According to Amy Young's book (page 6) 'Blaikie of Aberdeen', the Blaikie family are supposed to have come originally from the Border but in the '15 the father of David Blaikie was called out of the ranks and shown to the Pretender as one of the finest Highlanders being a very big man.He had a grant of land from the Earl of Perth.
Three clarifications including those provided by Amy are as follows:
The Border will refer to the Scottish border country near to England.
The '15, of course, was the rebellion of 1715 whereby the Scots objected to union with England,which for various complicated reasons became less attractive once Queen Anne (whose father had been relatively Scottish and seriously Catholic) was succeeded by King George, whose provenance was overtly teutonic, and whose accession to the throne was effectively a victory for the English 'Whig' establishment of the day.
The 'Pretender' was the English name for James Stuart, the lawful heir to the thrones of Scotland and England (James III of England:James VIII of Scotland) according to the Scots who supported this rebellion against England under King George.A scurulous story had been put about at the time of Jame's birth that he was not his mother's legitimate child but had been introduced at a very early age to the allegedly natal bed by means of a 'warming pan' (device for heating the bed) in order to provide an heir to King James II who lost his throne in 1688 on account of seriously having alarmed the wrong people.But thereby hangs another tale.
