Clan MacDonald (Isles) — History, Crest, Motto, Septs, Tartan

Celebrate your MacDonald of the Isles heritage with authentic details drawn from Scottish tradition.

History & Origins

The Clan Donald of the Isles, descended from Somerled, Lord of the Isles, represents one of the most powerful branches of Clan Donald. Their influence spanned the Hebrides and the western seaboard of Scotland, with dominion often rivaling that of the Scottish crown itself. The Lordship of the Isles was established in the 12th century and became a formidable maritime power.

As High Chiefs of Clan Donald, the MacDonalds of the Isles held sway over many other clans and septs, their authority stretching across the Hebrides and western Highlands. The fall of the Lordship in 1493 marked a turning point, yet the legacy of the Isles branch continues as one of the greatest symbols of Gaelic independence and seafaring strength.

Crest & Motto

• Crest: A hand holding a cross crosslet fitchée Gules (a red cross).

• Motto: Per Mare Per Terras — “By sea and by land,” emphasizing their maritime dominance and Highland authority.

• Badge Etiquette: Clansfolk wear the crest within a strap-and-buckle design, proudly displaying the motto.

Septs & Associated Names

Septs of the MacDonalds of the Isles include a wide range of surnames associated with Clan Donald generally, such as:

• Donaldson

• MacDonnell

• MacConnell

• MacDaniel

• McDonell

Because the Isles branch formed the central leadership of Clan Donald, many Highland families aligned with their cause and became recognized as septs.
