Clan History and Origins

It is likely the Sinclairs came from St Clare in Normandy. They first went to England (before they came to Scotland) with William the Conqueror during his invasion of England. Richard of Saint-Clair and Brittel of Saint-Clair are both mentioned in the Domesday Book. William of Saint-Clair accompanied Saint Margaret of Scotland, daughter of Edward the Exile to Scotland in 1068, where she eventually married Malcolm III of Scotland. In return for his efforts, the king supposedly granted Sinclair the barony of Roslin, Scotland "in free heritage". The chiefs of Clan Sinclair descend from Sir William St Clare who was sheriff of Edinburgh and who was granted the barony of Roslin (Rosslyn) in 1280. In 1379, Sir Henry Sinclair claimed the Earldom of Orkney through his mother and received it from Haakon VI of Norway. The Sinclairs were later forced by James III of Scotland to resign the earldom of Orkney, and received instead the title Earl of Caithness. (Source: Wikipedia)
