Johnston is a place-name surname: the family took their name from a settlement called John's toun (town) in Annandale, in what is now Dumfriesshire in the Scottish Borders. The personal name John — from Hebrew Yochanan, "God is gracious" — combined with the Old English tun (estate, settlement) to create the place-name that became the family's identity.
The spelling Johnston is the Scottish form; Johnstone (with a final e) is also common and essentially equivalent. Both forms appear in historical records for the same family. The American and Canadian spelling is often Johnson — a pure patronymic that runs parallel to but is distinct from the Scottish Johnston tradition.
Annandale — the valley of the River Annan running from the Borders hills to the Solway Firth — was Johnston clan country. It is a broad, open valley in the western Borders, cattle-grazing country with a long tradition of raiding, reiving, and warfare with both English neighbors across the Border and rival Scots clans in the same region.
The most notable of the Border conflicts was the running warfare between the Johnstons and the Maxwells. For much of the 16th and early 17th centuries, these two Dumfriesshire families fought a blood feud that left both devastated. The feud's climax came at the Battle of Dryfe Sands in 1593, where the Johnstons inflicted a catastrophic defeat on the Maxwells, killing the Maxwell chief.
The Johnstons were among the most powerful Border families — the great riding clans of the Borders who were renowned as livestock reivers (raiders) in the era before the Union of the Crowns brought effective government to the frontier zone. The Borders reivers — whose raids across the English-Scottish border created the English word "bereaved" (originally: to be robbed) — included the Johnstons, Maxwells, Armstrongs, Elliots, and Scotts as major families.
The Union of the Crowns in 1603 began the suppression of the Borders reiving culture. James VI, who became James I of England, moved aggressively to pacify the Borders and end the raiding that had characterized the region for three centuries. Many Border clan families, including Johnstons, were transported to Ireland as part of the Ulster Plantation — taking their surnames into the Ulster Scots tradition.
Johnston and Johnstone are common in Ulster, brought by the Borders Scots who settled in Antrim and Down in the early 17th century. From Ulster, many Johnstons emigrated to colonial America — particularly to Pennsylvania and the Appalachian frontier — as part of the Scots-Irish migration of the 18th century.
Andrew Johnson (Johnston), 17th President of the United States, was of Scots-Irish heritage — his family's surname connection to the Johnston Border tradition illustrates how the name traveled from Annandale to American political history.
