Clan Armstrong: A Legacy of Border Reivers, Pele Towers and the Unvanquished Spirit
Introduction
Clan Armstrong is one of the most famous clans of the Scottish Borders, forever linked with Liddesdale, the Debatable Lands, Border reiving, Gilnockie Tower, Mangerton, and the fierce independence of the Anglo-Scottish frontier.
Unlike many Highland clans whose stories are shaped by glens, islands and chiefs in the north and west, Clan Armstrong belongs to the hard, dangerous world of the Border Marches. This was a land of cattle raids, fortified towers, shifting loyalties, family alliances and constant tension between Scotland and England.
The Armstrong motto is:
“Invictus Maneo”
“I remain unvanquished.”
It is one of the most fitting mottos in Scottish clan history. Even after royal suppression, dispersal and centuries of change, the Armstrong name survived and spread across the world. Gilnockie Tower, now closely associated with Armstrong heritage, describes the motto as “I remain unvanquished” and presents the tower as a major centre of Armstrong clan memory.
This article explores the history, people, heritage, tartan, crest, motto, Border strongholds and modern legacy of Clan Armstrong.
Chapter I: Origins of Clan Armstrong
The surname Armstrong is one of the clearest and most powerful names in Scottish clan history. It literally suggests a person of strong arm — a warrior, fighter, protector or man of great physical strength.
The Armstrong Clan Association states that the surname was first recorded in Ousby, Cumberland, in 1223, in a region that had moved between Scottish and English influence during the medieval period. The same source presents the name as ancient in the Border region and links its spirit to the clan motto “Invictus Maneo.”
The Gaelic form sometimes given for the clan is:
Clann Mac Ghillielàidir
This is generally understood as a Gaelic rendering of “son of the strong servant” or “servant of the strong one,” though Armstrong is fundamentally a Border surname rather than a purely Gaelic Highland one.
By the late medieval period, the Armstrongs had become one of the most powerful families in Liddesdale and the Scottish West March. Their world was not peaceful. It was a frontier society where survival depended on kinship, horses, towers, weapons, loyalty and reputation.
Chapter II: Clan Territory and Ancestral Lands
Clan Armstrong’s historic heartland lies in the Scottish Borders, especially:
-
Liddesdale
-
Eskdale
-
Canonbie
-
Langholm
-
Newcastleton
-
The Debatable Lands
-
Dumfriesshire
-
The Anglo-Scottish Border
The clan’s most important historic places include:
Gilnockie Tower
Mangerton Tower
Gilnockie Tower, near Canonbie, is strongly associated with the Armstrongs and is now home to a major Armstrong heritage centre. It stands in the old Border country, close to the English line, in the landscape once known for reivers, raids and fortified pele towers.
The Debatable Lands were among the most lawless and contested territories in Britain. Neither Scotland nor England could easily control them. Families such as the Armstrongs, Elliots, Grahams, Nixons and Croziers lived in a world where official authority was often distant and survival depended on armed kin networks.
To understand Clan Armstrong, one must understand the Border world: not romantic Highland mist, but hard frontier country, where men rode by night, towers were built for defence, and family names could become feared across both kingdoms.
Chapter III: Important People of Clan Armstrong
Johnnie Armstrong of Gilnockie
The most famous figure in Clan Armstrong history is Johnnie Armstrong of Gilnockie, one of the legendary Border reivers.
Johnnie Armstrong was associated with Gilnockie Tower and became known as a powerful and feared Border figure. Scotland Starts Here describes Gilnockie Tower as the residence of Johnnie Armstrong around 500 years ago, and notes that in 1530 the Scottish king ordered his hanging.
His death became one of the great tragedies of Border memory. In later tradition, Johnnie Armstrong was not remembered simply as a criminal, but as a charismatic Border chief whose power threatened royal authority.
Archibald Armstrong of Mangerton
Archibald Armstrong of Mangerton is remembered as the last known chief of Clan Armstrong. Clan reference material identifies him as the last chief and records his death in 1610, during the period when the Crown was brutally pacifying the Borders after the Union of the Crowns.
His fate symbolises the end of the Armstrongs as an independent Border power.
Kinmont Willie Armstrong
Kinmont Willie Armstrong is another famous Armstrong reiver, remembered for one of the most daring rescue stories in Border history. His capture and rescue from Carlisle Castle became part of the heroic folklore of the Marches.
Although the Armstrongs were often branded lawless by royal authorities, figures such as Kinmont Willie show why the reivers remained powerful in memory: they represented courage, loyalty and defiance in a brutal frontier world.
Neil Armstrong
One of the most famous modern bearers of the name was Neil Armstrong, the first human being to walk on the Moon. Clan sources often note his connection to the Armstrong name and tartan heritage. Discover Britain records that Neil Armstrong visited Gilnockie after being made Freeman of Langholm.
This gives Clan Armstrong a remarkable historical arc: from Border towers and reiving horses to the surface of the Moon.
Chapter IV: Castles, Strongholds and Historic Sites
Gilnockie Tower
Gilnockie Tower, also known as Hollows Tower, is the most famous Armstrong stronghold.
It stands near Canonbie in Dumfriesshire and is closely associated with Johnnie Armstrong of Gilnockie. The tower is now an important Armstrong heritage centre and is promoted as the ancestral home of the Armstrong Clan.
A pele tower like Gilnockie was not built for luxury. It was built for survival. Thick walls, narrow entrances and defensible upper floors made these towers essential in the violent Border country.
Mangerton Tower
Mangerton Tower, near Newcastleton, was another major Armstrong site. It was associated with the Armstrongs of Mangerton, the chiefly line of the clan. Clan reference sources list Mangerton as the historic seat of Clan Armstrong.
Although much of the old tower is now ruinous, the name remains central to Armstrong identity.
Hermitage Castle
Hermitage Castle is not an Armstrong seat in the same way as Gilnockie or Mangerton, but it is important to Armstrong history. Discover Britain notes that the second chief, Alexander Armstrong of Mangerton, was killed at Hermitage Castle.
Hermitage Castle itself is one of the darkest and most formidable fortresses in the Borders, long associated with violence, power and frontier lordship.
The Debatable Lands
The greatest Armstrong “stronghold” was the Border landscape itself: Liddesdale, Eskdale and the Debatable Lands. This was the clan’s arena of power, danger and survival.
Chapter V: Battles, Wars and Clan Events
Clan Armstrong’s history is inseparable from the world of the Border Reivers.
The Border Reiver Era
For around 300 years, from the late 13th century into the early 17th century, the Anglo-Scottish Border was repeatedly destabilised by war, raiding and weak central authority. The Armstrong Clan Association describes the Border region during this period as a front-line “war zone,” where families such as the Armstrongs lived amid constant conflict.
The Armstrongs became one of the most powerful reiving families of the West March. They raided cattle, defended kin, built towers and formed alliances with other Border surnames.
To outsiders, they were lawless raiders.
To their own people, they were protectors, horsemen and survivors.
The Execution of Johnnie Armstrong — 1530
One of the defining moments in Armstrong history came in 1530, when Johnnie Armstrong of Gilnockie was executed on the orders of King James V of Scotland. Scotland Starts Here records that Johnnie Armstrong was hanged in 1530 and later romanticised in Border literature and tradition.
This event became a symbol of the clash between royal authority and Border independence.
The Union of the Crowns — 1603
In 1603, James VI of Scotland became James I of England. The Union of the Crowns transformed the Border. What had once been a frontier between two kingdoms now became an internal problem for one monarch.
The Crown no longer tolerated the semi-independent power of the reiver families. The Armstrongs, like many Border surnames, were suppressed, executed, transported, forced to migrate or scattered into Ulster and beyond.
The Death of Archibald Armstrong — 1610
The death of Archibald Armstrong of Mangerton in 1610 symbolised the destruction of the old Armstrong power structure. Clan reference material identifies him as the last chief and links the dispersal of the clan to the Crown’s pacification of the Borders.
This was the end of the Armstrongs as a major independent Border force — but not the end of the name.
Chapter VI: Clan Crest, Motto and Badge
Clan Crest
The Armstrong crest is commonly described as:
An arm from the shoulder, armed, proper
This is a perfect heraldic expression of the name itself: Armstrong — the strong arm.
It is bold, direct and martial. It symbolises strength, defence, courage and readiness.
Clan Motto
The clan motto is:
“Invictus Maneo”
This means:
“I remain unvanquished.”
The motto is widely associated with Clan Armstrong and is used by Armstrong heritage bodies and Gilnockie Tower.
Few clan mottos fit their history so well. The Armstrongs were suppressed, scattered and stripped of chiefly power, yet the name endured.
They remained unvanquished.
Clan Badge
A clearly established plant badge for Clan Armstrong is not as consistently recorded as for some Highland clans.
For accuracy, the safest symbols to emphasise are:
-
The armed arm crest
-
The motto “Invictus Maneo”
-
Gilnockie Tower
-
Mangerton
-
The Armstrong tartan
-
The reiver horseman tradition
This is appropriate for a Border clan, where towers, arms, horses and kinship mattered more than the plant badges often associated with Highland clan gatherings.
Chapter VII: Clan Tartans
Clan Armstrong has an officially recorded tartan.
Armstrong Tartan
The Armstrong tartan is listed by the Scottish Register of Tartans. The register records the Armstrong tartan under reference 115.
ScotlandShop describes the Armstrong tartan as mostly green and navy, with red and black lines, and notes that both modern and ancient variations are used.
Armstrong Ancient Tartan
The ancient version of the Armstrong tartan is often associated with softer, lighter shades, while the modern tartan usually appears darker and stronger in tone.
For modern Armstrong descendants, the tartan represents:
-
Border reiver ancestry
-
Liddesdale and the Debatable Lands
-
Gilnockie Tower
-
Mangerton
-
The motto “Invictus Maneo”
-
Family survival after dispersal
-
Scottish Border identity
The Armstrong tartan is not merely decorative. It is a visual link to one of Scotland’s most dramatic Border names.
Chapter VIII: Heritage, Identity and Clan Traditions
Clan Armstrong represents one of Scotland’s great Border identities.
Its story includes:
-
The Scottish Borders
-
Liddesdale and Eskdale
-
The Debatable Lands
-
Border reiving
-
Gilnockie Tower
-
Mangerton Tower
-
Johnnie Armstrong of Gilnockie
-
Kinmont Willie Armstrong
-
The motto “Invictus Maneo”
-
The armed arm crest

-
Migration to Ulster and the wider world
Associated names and spellings include:
-
Armstrong
-
Armstrang
-
Armstang
-
Armestrang
-
Armystrang
-
Strongarm
The Armstrong identity is not soft or ornamental. It is a name forged in the frontier zone between two kingdoms.
It speaks of strength, danger, survival and defiance.
Chapter IX: Clan Armstrong Today
Today, Clan Armstrong is generally described as an armigerous clan, meaning it has no currently recognised chief by the Court of the Lord Lyon. Discover Britain states that Clan Armstrong is armigerous and has no recognised clan chief.
However, the clan remains very active through heritage organisations, societies, family historians and the work connected with Gilnockie Tower.
Modern Armstrong identity can be found through:
-
Clan Armstrong societies
-
Gilnockie Tower and its archives
-
Border Reiver heritage
-
Tartan wearing
-
Genealogy research
-
Scottish and Ulster-Scots family history
-
Highland games and Scottish festivals
-
Diaspora communities in North America, Australia, New Zealand and beyond
The clan stands today as a symbol of strength, independence, endurance, Border identity and survival against the odds.
Chapter X: Legacy of Clan Armstrong
The story of Clan Armstrong is one of the most dramatic in Scottish Border history.
It begins in the contested lands between Scotland and England, rises through the power of the Border reivers, reaches legendary force through Johnnie Armstrong of Gilnockie, and survives royal suppression, dispersal and centuries of migration.
Its motto says everything:
Invictus Maneo — I remain unvanquished.
That is the Armstrong story in two words: unbroken survival.
From Gilnockie Tower to Mangerton, from the Debatable Lands to the Scottish diaspora, from reiver horsemen to Neil Armstrong walking on the Moon, the name has travelled further than almost any Border family could have imagined.
Clan Armstrong’s legacy is written in stone towers, Border ballads, tartan cloth, family memory and the pride of those who still honour the name.
