Item 1 - Holiday card, from Susan Buchan to "Mr. Gundy"

Susan Charlotte Buchan, Baroness Tweedsmuir (née Grosvenor; 20 April 1882 – 21 March 1977) was a British writer and the wife of author John Buchan. Between 1935 and 1940 she was viceregal consort of Canada while her husband was the governor general. She was also the author of several novels, children's books, and biographies, some of which were published under the name Susan Tweedsmuir.
Susan was a daughter of Norman de L'Aigle Grosvenor (son of the first Lord Ebury) and his wife Caroline Susan Theodora Stuart-Wortley (a granddaughter of the first Lord Wharncliffe), and a cousin of the Dukes of Westminster. She married John Buchan on 15 July 1907, and became the Baroness Tweedsmuir (known as Lady Tweedsmuir) when he was created Baron Tweedsmuir in 1935. The Buchans had four children, Alice, John, William, and Alastair, two of whom would spend most of their lives in Canada.
Her time as Vicereine of Canada is remembered for her energetic relief work. Her library project of gathering books in Eastern Canada for impoverished western communities and sending train carloads of them west was the foundation for many public libraries across the prairies.
Her interest in literary education influenced the establishment of the Governor General's Awards, for many years Canada's primary literary awards, and the library at Rideau Hall. Following her husband's death she returned to Britain, where she wrote several more novels, a series of memoirs, and a biography of her husband.
She died at Burford, near Oxford, in 1977 and was buried beside her husband in the churchyard at Elsfield.
