Lindy Guinness, also known as Lady Dufferin, The Marchioness of Dufferin and Ava, is a British conservationist, businesswoman, agriculturalist and artist. She is the daughter of Loel Guinness and Lady Isabel Manners, sister of Charles the the 9th Duke of Rutland. In 1964, she married the Marquess of Dufferin and Ava at Westminster Abbey.
As a girl she was a passionate artist. She met Duncan Grant when she was just 17, he became a close personal friend and had a huge influence on her life and her art. She has said, of their friendship, 'My whole development as a person and an artist is entwined with Duncan'. In 1965, she won a scholarship to the Slade School of Art. Before that she was a scholarship student in Salsburg under Oscar Kokoscka and did her postgraduate training at the Chelsea School of Art and evening classes and summer courses both at the Heatherly School of Art and the Byam Shaw.
She has exhibited extensively in London, Dublin and Belfast and has more recently had solo shows in Italy, Paris and New York. Her work today is continually inspired by the Irish countryside, the changing seasons and her herd of prize-winning cows. She currently divides her time between Holland Park and Clandeboye, the 2000 acre family estate in County Down, Northern Ireland, in which she is actively involved.
