Lady Janet StewartFrom Wikipedia, the free encyclopediaLady Janet Stewart (c.1505 – c.1563) was an illegitimate daughter of King James IV of Scotland. Her mother was probably Agnes Stewart, herself an illegitimate daughter of James Stewart, 1st Earl of Buchan, but may have been Isobel Stewart, the earl's legitimate daughter.Lady Janet married Malcolm Fleming, 3rd Lord Fleming, who was killed at the Battle of Pinkie in 1547. She became a governess to the infant Queen Mary I of Scotland (aka Mary Queen of Scots 1542-1587), and her own daughter, Mary Fleming, became a lady-in-waiting. They accompanied the young queen to France in 1548, and there Lady Janet became one of the mistresses of King Henry II of France and had an illegitimate son by him. After the child's birth, she was sent back to Scotland.Her son Henri de Valois (1551- June 1586) was legitimated and became governor of Provence.
