Clan MacEwan: A Legacy of Otter, Loch Fyne and Strength Renewed
Introduction
Clan MacEwan, also written MacEwen, McEwan, McEwen, Macewan, Macewen, MacEoghain, and related forms, is a historic Highland Scottish clan rooted especially in Argyll, Cowal, Otter, Kilfinan, Loch Fyne, Lennox, Galloway, Perthshire, and the wider Scottish diaspora.
The Gaelic name is:
MacEòghainn
meaning:
Son of Ewen
or
Son of Eòghan
The personal name Eòghan / Ewen is usually linked with ideas of:
youth
well-born
noble-born
or
born of the yew
The clan motto is:
“Reviresco”
“I grow strong again.”
The clan battle cry is:
“Co’mhla!”
“Together!”
The clan crest is:
The trunk of an oak tree sprouting Proper.
In simpler terms, this is an oak stump sending out new young shoots — one of the most fitting Scottish clan crests for a family that lost its old lands, survived for centuries without a chief, and has now been formally restored. Clan MacEwen Society gives the motto as Reviresco, meaning I grow strong again, and the battle cry as Co’mhla, meaning Together.
The historic heartland was:
The Barony of Otter, on Loch Fyne, in Cowal, Argyll.
The current chief is:
Sir John Roderick Hugh McEwen of Marchmont and Bardrochat, 5th Baronet
Chief of the Name and Arms of MacEwen
In 2025, the Lord Lyon recognised Sir John McEwen as the first Chief of the Name and Arms of MacEwen for roughly 575 years, ending one of the longest chiefless periods in Scottish clan history.
Chapter I: Origins of Clan MacEwan
The surname MacEwan / MacEwen comes from the Gaelic:
Mac Eòghainn
meaning:
Son of Ewen
or:
Son of Eòghan
Historic forms and related names include:
MacEwan
MacEwen
McEwan
McEwen
Macewan
Macewen
MacEoghain
MacEwen of Otter
MacEwan of Otter
Ewen
Ewan
Ewing, in some wider discussions
McKeown / McKewn, in some related or diaspora spellings
The clan is historically known as:
Clan MacEwen of Otter
or:
Clan Ewen of Otter
Modern clan summaries describe Clan MacEwen as a Scottish clan recorded in the 15th century as Clan Ewen of Otter.
Clan MacEwan’s early story is tied to Cowal, Loch Fyne, and the old Gaelic kindreds of Argyll. Electric Scotland states that the MacEwens claim a common ancestor, Anradan, with the Lamonts, MacLachlans, and MacNeils, and that these kindreds held much of Cowal.
Clan MacEwan is therefore a clan of:
Argyll roots
Loch Fyne territory
Otter chiefship
oak-tree renewal
Campbell-era displacement
centuries of chiefless survival
modern restoration
Its motto gives the clan its voice:
I grow strong again.
Chapter II: Clan Territory and Ancestral Lands
Clan MacEwan’s historic territory includes:
Otter
Kilfinan
Cowal
Loch Fyne
Argyll
Lennox
Galloway
Perthshire
The wider Scottish diaspora
The old clan heartland was:
The Barony of Otter
The Clan MacEwen Society describes the clan’s heartland as the Barony of Otter, in Cowal, with lands stretching across Loch Fyne, through Kilfinan, and into the surrounding Argyll landscape.
For Clan MacEwan, Otter represents:
the old chiefship
Loch Fyne identity
Cowal roots
the lost homeland
the remembered heart of the clan
The MacEwan landscape is classic west Highland Argyll:
sea lochs
oak woods
rocky shores
Gaelic kindreds
small castles
Campbell expansion
old parish memory
diaspora recovery
This is a clan story of loss and return.
Chapter III: Important People of Clan MacEwan
Ewen of Otter
The earliest remembered forebear is often given as:
Ewen of Otter
ScotlandShop states that the earliest MacEwen forebear was Ewen of Otter, who lived on the shores of Loch Fyne in Argyll around 1200, descended from the original Scots of Dalriada.
For Clan MacEwan, Ewen of Otter represents:
the naming ancestor
the old Argyll line
the beginning of the Otter tradition
the root of the clan name
Swene MacEwen of Otter
A critical figure was:
Swene MacEwen of Otter
He is remembered as the last chiefly figure before the clan lost its long-recognised chiefship. Modern summaries list Swene MacEwen as the last chief before the long chiefless period, with his death date given as 1493.
The surrender and inheritance of the barony in the 15th century became central to the clan’s later loss of lands and status.
The MacEwens of Otter
The MacEwens of Otter were the main chiefly family.
They held lands on Loch Fyne between neighbouring Argyll kindreds, including the Lamonts and MacLachlans. Electric Scotland describes the MacEwens as established on a strip of land along Loch Fyne between the Lamonts to the south and the MacLachlans to the north.
Sir John Roderick Hugh McEwen
The modern restoration centres on:
Sir John Roderick Hugh McEwen of Marchmont and Bardrochat, 5th Baronet
He was recognised by the Lord Lyon as Chief of the Name and Arms of MacEwen in 2025. COSCA reported that the Lord Lyon signed a warrant recognising him as the first MacEwen chief in 575 years.
This gives Clan MacEwan one of the most powerful modern clan revival stories in Scotland.
Chapter IV: Castles, Lands and Historic Sites
MacEwen’s Castle / Castle of Otter
The most important historic site is:
MacEwen’s Castle, also known as the old castle of Otter.
A 1794 Statistical Account passage, quoted in modern MacEwen research, described the remains of a building on a rocky point on the coast of Loch Fyne called Caesteal Mhic Eobhuin, or MacEwen’s Castle, associated with the MacEwen chief who held the northern division of Otter.
For Clan MacEwan, MacEwen’s Castle represents:
the old chiefly seat
the Otter homeland
Loch Fyne authority
the visible memory of a lost barony
Otter
Otter is the heart of the clan story.
It represents:
the barony
the chiefship
the clan’s old lands
the memory of displacement
the beginning of modern restoration
Kilfinan
Kilfinan is important because the lands of Otter lay within this Argyll parish landscape.
For MacEwan descendants, Kilfinan is a key research place for:
old parish records
local history
burial grounds
Loch Fyne settlement patterns
early MacEwen references
Loch Fyne
Loch Fyne is central to MacEwan identity.
For Clan MacEwan, Loch Fyne represents:
sea-road life
Argyll Gaelic culture
clan boundaries
Otter and Cowal roots
the western Highland world
Cowal
Cowal links the MacEwans with other ancient kindreds such as:
Lamont
MacLachlan
MacNeil
This wider Cowal context is essential to understanding the clan’s origin.
Chapter V: Loss, Survival and Restoration
Clan MacEwan’s most powerful historical theme is not conquest, but renewal.
Loss of the Barony
The MacEwens lost their old lands and chiefship after the medieval period.
Modern clan discussions often focus on the surrender of Otter in the 15th century and the later absorption of local power into the expanding Campbell sphere. The Clan Ewen of Otter history project notes the importance of the 1432 surrender of the barony by Swene MacEwen of Otter to King James I.
Campbell Expansion
The Campbells rose to overwhelming power in Argyll.
MacEwan lands and identity were affected by this shift in regional power. Research summaries note that the MacEwens were displaced by the Campbells around the later 15th century.
Centuries Without a Chief
For centuries, Clan MacEwan had no recognised chief.
This made it an armigerous clan for a long period: a clan with identity, history, tartans and followers, but no formally recognised chief.
Commander — 2014
In 2014, the Lord Lyon approved Sir John Roderick Hugh McEwen as Commander of Clan MacEwen, beginning a formal route toward restored leadership. A Highland Games clan profile notes that Sir John was approved as Commander in 2014, then nominated for chiefship after a family convention in June 2024.
Chiefship Restored — 2025
The great modern turning point came in 2025, when Sir John McEwen was recognised as chief.
COSCA reported that the Lord Lyon signed a warrant recognising Sir John Roderick Hugh McEwen of Marchmont and Bardrochat as Chief of the Name and Arms of MacEwen.
This makes the MacEwan motto almost prophetic:
Reviresco — I grow strong again.
Chapter VI: Clan Crest, Motto and Badge
Clan Crest
The MacEwan crest is:
The trunk of an oak tree sprouting Proper.
This means:
An oak stump sending out new young branches.
The symbolism is perfect for Clan MacEwan.
It suggests:
renewal
return after loss
life from old roots
strength after being cut down
a clan that could not be erased
Commercial clan crest summaries give the MacEwan crest as a trunk of an oak tree sprouting, Proper.
Clan Motto
The motto is:
“Reviresco”
This means:
“I grow strong again.”
It can also be rendered:
“I grow green again”
or
“I flourish again.”
ScotlandShop gives Reviresco as the MacEwen motto and translates it as I grow strong again, I grow green again, or I flourish again.
For Clan MacEwan, no motto could be more fitting.
It means:
the clan returns
the old roots live
the cut tree sprouts again
history can be restored
loss is not the end
Battle Cry
The battle cry is:
“Co’mhla!”
Meaning:
“Together!”
Clan MacEwen Society gives this as the clan battle cry.
This is ideal for a clan whose modern restoration depended on scattered descendants gathering again.
Clan Badge
The plant badge commonly associated with MacEwan is:
Oak
The oak matches the crest and the theme of renewal.
Oak suggests:
strength
deep roots
old lineage
endurance
growth from the ancient stump
Chapter VII: Clan MacEwan Tartans
MacEwen / MacEwan Tartan
The MacEwen / MacEwan tartan is recorded by the Scottish Register of Tartans under reference 2428.
The Register notes that the MacEwans settled in various parts of Lennox, Lochaber and Galloway, with information taken from W. & A. K. Johnston’s The Tartans of the Clans and Septs of Scotland.
MacEwen Clans Originaux Tartan
The MacEwen (Clans Originaux) tartan is also recorded by the Scottish Register of Tartans under reference 2427.
MacEwan / McKewn Tartan
A related MacEwan / McKewn tartan is also used in modern tartan contexts. Retail tartan summaries describe it as registered as a Clan/Family tartan and connect the MacEwans with ancestral lands later absorbed by the Campbells.
MacEwan Ancient, Modern and Weathered Options
Modern suppliers commonly offer MacEwan tartans in:
Ancient
Modern
Weathered
Muted, where available
The usual distinction is dye tone:
Ancient colours are softer and lighter.
Modern colours are deeper and stronger.
Weathered colours are muted and aged.
Muted versions are more restrained.
The Meaning of MacEwan Tartan Today
For modern MacEwan descendants, tartan represents:
Otter
Loch Fyne
Cowal
the restored chiefship
the oak-sprouting crest
the motto “I grow strong again”
the battle cry “Together”
family pride and diaspora identity
The MacEwan tartans give this restored Argyll clan a visible and wearable Scottish identity.

Today, Clan MacEwan has undergone one of the most significant modern restorations in the Scottish clan world.
The current chief is:
Sir John Roderick Hugh McEwen of Marchmont and Bardrochat, 5th Baronet
Chief of the Name and Arms of MacEwen
He was first recognised as Commander in 2014, nominated through a family convention in 2024, and recognised by warrant of the Lord Lyon in 2025.
Modern Clan MacEwan identity can be found through:
Clan MacEwen Society
family history research
tartan wearing
study of Otter, Kilfinan and Loch Fyne
research into Cowal and Argyll records
Scottish heritage events
Highland games
diaspora family networks
For MacEwan descendants, the best first step is to trace the family’s spelling and region:
MacEwan?
MacEwen?
McEwan?
McEwen?
Ewen?
Ewing?
Otter?
Cowal?
Loch Fyne?
Argyll?
Lennox?
Galloway?
Perthshire?
Ulster?
Canada?
Australia?
New Zealand?
The United States?
That will determine the strongest family-history path.
Chapter X: Legacy of Clan MacEwan
The story of Clan MacEwan begins on the shores of Loch Fyne.
From Ewen of Otter came the name.
From Otter came the barony.
From Cowal came the clan world.
From MacEwen’s Castle came the old seat.
From loss came silence.
From silence came survival.
From survival came restoration.
From the crest came the oak stump sprouting new branches.
Its motto gives the clan its voice:
Reviresco — I grow strong again.
That phrase captures the MacEwan spirit: cut down but not dead, displaced but not erased, forgotten by power but remembered by blood.
From Otter to Loch Fyne, from Argyll to descendants across the world, Clan MacEwan continues to carry its history forward.
Its legacy is written in tartan, oak shoots, old stones, restored chiefship, family records and the pride of those who still honour the name.
