Mary Soames, Baroness Soames LG DBE FRSL (née Spencer-Churchill) was the youngest of the five children of Winston Churchill.



Mary Spencer-Churchill was raised at Chartwell and educated at the Manor House at Limpsfield. She worked for the Red Cross and the Women's Voluntary Service from 1939 to 1941, and joined the Auxiliary Territorial Service with whom she served in London, Belgium and Germany in mixed anti-aircraft batteries, rising to the rank of Junior Commander (equivalent to Captain). She also accompanied her father as aide-de-camp on several of his overseas journeys, including his post-VE trip to Potsdam, where he met with Harry S Truman and Joseph Stalin.

She served many public organisations, such as the International Churchill Society, as a Patron; Church Army and Churchill Houses; and chaired the Royal National Theatre Board of Trustees between 1989 and 1995. She was Patron of the National Benevolent Fund for the Aged.

A successful author, Lady Soames wrote an acclaimed biography of her mother, Clementine Churchill, in 1979. She offered insights into the Churchill family to various biographers, prominently including Sir Martin Gilbert, who became the authorised biographer of Sir Winston Churchill after the death of Churchill's son, Randolph, in 1968. Additionally, she published a book of letters between Sir Winston and Lady Churchill, editing the letters as well as providing bridging material that placed the letters in personal, family, and historical context.

Lady Soames was made a Dame Commander of the Order of the British Empire for her public service, particularly in Rhodesia. She was appointed a Lady Companion of the Order of the Garter on 23 April 2005 and was invested on 13 June at Windsor Castle.



Wife of Christopher Soames, Baron Soames and mother of Nicholas, Emma, Jeremy, Charlotte and Rupert.



On 31 May 2014, Lady Soames died at her home in London at the age of 91 following a short illness. Her ashes are buried next to those of her husband within the Churchill plot at St Martin's Church, Bladon, near Woodstock, Oxfordshire.
