Clan MacArthur: A Legacy of Loch Awe, Argyll and Fidelity Through Work
Introduction
Clan MacArthur, also known as Clan Arthur, is a historic Highland Scottish clan rooted especially in Argyll, Loch Awe, Inishail, Strachur, Milton, Tirivadich, the Isle of Skye, and the wider western Highlands and islands.
The Gaelic name is:
Clann Artair
meaning:
Children of Arthur
or
Descendants of Arthur
The clan motto is:
“Fide et Opera”
“By fidelity and work.”
The clan crest is:
Two branches of bay in orle Proper.
In simpler terms, this is two laurel or bay branches forming a wreath-like circle. The clan slogan is:
“Eisd, O Eisd!”
“Listen, O listen!”
The clan plant badge is:
Wild thyme.
The current chief is:
John Alexander MacArthur of that Ilk
Chief of Clan Arthur
Modern clan references identify John Alexander MacArthur of that Ilk as the current chief, following the restoration of the chiefship in the early 2000s after more than two centuries without a recognised chief.
Chapter I: Origins of Clan MacArthur
The surname MacArthur means:
Son of Arthur
The name comes from Gaelic:
Mac Artair
meaning:
son of Arthur
Related spellings and associated forms include:
MacArthur
Macarthur
McArthur
Arthur
Arthurson
MacArtair
MacArtur
MacArther
MacCarter
MacCartair
Carter, in some island traditions
Clan MacArthur has long been described as one of the old clans of Argyll. The clan is associated with the legendary name Arthur, which naturally gives it a strong heroic and early medieval atmosphere. Some traditions connect the name imaginatively with King Arthur, though the historically safer explanation is that the clan descends from a Gaelic ancestor bearing the personal name Arthur / Artair.
Clan Arthur and Clan Campbell are often said to share an early origin, and at one stage the MacArthurs challenged the seniority of the Campbell line in Argyll. Modern clan summaries note this shared-origin tradition and the MacArthurs’ former importance around Loch Awe.
This makes Clan MacArthur a clan of Argyll roots, Loch Awe power, ancient claims, Campbell rivalry, restored chiefship, Highland tartans and enduring loyalty.
Chapter II: Clan Territory and Ancestral Lands
Clan MacArthur’s historic territory includes:
Argyll
Loch Awe
Inishail
Strachur
Tirivadich
Milton
Drissaig
Glassary
Cowal
The Isle of Skye
The western Highlands
The wider Scottish diaspora
The most important ancestral landscape is:
Loch Awe
Clan Arthur once held lands on the shores of Loch Awe, opposite Inishail. Modern clan summaries describe the clan as once holding lands on the shores of Loch Awe opposite Inishail, and Inishail is also remembered as the burial place of the clan.
The MacArthur world is therefore a classic Argyll Highland landscape:
lochs
islands
church lands
burial grounds
clan rivalry
Campbell pressure
seafaring links
western Highland kinship
This is not a Lowland surname tradition. MacArthur is a true Highland clan name with deep roots in the west.
Chapter III: Important People of Clan MacArthur
The Early MacArthurs of Loch Awe
The earliest MacArthurs are remembered as a powerful kindred in the Loch Awe area.
They were part of the wider Argyll clan world, where power was built through land, kinship, marriage, warfare and alliance.
The MacArthurs and Clan Campbell
Clan MacArthur and Clan Campbell share a strong early-history connection.
At one point, the MacArthurs were important enough to dispute precedence with the Campbells. Later, Campbell power grew enormously in Argyll, while MacArthur power declined.
This tension forms one of the most important themes in MacArthur history: an old clan overshadowed by one of Scotland’s most powerful houses.
MacArthur of Milton
The MacArthurs of Milton became important in the later chiefship history.
The restored chiefship was connected through descent from the MacArthurs of Milton and Drissaig. Modern clan summaries state that genealogical research linked John MacArthur of Milton, who died in 1674, back to John MacArthur of Drissaig, helping establish the modern chiefship claim.
James Edward Moir MacArthur of that Ilk
A major modern figure was:
James Edward Moir MacArthur of that Ilk
In 2002, he was recognised by the Lord Lyon as the rightful heir to the arms of MacArthur of Tirivadich and as entitled to the chiefship of Clan Arthur. He was formally inaugurated as chief in 2003, becoming the first recognised chief of the clan in about 230 years.
This was one of the great modern restorations of Scottish clan chiefship.
John Alexander MacArthur of that Ilk
The current chief is:
John Alexander MacArthur of that Ilk
He succeeded his father, James Edward Moir MacArthur, after the latter’s death in 2004. He represents Clan Arthur as a member of the Standing Council of Scottish Chiefs.
Chapter IV: Castles, Lands and Historic Sites
Loch Awe
Loch Awe is the great ancestral landscape of Clan MacArthur.
It represents:
Old clan power
Argyll roots
MacArthur-Campbell rivalry
Inishail burial tradition
The heart of early Clan Arthur identity
The clan’s old lands lay on the shore of Loch Awe opposite Inishail.
Inishail
Inishail, in Loch Awe, is recognised as an important burial place of the clan.
For Clan MacArthur, Inishail represents:
Ancestral memory
Sacred ground
Burial tradition
The old spiritual heart of the clan
Strachur
Strachur is often mentioned in connection with the wider MacArthur and Campbell history of Argyll.
It belongs to the geography of Cowal and Loch Fyne, where west Highland clan power was shaped over centuries.
Milton and Drissaig
Milton and Drissaig are important because of the restored chiefship line.
Modern genealogical research connected the modern chiefship claim through the MacArthurs of Milton and Drissaig.
Skye
A branch of MacArthurs from the Isle of Skye became associated with Clan Donald, especially the MacDonalds of Sleat.
Modern clan summaries note that Skye MacArthurs were hereditary pipers to the MacDonalds of the Isles and were connected with the MacDonalds of Sleat.
This gives the clan a second strong Highland identity beyond Argyll: the island world of piping, Gaelic culture and Clan Donald service.
Chapter V: Clan Events, Rivalries and Restoration
Clan MacArthur history is shaped by early Argyll power, Campbell rivalry, loss of chiefship, Skye piping tradition and modern restoration.
Old Argyll Power
Clan MacArthur was once strong in Argyll, especially around Loch Awe.
The clan’s claim to age and seniority gave it a proud place among western Highland families.
Rivalry and Decline
The rise of Clan Campbell changed the balance of power in Argyll.
The Campbells became one of Scotland’s greatest noble houses, while MacArthur influence diminished.
This did not erase the MacArthur name, but it changed its political position permanently.
The Death of the Chiefly Line
By the late 18th century, the chiefly line had effectively failed, leaving Clan Arthur without a recognised chief for more than two centuries. Modern sources state that the clan was leaderless until the late 20th and early 21st centuries.
The 1991 Derbfine
In 1991, a derbfine was organised by armigers of the clan to identify the best claimant.
The meeting determined that James Edward Moir MacArthur of Milton should petition the Lord Lyon to become Clan Commander, which eventually led to formal recognition.
Restoration of the Chiefship — 2002 / 2003
In August 2002, James Edward Moir MacArthur was recognised by the Lord Lyon as heir to the arms of MacArthur of Tirivadich and entitled to the chiefship.
In April 2003, he was inaugurated by clan members as Chief of Clan Arthur — the first official chief in about 230 years.
This restoration is one of the most important modern events in MacArthur history.
Chapter VI: Clan Crest, Motto and Badge
Clan Crest
The MacArthur crest is:
Two branches of bay in orle Proper.
This means two laurel or bay branches arranged in a circular form. Modern clan summaries and crest references give this as the chief’s crest.
The bay or laurel branches suggest:
Honour
Victory
Achievement
Worthiness
Peace after struggle
A restored name crowned by endurance
For Clan MacArthur, the laurel is especially fitting because the clan’s chiefship was not merely inherited quietly — it was restored after centuries.
Clan Motto
The motto is:
“Fide et Opera”
This means:
“By fidelity and work”
or
“By faith and work.”
Clan crest references give this motto directly for MacArthur.
It means:
Loyalty must be lived
Faith requires action
Work proves commitment
A clan survives through effort
For Clan MacArthur, this motto is extremely appropriate. The modern clan identity was rebuilt through fidelity to the name and the hard work of genealogical restoration.
Clan Slogan
The slogan is:
“Eisd, O Eisd!”
This means:
“Listen, O listen!”
Modern clan summaries list this as the clan slogan.
It has the feeling of a Highland call — urgent, commanding and rooted in oral tradition.
Clan Badge
The plant badge is:
Wild thyme
Modern clan summaries list wild thyme as the plant badge of Clan Arthur.
Wild thyme suggests:
Hardiness
Fragrance
Highland ground
Quiet resilience
Strength in small things
Chapter VII: Clan MacArthur Tartans
MacArthur Tartan
The MacArthur tartan is recorded by the Scottish Register of Tartans under reference 2278.
The Register lists it as a Clan/Family tartan, designed by the Sobieski Stewarts, with a tartan date of 1 January 1842.
This is the most commonly used MacArthur tartan today.
MacArthur Variant Tartan
The MacArthur Variant tartan is also recorded by the Scottish Register of Tartans under reference 2279.
MacArthur Highland Society Tartan
The MacArthur Highland Society tartan is recorded by the Scottish Register of Tartans under reference 2280.
MacArthur of Milton Hunting Tartan
The MacArthur of Milton Hunting tartan is considered one of the older MacArthur tartans.
Modern clan summaries state that it is similar to Campbell tartans and is considered the elder of the MacArthur tartans, with a source in Wilson’s 1823 sample book.
Skye MacArthur and Clan Donald Tartan Links
The Skye MacArthurs, as hereditary pipers to the MacDonalds, have tartan associations connected with the MacDonald, Lord of the Isles tradition.
The Meaning of MacArthur Tartan Today
For modern MacArthur descendants, tartan represents:
Loch Awe roots
Argyll identity
The restored chiefship
The motto “By fidelity and work”
The laurel crest
Wild thyme plant badge
Skye piping traditions
Family pride and diaspora identity
The MacArthur tartans give this ancient Argyll clan a visible and wearable Scottish identity.
Chapter VIII: Heritage, Identity and Clan Traditions
Clan MacArthur represents a Highland identity built on ancient name tradition, Argyll landholding, Campbell rivalry, Skye piping, loyalty and restoration.
Its story includes:
Clann Artair
Loch Awe
Inishail
Argyll roots
MacArthur and Campbell shared-origin tradition
Milton and Drissaig chiefship links
Skye MacArthur pipers
MacDonalds of Sleat association
The 1991 derbfine

MacArthur
McArthur
MacArtair
MacCarter
MacCartair
Carter, especially in some island traditions
Clan lists also include wider spelling variants such as MacArther, MacArt, MacArtan, MacCarter, MacCartair and related forms.
Chapter IX: Clan MacArthur Today
Today, Clan MacArthur has a recognised living chief:
John Alexander MacArthur of that Ilk
Chief of Clan Arthur
He succeeded after the death of his father, James Edward Moir MacArthur of that Ilk, in 2004.
Modern Clan MacArthur identity can be found through:
Clan Arthur / Clan MacArthur organisations
Family history research
Tartan wearing
Study of Loch Awe and Inishail
Research into Milton and Drissaig
Skye piping history
Scottish heritage events
Highland games
Diaspora family networks
For MacArthur descendants, the best first step is to trace the family’s region:
Argyll?
Loch Awe?
Inishail?
Milton?
Drissaig?
Strachur?
Skye?
Clan Donald territory?
Ulster?
Canada?
Australia?
New Zealand?
The United States?
That will determine whether the strongest family-history path is Argyll MacArthur, Skye MacArthur, Clan Donald-associated MacArthur, or another Scottish diaspora line.
Chapter X: Legacy of Clan MacArthur
The story of Clan MacArthur begins with a name of legend:
Arthur.
From that name came Mac Artair — son of Arthur.
From Loch Awe came the old Argyll heartland.
From Inishail came sacred memory.
From Skye came the piping tradition.
From the loss of chiefship came centuries of silence.
From the restoration of the chiefship came renewal.
Its crest, the bay branches, speaks of honour and victory.
Its badge, wild thyme, speaks of quiet Highland endurance.
Its slogan calls out:
Eisd, O Eisd — Listen, O listen!
Its motto gives the clan its voice:
Fide et Opera — By fidelity and work.
That phrase captures the MacArthur spirit: loyalty proven by action, heritage rebuilt by effort, and an ancient name carried forward into the modern world.
From Loch Awe to Skye, from Argyll to descendants across the world, Clan MacArthur continues to carry its history forward.
Its legacy is written in tartan, laurel, wild thyme, loch waters, island burial grounds, piping tradition, family records and the pride of those who still honour the name.
