Mary Fleming was the youngest child of
Malcolm Fleming, 3rd Lord Fleming, and
Lady Janet Stewart. She was born in 1542, the year her father was taken prisoner by the English at the
Battle of Solway Moss. Her mother was an illegitimate daughter of James IV of Scotland. Lady Fleming became a governess to the infant queen, also born in 1542, and the dowager queen,
Mary of Guise, chose Lady Fleming's daughter Mary to be one of four companions to the young queen. Mary Fleming and Mary, Queen of Scots, were first cousins.
In France In 1548, five-year-old Mary Fleming and her mother accompanied Mary, Queen of Scots, to the court of King
Henry II of France, where the young queen was raised. Mary Fleming's father having died the previous year in the
Battle of Pinkie, her mother had an affair with the French king, the product of which was a son,
Henri d'Angoulême, born around 1551. In 1554, Mary, Queen of Scots played the
Delphic Sibyl and Mary Fleming was the
Erythraean Sibyl in a masque performed at the
Château de Saint-Germain-en-Laye, written by
Mellin de Saint-Gelais.
Scotland Mary, Queen of Scots, and her companions returned to Scotland in 1561 after the death of
Francis II of France. The English diplomat
Thomas Randolph recorded that the queen was consoled by Mary Fleming when she was disturbed by the discovery of the French poet
Chastelard hiding in her bedchamber. After having "some grief of mind", the queen took Mary to be her "bedfellow". On 26 May 1563 the four women attended Mary at the ceremony of the opening of the
Parliament of Scotland. Thomas Randolph described the procession of "four virgins, maydes, Maries, damoyselles of honor, or the Queen's mignions, cawle [call] them as please your honor, but a fayerrer [fairer] syghte was never seen". During the
twelfth day of Christmas pageant in January 1564, Mary Fleming played the part of queen of the Bean. Thomas Randolph was drawn into the dance, and described the costumes:"The queen of the Bean was that day in a gown of cloth of silver; her head, her neck, her shoulders, the rest of her whole body so be-sett with stones, that more in our whole jewel house were not to be found. The Queen herself that day apparreled in colours white & black, no neither jewel or gold about her that day, but the ring that I brought her from (Queen Elizabeth) hanging at her breast, with a lace of black and white about her neck." On 19 September 1564,
William Kirkcaldy of Grange wrote that the Royal Secretary, William Maitland, was showing an interest in Mary Fleming: "I doubt not but you understand me by now, that our secretary's wife is near dead, and he a suitor to Mrs Fleming, who is as fit for him, as I am to be Pope!" Mary Beaton and Mary Fleming were given German-style fur trimmed gowns or petticoats in November 1564, described in French as two "''pellison d'Allemaingne''". ==Marriage to Maitland==
