The Mitford family is a minor aristocratic English family that traces its origins in Northumberland back to the time of the Norman conquest. In the Middle Ages they had been Border Reivers based in Redesdale. The main family line had seats at Mitford Castle, Mitford Old Manor House and from 1828 the then-newly-built Mitford Hall. Several heads of the family served as High Sheriff of Northumberland.
A junior line, with seats at Newton Park, Northumberland and Exbury House, Hampshire descends via the historian William Mitford to his great-great-great-granddaughters, the Mitford sisters. The Mitford family was twice elevated to the British peerage, in 1802 and 1902, under the title Baron Redesdale.
The sisters, six daughters of David Freeman-Mitford, 2nd Baron Redesdale and Sydney Bowles, became celebrated and at times scandalous figures that were caricatured, according to The Times journalist Ben Macintyre, as "Diana the Fascist, Jessica the Communist, Unity the Hitler-lover; Nancy the Novelist; Deborah the Duchess and Pamela the unobtrusive poultry connoisseur".

Mitford sisters 
The sisters achieved notoriety for their controversial, but stylish lives as young people, then for their very public political divisions between communism and fascism. Nancy and Jessica became well-known writers. Deborah managed one of the most successful stately homes in England. Jessica and Deborah married nephews-by-marriage of prime ministers Winston Churchill and Harold Macmillan respectively. Deborah and Diana both married wealthy aristocrats. Unity and Diana were well known during the 1930s for being close to Adolf Hitler. In the early 1980s, Deborah became politically active when she and her husband Andrew Cavendish, 11th Duke of Devonshire became leaders of the new Social Democratic Party.
The sisters were the children of David Freeman-Mitford, 2nd Baron Redesdale, known to his children as "Farve" and various other nicknames. Their mother was Sydney Freeman-Mitford, Baroness Redesdale, known as "Muv", the daughter of Thomas Bowles. David and Sydney married in 1904. The family homes changed from Batsford House to Asthall Manor beside the River Windrush in Oxfordshire, and then Swinbrook Cottage nearby, with a house at Rutland Gate in London.
The sisters and their brother grew up in an aristocratic country house with emotionally distant parents and a large household with numerous servants; this family dynamic was not unusual for the time. There was also a disregard for formal education of women of the family, and they were expected to marry at a young age to a husband who was financially well-off. Their parents were described as "nature's fascists". At least two of their daughters followed in their footsteps; one turned her back on her inherited privileges, and ran away to become a communist, a result of the excitement of European politics in the 1930s. Jessica's memoir Hons and Rebels describes their upbringing, and Nancy obviously drew upon her family members for characters in her novels. The children had a private language called "Boudledidge" (pronounced 'bowdledidge'), and each had a different nickname for the others.
On the outbreak of the Second World War, their political views came into sharper relief. "Farve" remained a conservative, but "Muv" usually supported her fascist daughters and they separated in the late 1940s. Nancy, a moderate socialist, worked in London during the Blitz. Pamela remained seemingly non-political, although reportedly a rabid anti-Semite. Tom, a fascist, refused to fight Germany, but volunteered to fight against Imperial Japan. He was killed in action a short time after arriving in Asia. Diana (married to Sir Oswald Mosley), leader of the British Union of Fascists, was imprisoned in London for three years under Defence Regulation 18B. Unity, distraught over the war declaration against Germany, tried to commit suicide by shooting herself in the head. She suffered brain damage which eventually led to her early death. Jessica, a communist supporter, had moved to the US, but her husband Esmond Romilly volunteered for the RCAF and died when his bomber developed mechanical problems over the North Sea. In numerous letters Jessica stated that Jessica's daughter received a pension from the Canadian government from Esmond's death until she turned 18 years old. The political rivalry between Jessica and Diana lasted until their deaths. The other remaining sisters kept in frequent contact.
The sisters were prolific letter-writers. A substantial body of correspondence still exists, principally letters between them. They were, it has been alleged, "the most ardent burnishers of their own public image."

The Mitfords in Popular Culture 
A fictional family based on the Mitford sisters features prominently in author Jo Walton's novel Ha'penny; Viola Lark, one of the point-of-view characters, is one of the sisters, another is married to Himmler, and a third is a Communist spy.
The fictional "Combe sisters" in the BBC 2 series Bellamy's People bear a striking resemblance to the Mitford sisters. Bellamy meets two of the surviving Combe sisters, said to have been notorious in the 1930s and 1940s for their extreme political views, now living together in a strained relationship in the dramatically different political realities of 2010. One an avid Fascist and the other a committed Communist, the sisters have hit upon the solution of dividing their stately home down the middle, each converting her side into a homage to her ideology. The sisters were denied a formal education as children, and led an isolated childhood, forming an odd relationship and inventing their own language known as "Languish".
