merchants played influential roles in the development of colonial institutions across the British Empire. The Scottish missionary tradition, exemplified by David Livingstone in Africa, extended Scottish influence into regions far beyond the major settlement areas.
Records for Researching Emigrant Ancestors
Tracing an emigrant ancestor requires research in both the country of origin (Scotland) and the country of destination. In Scotland, the key records are:
Passenger lists: Lists of emigrants on specific ships, held by the National Records of Scotland, the National Archives in Kew, and various colonial archives. Coverage is incomplete, not all voyages were recorded, but many survive from the early 19th century onwards. The ScotlandsPeople website has indexes to some emigration records.
Estate papers: The records of Highland estates include references to specific tenants who emigrated, often with their destinations. These papers are held by the National Records of Scotland and are indexed by estate. If you know which estate your ancestor's family lived on, the estate papers may identify them by name.
Poor relief records: Parish records of poor relief payments often include references to families who applied for assistance to emigrate, with their destinations.
In the destination country, immigration records, naturalisation papers, land grants, census records, and church registers all provide evidence of your ancestor's arrival and early settlement. Ancestry and Findmypast both have substantial collections of emigration and immigration records for North America and Australasia, and are often the most efficient starting point for destination-country research. Our complete guide to Scottish genealogical research covers the full range of available resources.
Clan Connections in the Diaspora
One of the most striking aspects of Scottish emigration is the degree to which clan identity survived the journey. Emigrants from the same clan territory often settled together in specific areas of their new country, creating communities that preserved clan connections and Gaelic culture for generations. The Camerons of Glengarry settled together in Ontario; the MacDonalds of South Uist settled together in Prince Edward Island; the MacLeods of Harris created distinct communities in Cape Breton. These clustered settlements meant that clan identity remained meaningful for decades after emigration, clan connections were maintained through church, community, and intermarriage even when the original Highland culture had been significantly transformed.
Today, clan societies worldwide maintain this connection. The Clan Donald Society of Canada, the Clan Fraser Society of Australia, and dozens of other organisations serve as focal points for diaspora communities who want to maintain their Scottish heritage identity. If your ancestor's emigration records point to a specific Highland community, there may well be a clan or local heritage society that has researched that community extensively and can provide both genealogical resources and human connection.
Our clan directory and Castles of the Clans book series can help you discover the specific territory, castles, and history of the clan your ancestor left behind, providing the Scottish end of the story that complements your research into where they went.
