She attended
Somerville College, Oxford, graduating in 1960 with a degree in English. From 1965 to 2002, Townsend served as a
lady-in-waiting to
Princess Margaret, Countess of Snowdon. Margaret had requested that the appointed person be equipped to help supplement her perceived lack of a formal education. Townsend wrote a book recording "every village, church, stately home and architectural curiosity" within
Northamptonshire, publishing it in 1968. Her next literary project, a children's story set during the
Indian Mutiny, was released in 1971. She held an almost forty-year membership in the Northamptonshire branch of the
Campaign to Protect Rural England, and served as its president from 1988 to 1998. She left the position after her appointment as
Lord Lieutenant of Northamptonshire, the first woman to hold this role. She retired in June 2014, citing mobility difficulties. ==Honours==
