On the northern shore of Loch Fyne, where the loch widens toward its head and the hills of Argyll rise steeply from the water, Dunderave Castle stands above a narrow rocky promontory in a position of considerable strategic command. The tower house — built around 1596 on a site whose fortification is believed to predate it significantly — was the seat of the MacNaughton chiefs and is the most enduring physical symbol of a clan whose roots in Argyll stretch back into the earliest records of the Scottish kingdom. Also written MacNaughton, Macnachtan, McNaughton, and in Gaelic Mac Neachdainn, the clan takes its name from the ancient Pictish personal name Nechtan — a name with roots in early Scottish kingship — and their motto I Hope in God is a declaration of faith that speaks to the spiritual grounding of a family that navigated the complex politics of medieval and early modern Argyll with remarkable persistence. Dunderave means the Fort of the Two Oars in Gaelic, a name that evokes the clan's command of the loch's waters as much as their occupation of the land above them.
Where Does the Name MacNaughton Come From?
The name MacNaughton derives from the Gaelic Mac Neachdainn, meaning "son of Nechtan." Nechtan is a personal name of Pictish origin that was borne by several early Scottish kings and nobles and that carries associations with the ancient culture of the northern and eastern Scottish kingdoms before the consolidation of the Gaelic tradition. The adoption of this name in western Argyll — a region more closely associated with the Gaelic inheritance from Ireland and the western islands — is notable, and it gives the MacNaughton family a genealogical identity that bridges the Pictish and Gaelic worlds of early Scotland.
The spelling variants — MacNaughton, MacNaughten, Macnachtan, McNaughton, MacNachton — all refer to the same Argyll kindred. The clan is traditionally associated with a number of sept names including MacBrayne and Hendrie, which reflect the range of families who maintained connections to the MacNaughton line across the centuries.
Where Did Clan MacNaughton Hold Their Lands?
The MacNaughton heartland was the district around Loch Fyne and Loch Awe in Argyll, the two great sea and freshwater lochs that defined the political geography of the western Highlands in the medieval period. Dunderave on the northern shore of Loch Fyne was the clan's principal seat, and the tower house built there in the late sixteenth century — restored sympathetically in the early twentieth century by the architect Sir Robert Lorimer — remains one of the finest examples of a Scottish tower house in the Argyll landscape. The castle's position above the loch shore, commanding views along the water toward Inveraray and the wider Fyne estuary, made it both defensible and demonstrative of the family's authority over this stretch of Argyll.
On Loch Awe, the MacNaughtons held Fraoch Eilean — the Heather Island — a small rocky islet at the northern end of the loch on which they maintained a fortified stronghold. This island castle, whose remains survive today, gave the clan a second point of control over the waterway system that connected Loch Fyne to the broader inner Highland landscape. The combination of lochside position and island fortress reflected a clan whose power was rooted in the command of water as much as of land, a characteristic of many Argyll kindreds whose territory was shaped by the sea lochs and freshwater lochs of the western mainland.
What Is the MacNaughton Clan Motto?
The MacNaughton motto is I Hope in God, rendered in Latin as Spero in Deo. It is a declaration of faith rather than of martial confidence, and it sits alongside the castle tower of the clan crest in a combination that balances spiritual trust with the practical reality of fortified stone. For a clan whose history involved repeated confrontation with the expanding power of the Campbells and whose territorial position in Argyll placed them in the path of one of the most aggressive expansionist families in Scottish history, a motto rooted in divine hope rather than in human strength has a particular honesty about it. The MacNaughtons could not always match Campbell power with their own; they placed their trust in something beyond it.

Who Were the Notable Figures of Clan MacNaughton?
The earliest traceable MacNaughton ancestor is generally identified as Nechtan Mòr, thought to have lived in the twelfth century, whose descendants established the family as landholders in Argyll by the thirteenth century. Alexander MacNaughton was among the chiefs who appear in the records of the thirteenth and fourteenth centuries as significant actors in the politics of western Scotland, their position on Loch Fyne placing them at the intersection of several major political currents during the Wars of Independence and the complex alliances that followed.
The MacNaughton chiefly line maintained its Dunderave connection through the sixteenth century before the pressures of debt and Campbell territorial expansion brought the estate out of family hands in the later seventeenth century. Tradition holds that the last MacNaughton chief to hold Dunderave lost the castle in circumstances connected to an arranged marriage that went wrong, a story whose specific details are recorded differently in different sources but whose outcome — the loss of the family seat — is well documented. After the loss of Dunderave, the chiefly line dispersed, with branches settling in County Antrim in Ireland where the MacNaughton name continues to this day in both its Scottish and Irish forms.
How Did Clan MacNaughton Relate to Their Argyll Neighbours?
The MacNaughtons' most defining relationship was with the Campbells, whose steadily expanding authority over Argyll progressively eroded the MacNaughton territorial position across the fifteenth, sixteenth, and seventeenth centuries. The story of the MacNaughtons in Argyll is in many ways the story of what happened to smaller kindreds as Campbell power consolidated, and the loss of Dunderave is among the more precisely documented examples of that process. The history of Clan Campbell illuminates this dynamic from the perspective of the dominant family, providing essential context for understanding the pressures that the MacNaughtons faced. On Loch Awe, the MacCallums were among the neighbouring kindreds whose own Argyll story overlapped with the MacNaughton experience; the history of Clan MacCallum provides a parallel account of a smaller Argyll clan navigating the same Campbell-dominated landscape.

What Happened to Clan MacNaughton After Dunderave?
The dispersal of the MacNaughton chiefly family from Argyll following the loss of Dunderave carried branches of the family to Ulster, where the MacNaughton name became established in County Antrim as part of the broader Scottish presence in the north of Ireland. The Ulster MacNaughtons maintained their distinct identity across subsequent generations, and the name is still found in Antrim today. In Scotland itself, MacNaughton families spread through the Lowlands and eventually across the Atlantic, with the name appearing in the records of Nova Scotia, Ontario, and the American eastern states as part of the Highland diaspora of the eighteenth and nineteenth centuries.
Dunderave Castle, restored by Sir Robert Lorimer in 1911 and now in private ownership, remains the most significant surviving physical monument to the clan's Argyll tenure. The castle is not generally open to the public but is visible from the A83 road that runs along the northern shore of Loch Fyne, and for any MacNaughton descendant passing through Argyll, the sight of the tower house above its narrow promontory provides a direct visual connection to the family's medieval heartland.
What Is the MacNaughton Legacy Today?
Clan MacNaughton today is maintained through the families who carry the name across Scotland, Ireland, Canada, the United States, and Australia, and through the heritage interest that connects those families to Dunderave, to Fraoch Eilean on Loch Awe, and to the Argyll landscape that shaped their origins. The motto I Hope in God endures as the clan's most compact declaration: a statement of faith that sustained a family through the loss of their territory and the dispersal of their community, and that carries across every generation that has borne the MacNaughton name since.
