Best known as the wife of British Prime Minister Winston Churchill, she served during World War II as the leader of the Young Women's Christian Association's wartime efforts and also assisted in the Red Cross's efforts to provide relief in Russia.
She was the child of Lady Blanche Hozier and (allegedly) Sir Henry Hozier (she was more likely the biological daughter of one of her mother's lovers). As a young woman, she studied in Edinburgh, Hertfordshire, and Paris.
In 1946, she was given the title of Dame Clementine Churchill GBE.
Several years prior to her marriage to Winston Churchill, she was secretly engaged to politician and military man Sidney Peel. Her marriage to Churchill resulted in four daughters (Diana, Sarah, Mary, and Marigold) and one son (Randolph).
She and Winston Churchill were married at St. Margaret's Church, Westminster, in September of 1908.
