Sinclair Clan Origins & History
We proudly offer the Sinclair Tartan, a symbol of one of Scotland’s most noble and historic clans. Wearing the Sinclair Tartan is more than style — it’s a connection to centuries of loyalty, valor, and tradition.
From the Start
The story of Clan Sinclair begins not in Scotland but across the channel in Normandy, France, in the commune of Saint Clair. Norman Saint Clairs accompanied William the Conqueror to England in 1066. Two years later, William of Saint Clair journeyed to Scotland with Saint Margaret to marry Malcolm III. For this, the King granted William the barony of Roslin near Edinburgh, marking the start of the Sinclair family’s enduring Scottish legacy. The spelling “Sinclair” came into common use around the late 1400s, while the Roslin branch retained “St Clair.”
Sinclair’s Worldwide Presence
Though Caithness and Orkney remain the clan’s historic heartlands, Sinclair families have spread worldwide. The clan’s major branches are led by the Earl of Caithness, Earl of Rosslyn, Lord Sinclair, Viscount Thurso, and Sir Patrick Sinclair of Dunbeath.
Sinclair Support of the Jacobites
The Jacobite risings revealed complex allegiances: Sinclairs supported the Jacobite cause in 1715 but shifted to the British Hanoverian side by 1745. At the Battle of Culloden in 1746, Sir James Sinclair of Rosslyn commanded the Royal Scots regiment fighting for the Hanoverians.
Are Sinclairs Vikings?
Surprisingly, Sinclairs have Viking roots. They descend from Rognvald ‘The Mighty,’ Jarl of Orkney and Romsdahal, born in 835. His son, Rollo, signed a 921 peace treaty with King Charles of France in St-Clair-sur-Epte, inspiring the family name. The clan likely settled in Scotland in the late 11th century.
Clan Sinclair Battles
The Sinclairs were deeply involved in Highland clan conflicts, notably with Clan Sutherland. The 1570 Battle of Torran-Roy saw clashes with the Gordons and Sutherlands. Subsequent feuds included the siege of Dornoch Castle and a tragic imprisonment and death of John Sinclair at Castle Sinclair Girnigoe in 1576.
They also fought Clan Gunn and Clan Mackay, losing the 1585 Battle of Allt Camhna. The 1680 Battle of Altimarlach against Sir John Campbell of Glenorchy was one of Scotland’s last clan battles, ending in heavy Sinclair losses but eventual legal restoration of their earldom.
Where Does the Name Sinclair Come From?
The name “Sinclair” means “holy light,” reflecting the clan’s Norman origins and spiritual roots.
A Powerful Clan
Sinclairs have shaped Scotland’s history through castle building, maritime exploits, and cultural contributions. Rosslyn Chapel, founded by Sir William St Clair in 1446, remains a spiritual and historical landmark.
Castle Sinclair Girnigoe
