Lady Vallance of Tummel obituary
Academic, charity leader and author of two books about female politicians
Elizabeth Vallance had a family history full of paradoxes. On her maternal side her grandfather, David Kirkwood, was a militant Red Clydeside trade unionist, the last person to be imprisoned in Edinburgh Castle during the First World War for sticking steadfastly to his pacifist views, and ultimately a member of the House of Lords. By contrast, her paternal grandfather, William McGonnigill, left Scotland aged 16 to become a cavalryman, defending the Khyber Pass against the Pashtuns and becoming pipe major of the Gordon Highlanders during the First World War, leading his regiment over the trenches, unarmed except for his bagpipes
....She was born Elizabeth Mary McGonnigill in 1945 to William McGonnigill, a company director, and Jean Kirkwood, a journalist...
Lady Vallance of Tummel, lecturer and campaigner, was born on April 8, 1945. She died of cancer on July 9, 2020, aged 75
