Question: Margaret Bryan was the Lady Governess to which King of England?
Context: Margaret Bryan (fl.  1815) was a British natural philosopher and educator, and the author of standard scientific textbooks. Margaret Bryan, Baroness Bryan (c. 1468 – c. 1551/52) was Lady Governess to Henry VIII's children: Princess Mary, Princess Elizabeth, Henry FitzRoy and Prince Edward.  The position of Lady Governess in her day resembled less that of the popular modern idea of a governess, more that of a nanny. Edward VI (12 October 1537 – 6 July 1553) was King of England and Ireland from 28 January 1547 until his death.  He was crowned on 20 February at the age of nine.  The son of Henry VIII and Jane Seymour, Edward was England's first monarch to be raised as a Protestant.  During his reign, the realm was governed by a Regency Council because he never reached his majority.  The Council was first led by his uncle Edward Seymour, 1st Duke of Somerset (1547–1549), and then by John Dudley, 1st Earl of Warwick, from 1551 Duke of Northumberland. Sarojini Naidu Medical College (SNMC), is one of the three oldest medical schools of India.  It is located in Agra, Uttar Pradesh state.  It is named after the first lady Governess of Uttar Pradesh, poet and freedom fighter, Bharat Kokila Smt.  Sarojini Naidu. Dr. Margaret Bryan Davis ("née" Margaret Bryan; born October 23, 1931) is an American palynologist and paleoecologist, who used pollen data to study the vegetation history of the past 21,000 years (i.e. since the last ice age) and showed conclusively how temperate-forest species migrated at different rates and in different directions while forming a changing mosaic of communities.  Early in her career, she challenged the standard methods and prevailing interpretations of the data and fostered rigorous analysis in palynology.  As a leading figure in ecology and paleoecology, she served as president of the Ecological Society of America and the American Quaternary Association and as chair of the Department of Ecology, Evolution and Behavior at the University of Minnesota.  In 1982 she was elected to the National Academy of Sciences. Jane Brennan is an Irish actress.  Primarily known for her work on the stage, she played Mary Lacey in the Academy Award-nominated film "Brooklyn".  She also had a recurring role as Lady Margaret Bryan on the series "The Tudors".  She is the co-founder of the Bespoke Theatre Company. Joan Vaux (c. 1463 – 4 September 1538), also known as Mother Guildford, was an English aristocratic woman who was the Lady Governess to the Princesses Margaret Tudor and Mary Tudor, and accompanied the latter to France when she married King Louis XII in 1514. The King and I is the fifth musical by the team of composer Richard Rodgers and dramatist Oscar Hammerstein II.  It is based on Margaret Landon's novel, "Anna and the King of Siam" (1944), which is in turn derived from the memoirs of Anna Leonowens, governess to the children of King Mongkut of Siam in the early 1860s.  The musical's plot relates the experiences of Anna, a British schoolteacher hired as part of the King's drive to modernize his country.  The relationship between the King and Anna is marked by conflict through much of the piece, as well as by a love to which neither can admit.  The musical premiered on March 29, 1951, at Broadway's St. James Theatre.  It ran for nearly three years, making it the fourth longest-running Broadway musical in history at the time, and has had many tours and revivals. Charlotte de La Motte Houdancourt, Duchess of Ventadour (Charlotte Eléonore Madeleine; 1654–1744) was the governess of King Louis XV of France, great-grandson of King Louis XIV.  She is credited with saving Louis XV from the ministrations of the royal doctors when he was ill as a child.  She was the "Gouvernante des enfants royaux", Governess of the Children of France like her mother, granddaughter, granddaughter in law and great grand daughter. Emmeline Lott was the author of "The English Governess in Egypt: Harem Life in Egypt and Constantinople" (1867) an account of her employment as governess to the young son of Isma'il Pasha, Viceroy of Egypt.  Lott believed that her position as a "humble individual" and member of the household provided her with a more authentic perspective than that of aristocratic visitors such as Lady Mary Wortley Montagu, for whom the harem was tidied up for public viewing.  Lott's tone towards Egyptian women is often contemptuous - she claims that far from being Oriental beauties of European fantasy, they are "hideous and hag-like".  Lott believed herself to be superior to Egyptians by virtue of her race; it was a shock to find that as a governess, she was treated as a servant and a social inferior.
