French Connection

Mary of Guise (French: Marie de Guise) (22 November 1515 – 11 June 1560) was the Lorraine-born queen consort of Scotland as the second spouse of King James V. She was the mother of Mary, Queen of Scots, and served as regent of Scotland in her daughter's name from 1554 to 1560. She was a member of the powerful House of Guise, which played a prominent role in 16th century French politics. (Courtesy of Wikipedia.)
