Cross Europe and the Atlantic with the MacKay diaspora, from Sir Donald MacKay of Far, first Lord Reay, who raised three thousand men from the Strathnaver country for Danish service in 1626, through the notorious Sutherland Clearances of Strathnaver from 1814, to Donald McKay of Jordan Falls, Nova Scotia, the celebrated Boston clipper-ship builder. Five waves of migration and six representative MacKay journeys.
