Trace the extraordinary story of Clan MacGregor, from the proscription of the name from 1603 to 1774 that forced MacGregors to adopt other surnames, to Sir Gregor MacGregor of Edinchip in Perthshire (born 1786) and his infamous Poyais scheme, and William MacGregor of Towie in Aberdeenshire, colonial administrator and Governor of Queensland. Five waves of migration and six representative MacGregor journeys.
