The history of Clan Sinclair

The Sinclairs came to Britain from Saint-Clair-sur-Elle in Normandy. By the 14th century they held the earldom of Orkney from the Norwegian crown, and from 1455 the earldom of Caithness from the Scottish crown.

Sir William Sinclair, 1st Earl of Caithness, founded Rosslyn Chapel in the mid-15th century — its richly carved interior the subject of centuries of speculation about Templar and Masonic connections.

The Sinclairs of Caithness held their lands at the very north of mainland Scotland and remained a power in the region into the modern era; cadet branches spread across Scotland, Scandinavia and the New World.
