Princess Anastasia of Greece and Denmark (20 January 1878 – 29 August 1923) was a wealthy American heiress, Nonie "Nancy" May Stewart Worthington Leeds, who became a member of the Greek and Danish Royal Families through marriage to Prince Christopher of Greece and Denmark, the youngest child of King George I of Greece and his consort, Grand Duchess Olga Constantinovna of Russia.

Youth

She was born May Stewart in Zanesville, Ohio, in the United States on 20 January 1878, to William Charles Stewart, a wealthy merchant, and his wife, Mary Holden Stewart, who had been married since 11 December 1874 By 1880 the Stewart family had moved to Cleveland, Ohio, where it appears that May's mother died not long afterward, and her father remarried. May was educated at home until the age of seventeen, when she was sent to the Miss Porter's School for young ladies in Farmington, Connecticut. She was soon introduced to high society.

First and second marriages

As "Nonie May Stewart", on 1 October 1894 in Cleveland, she married George Ely Worthington, son of Ralph Worthington, who was a son of major Cleveland industrialist George Worthington. The marriage license inaccurately states that she was born in 1876, since Ohio law required that females be at least 18 years of age to marry. The couple lived as man and wife for four years, having no children.

It is unclear how or where, but the marriage ended on 23 March 1899 by divorce, annulment or abandonment, but the 1900 U.S. census records that "May Worthington" was again living with her father and step-mother in Cleveland that year (George Worthington had been born in Cleveland on 7 May 1872 and would die in Temple City, California on 22 August 1950 leaving a widow and three children, having long outlived Princess Anastasia). Since the original marriage was contracted under false pretences and while May was legally underage, annulment is plausible.

On 3 August 1900 Miss "Nonie May (Stewart) Worthington" married for the second time in Cleveland; the groom being William Bateman Leeds, born in Richmond, Indiana on 10 September 1861. This was also Leeds' second marriage, the previous one having ended in 1896, at which time he settled one million dollars on his ex-wife. Nonie May and Leeds had one son, William Bateman Leeds, Jr., born on 19 September 1902. Leeds died in 1908 in Paris, France, leaving a fortune estimated at 35 million dollars and a reputation as America's "Tin King" based on his financial success in plating and marketing that metal.

Third marriage

The wealthy, 30-year-old widow, soon to be known on the continent as "Nancy May Leeds", chose to remain in Europe, where she socialised among the aristocracy. Mrs. Leeds was a noted client of Cartier's, having her own hall in this famous jewellery shop. She started collecting valuable art and furniture.

In a memoir, published shortly before his death, Prince Christopher of Greece and Denmark, 1888–1940, addressed the persistent rumours alleging that his first wife was much older than he and that he married her for profit: The truth, he wrote, was that he met Mrs. Leeds, who was only four years his senior, in Biarritz, France in 1914 where they fell in love, eventually resolving to marry for no other reason.

Their engagement was announced to the public in 1914 on the island of Capri. The wedding was delayed due to reservations within the Royal Family about the prince's marriage with an American commoner who had been twice married. After the First World War when the dynasty went into exile and lived in much reduced circumstances, family opposition to Prince Christopher's wealthy bride-to-be subsided.

The Orthodox wedding took place on 1 February 1920 in Vevey, Switzerland, six years after the engagement. Four days later the bride joined the Greek Orthodox church taking, as was usual, a new Christian name; Anastasia. Henceforth she was officially styled HRH Princess Anastasia of Greece. However, the U.S. press continued to refer to her as the "Tin Plate Heiress", the "Dollar Princess" or the "Million Dollar Princess".

When Princess Anastasia's 19-year-old son, William B. Leeds, Jr., married her husband's 18-year-old niece, Princess Xenia Georgievna of Russia, in 1921, she is said to have objected because of the couple's youth. She denied rumors that her son would be given a title by the King and convert to the Orthodox faith prior to the marriage. Leeds and Princess Xenia Georgievna were married in Paris, raised a family in the United States, and divorced in New York in March 1930.

Shortly after her marriage to Prince Christopher, Anastasia was diagnosed with cancer. She died three years later in 1923 at Spencer House, London. According to her will, her remains were returned to the United States and she was buried with her parents in the family mausoleum at Woodlawn Cemetery in Bronx, New York City. In 1929 her widower would remarry, fathering a son, Prince Michael of Greece and Denmark in 1939, by his second wife, Princess Françoise of Orléans (1902–1953).
