Book excerpt: The Honourable Ruaraidh Erskine of Marr led a life very much on the move. He has left us no personal papers, although his stamp is across the personal papers of many others, and he has been written about by several eminent scholars. Erskine had his supporters, most notably the historian and Gaelic language activist, Seumas Mac A’ Ghobhainn, who hailed him as a ‘forgotten Gaelic patriot’. He has had his critics too: the BBC’s Andrew Marr, wrote that ‘in colloquial terms he was a bit of a nutter’. However, Hugh MacDiarmid said regarding Erskine: ‘Justice will be done to him yet with a biography’. This is it and it is long overdue.
