Mary, Queen of Scots

Born at Linlithgow Palace, West Lothian on 8 December 1542, Mary became Queen of Scots when she was six days old. after her father King James V died of high fever. As Henry VII of England's great-granddaughter, Mary was also next in line to the English throne, after Henry VIII's children. This made her a permanent and lasting threat for the Royals of England. After she had been sent to the French court in 1548 already, Mary was married to the Dauphin, future French King Francis II in 1558. After his death she returned to Scotland in 1561. Her future life, marriages and work are legend and too interesting to just tell it within a few lines; please check her biography at the "Official Royal"-website. Mary was executed at Fotheringhay Castle in Northamptonshire on 8 February 1587, at the age of 44. She was buried in Peterborough Cathedral, but in 1612 her son James VI (of Scotland) and I (of England) had her body exhumed and placed in the vault of King Henry VII's Chapel in Westminster Abbey.

Here you can see the signatures of Mary, Queen of Scots above that of her mother Mary of Guise (1515-60) which is very similar. This becomes even more confusing as Mary of Guise signed Scottish documents on behalf of her daughter while she was Regent, before Mary returned from France.  

The second husband of Mary, Queen of Scots, was Henry Stuart, Earl of Darnley (1545-67). The story of this relationship is full of lies, fake feelings, betrayals and intrigues, and after Mary's secretary and confidant, David Rizzio (who had arranged the marriage) was killed by Scottish noble-men (including Darnley), he was murdered himself the following year.
