1543), was one of the "Four Marys" the ladies in waiting to Mary, Queen of Scots who married William Maitland of Lethington Court life Lord Fleming was killed at the Battle of Pinkie in 1547. The following year, presumably due to her unofficial membership in the royal Stewart family, the widow Fleming was appointed governess or nurse to her infant half-niece Mary, Queen of Scots (her new mistress having been fathered by her late half-brother). Her own daughter, Mary Fleming, also joined the queen's household as a lady-in-waiting. In August 1548, mother and daughter accompanied the young queen to France. They waited aboard ship on the Clyde at Dumbarton Castle for a time. Lady Fleming asked Captain Villegaignon if the queen could go back ashore to rest. Villegaignon swore she would go to France or drown on the way. Giovanni Ferrerio wrote to Robert Reid, Bishop of Orkney, concerned about Lady Fleming's lack of French or Latin. As she was only fluent in Scots, he doubted her ability to communicate to French doctors any symptoms of illness seen in Mary. He hoped Reid would speak to Mary of Guise to secure the appointment of a Scottish physician, William Bog. At the royal court of France, Lady Fleming soon attracted the attentions of King Henry II and became his lover. Their affair resulted in pregnancy, and—either before or after bearing the French monarch an illegitimate son—Janet was sent back to Scotland and replaced as governess to Mary by Françoise de Paroy. Her boy, called Henri de Valois-Angoulême (1551–June, 1586), was "the chief and most highly favored natural son of the King". He was legitimized and went on to become the "Grand Prior of France, Governor of Provence, and Admiral of the Levantine Sea." In November 1549 the English prisoner James Wilford was exchanged for the release of her son James, Lord Fleming, who had been captured during the war of the Rough Wooing. In October 1552, Janet's situation in Scotland was described by Mary of Guise in a letter written to her brother, the Cardinal of Lorraine. There had been talk of marrying Janet off to Henri Cleutin, Guise's military advisor. Although one of Janet's daughters had informed Mary of Guise that her mother did not wish to leave Scotland, Guise knew that Janet had discussed leaving Scotland with the Governor, Regent Arran, and wanted to see Henry II that winter.
