Margaret Greville is remembered by most people, if they remember her at all, as the elderly woman who left her jewels to the Queen Mother. That brief description captures only the final chapter of a far stranger and more remarkable life. Born in December 1863 in a London back street, she entered the world under a false name. The birth certificate recorded her as Margaret Helen Anderson, daughter of Helen Anderson and William Murray Anderson, a porter.
The porter existed, but he was not her father. The real father was Helen Anderson’s employer, William McEwan, a rising Edinburgh brewer. The porter had accepted legal responsibility for a child that was not his, an arrangement common enough in Victorian England and never documented. Margaret grew up in London in a household funded by her biological father, known quietly as McEwan’s girl.
She was educated at home, taught to write neatly, play piano, and keep a diary. In 1885, the porter died, and William McEwan married Helen Anderson. Margaret, then 21, was formally acknowledged as McEwan’s daughter. She never spoke publicly about the years before, effectively retiring the porter’s name forever.
McEwan had made a fortune in beer. He founded the Fountain Brewery in Edinburgh in 1856 with £2,000 from family capital. By the turn of the century, the firm controlled roughly 90 percent of the bottled ale trade in northeast England and exported across the British Empire. Money on that scale could buy almost anything in late Victorian Britain: a house in Mayfair, a seat in Parliament, the goodwill of a university.
McEwan served as Liberal MP for Edinburgh Central from 1886 to 1900 and gave the University of Edinburgh its Great Graduation Hall, known ever since as the McEwan Hall. What beer money could not buy was a peerage. A brewer could sit in the Commons but could not be made a lord. McEwan understood the line drawn at trade.
He also understood that his daughter could cross it, through the right marriage. In the summer of 1891, Margaret McEwan married the Honorable Ronald Greville. He was a guards officer, a personal friend of the Prince of Wales, and the eldest son of the second Baron Greville. He brought the name, the title in prospect, and immediate entry into the Marlborough House set, the private circle around the future King Edward VII.
She brought the McEwan money. Neither party was under any illusion about the exchange. Contemporary accounts describe a marriage of genuine affection. Ronald was easy-tempered; Margaret was sharper, funnier, and more ambitious.
They took a large house at 16 Charles Street in Mayfair, and Margaret began to give dinners that would redraw the guest list of political London. She became one of the half-dozen women at the center of the political circuit. She learned the private language of the Foreign Office and the private grievances of the War Office, heard them directly from the men who ran them over her own table. By the turn of the century, she was regarded as second only to Nancy Astor as the sharpest hostess in London.
In 1906, Margaret bought Polesden Lacy, a Regency villa on the North Downs in Surrey. The purchase was made in her sole name. She commissioned the architects Mewès and Davis, then completing the Ritz Hotel in Piccadilly, to remodel the interior entirely. The exterior was left almost untouched, but behind that modest face they built one of the most theatrical Edwardian house interiors in England.
The centerpiece was a great double-height saloon, fitted with carved and gilded paneling imported from an Italian palazzo, with painted canvases set into the ceiling. It was, in effect, a stage built to entertain a king. King Edward VII had agreed to come down for a house party, so Margaret ordered a complete bedroom suite built for his sole use. He used it several times between June 1909 and his death in May 1910.
Ronald Greville died in April 1908 at age 43, before the paint was fully dry. Margaret was 44, childless, and a widow. She never remarried. Instead, she took sole command of the enterprise, running the great house and the entire operation in her own name for the rest of her life.
In July 1913, her father died, leaving an estate valued at approximately £1. 5 million. From that summer, Margaret was one of the richest women in Britain. She spent the money on the operation: up to 30 resident indoor servants during the season, a full establishment in London, and the maintenance of a guest list that included Winston Churchill, foreign ambassadors, and royalty.
When King Edward VII arrived in June 1909 for the first royal weekend, everything was ready. The guests were assembled in the saloon. Margaret wore a ruby and diamond bandeau necklace from Boucheron. The king, by well-attested contemporary report, called her a genius.
He meant it professionally: she had built an operation that allowed him to be entirely at ease, four days at a time, in a way he could not be at Sandringham or Balmoral. After his death in 1910, George V and Queen Mary came in their own right. The pattern held for the next three decades. Guests arrived Friday afternoon and left Monday morning.
Dinner was at 8. The men withdrew to the library. The women took coffee in the gold room. The service wing ran invisibly behind walls, with a bellboard in the butler’s pantry as the nervous system and two entirely separate back stairs, one for each sex.
In 1915, Margaret offered Polesden Lacy to the War Office, and the state rooms were turned into wards for wounded officers of the British Expeditionary Force. She underwrote the cost of running the hospital out of her own income. In the New Year Honors of 1922, George V made her a Dame Commander of the Order of the British Empire in recognition of her hospital work. She accepted the ribbon but did not use the title.
She used to say she would rather be a beeress than a peeress. In April 1923, Margaret gave the house to the Duke and Duchess of York for the first two weeks of their marriage. The young couple stayed a fortnight. It was Margaret’s own idea, made in the knowledge that they had few private options for a honeymoon.
The relationship that formed that spring deepened over the following years. She wrote to Queen Mary in 1928 that the Duke had entirely won her heart and filled a great gap in her life. The gap was that Margaret had no children. From 1923 until her death, the Duchess, later Queen Elizabeth, became as close to a daughter as her life permitted.
After the abdication of Edward VIII in December 1936, the Duke and Duchess became King George VI and Queen Elizabeth. Margaret was part of the small circle that helped the new queen settle into the role she had not sought. There is a darker chapter. During the 1930s, Margaret entertained Joachim von Ribbentrop, the German ambassador, at both Charles Street and Polesden Lacy.
She spoke approvingly of Hitler in private letters, attended the Nuremberg rally at least once, and was among the pro-German voices in London high society. She was not alone in this, but it was her error. The Munich agreement of 1938 and the German seizure of Czechoslovakia in March 1939 changed her mind. By the summer of 1939, she admitted in writing that she had been wrong about Germany and would entertain no more German officials.
The war effectively ended the great house parties. Polesden Lacy was requisitioned as a maternity home in 1940. Margaret, nearly 77 and suffering badly from arthritis, moved into a suite at the Dorchester Hotel in London, where she lived for the last three years of her life. She remained sharp until the end.
Queen Elizabeth came to visit when she could. Margaret died in her suite at the Dorchester on September 15, 1942, aged 78. She was buried in the walled rose garden at Polesden Lacy, the only person ever buried there. Her will, signed six months before her death, delivered two extraordinary gifts.
Polesden Lacy and about 1,000 acres of its estate went to the National Trust in memory of her father, as a free gift with an endowment and no legal fight. She left £20,000 to Princess Margaret, £25,000 to Queen Ena of Spain, and named every senior servant with specific sums and specific pieces of furniture. The bulk of the jewelry collection, more than 60 pieces of first-class jewelry built at Boucheron and Cartier over four decades, went to Queen Elizabeth. The bequest included the emerald kokoshnik tiara of 1919, the Boucheron honeycomb tiara of 1921, the Cartier ivy leaf tiara of 1923, the Greville emeralds, and the great chandelier earrings.
The will expressed the wish that the pieces be worn by queens. The wish has been kept. Three successive queens or queens consort have worn them at state occasions across the eight decades since her death. In March 2023, Queen Camilla wore the Boucheron honeycomb tiara at a state banquet in Berlin during the first state visit of King Charles III’s reign.
The Cartier ivy leaf tiara has been worn by the Princess of Wales at state banquets. The jewels remain in active, continuous royal use today. Polesden Lacy has been open to the public since 1944. The house stands much as Margaret left it.
The gardens are maintained. School parties come through the state rooms, and visitors can walk to the small plain grave in the rose garden, inscribed with the name Dame Margaret Helen Greville. She had bought her way in. She had paid the bill.
And in the end, she paid it in a coin that has outlasted every peer of her generation. The queen who knew her best summed her up in the days after her death: so shrewd, so kind, so amusingly unkind, so sharp, so fun, so naughty. That verdict, from the person best placed to offer it, remains the truest ever given on Margaret Greville.
