Frances Catherine Partridge CBE (née Marshall; 15 March 1900 – 5 February 2004) was an English writer.
Born in Bedford Square in London, she was the youngest of six children of William Marshall, an English architect and losing finalist at the first of the Wimbledon Tennis Championships in 1877, and Margaret Anna Lloyd, a suffragist who took the 6-year-old Frances to a protest.
An added complication was Dora Carrington's intermittent affair with one of Partridge's best friends, Gerald Brenan.
After Dora Carrington committed suicide out of grief in 1932, shortly after Lytton Strachey's death, Ralph and Frances married on 2 March 1933.
Her writings, her membership of the Bloomsbury circle, her great personal charm and the energy that she retained into extreme old age together ensured for her a degree of celebrity towards the end of her life.
