Origin of the Name

Moncrieff is one of Scotland's genuinely ancient families — their name and their hill form a single piece of Scottish geography that has been identified together for nearly a thousand years. Moncrieff Hill, a distinctive rounded summit rising above the Tay valley south of Perth, takes its name from the Gaelic monadh craoibhe — "the wooded hill" or "the hill of trees." The family that held and named themselves after this hill appear in Scottish records from the 12th century, making the Moncrieffs among the oldest continuously documented families in Scotland.

The family's extreme antiquity was a point of pride maintained across generations. The Moncrieffs were not a Highland clan in the typical sense — their Perthshire position placed them at the interface of Highland and Lowland Scotland, south of the Highland Line but in a county that retained deep Gaelic cultural connections. Their name, their hill, and their castle form a continuous thread in Scottish history from the medieval period to the present.

    Moncreiffe of that Ilk: The family title "Moncreiffe of that Ilk" — meaning the Moncreiffe whose family name and territorial name are the same — is one of the most ancient designations in Scottish heraldry. Sir Iain Moncreiffe of that Ilk (1919–1985), the 11th Baronet, was one of the most celebrated Scottish genealogists and heraldic authorities of the 20th century, writing extensively on Scottish clan history and serving as Albany Herald at the Court of the Lord Lyon King of Arms. His books on Scottish clans brought the subject to wide international attention in the 1960s and 1970s.
  

Territory

The Moncrieff heartland is Moncrieff Hill and the surrounding estates in southeastern Perthshire, between Perth and the Tay. The hill itself is a local landmark visible from a wide area of the Tay valley, and the estates that surrounded it — Moncrieff House, the woods, and the agricultural lands — formed the core of the family's territorial identity from the medieval period.

The position near Perth — Scotland's capital during much of the medieval period — gave the Moncrieffs proximity to the centre of Scottish political life. Perth was the site of parliaments, royal courts, and significant political events; the Moncrieffs, as a family of established local standing, were positioned to participate in national politics while maintaining their regional base.

History of the Clan

Medieval eminence

The Moncrieffs appear in Scottish royal charters from the 12th century, confirming their standing as substantial landowners in Perthshire before the Lowland Scots surname system had fully crystallised. The consistency of their presence across the medieval record — in religious donations, in charter witnesses, in service to the Crown — marks them as one of the genuinely stable Perthshire families whose history does not depend on a single dramatic moment but on sustained presence across generations.

The Baronetcy and beyond

The family was created Baronets of Nova Scotia in 1626 — one of the new titles created by King Charles I to raise money for the colonisation of Nova Scotia. The baronetcy has descended continuously, making the Moncreiffe baronets one of the longer-running Scottish hereditary lines. The 11th Baronet, Sir Iain Moncreiffe, combined heraldic expertise with a gift for popular history writing that brought the Moncreiffe name to international attention in the genealogy boom of the late 20th century.

The Moncrieff Diaspora

The Moncrieff name, while not among the high-frequency Scottish surnames in the diaspora, appears across the English-speaking world in the form of families who emigrated from Perthshire and the central Lowlands in the 18th and 19th centuries. The spelling varies — Moncrieff, Moncreiff, Moncrieffe — and researchers should check all variants.

In Australia, Gladys Moncrieff (1892–1976) — "Our Glad" — was one of the most celebrated Australian entertainers of the first half of the 20th century, a soprano and theatre actress who became a national institution. Her surname reflects the Scottish heritage that was present in many Australian families.

Variant spellings

Researchers should search Moncrieff, Moncreiff, Moncrief, and Moncrieffe — the spelling was inconsistently recorded in historical records. The 11th Baronet used the Moncreiffe spelling; branch families and emigrants may use any of the variants.
