Saint Margaret of Scotland- From Wikipedia, the free encyclopedia
Saint Margaret of Scotland (Scots: Saunt Magret, c. 1045 – 16 November 1093), also known as Margaret of Wessex, was an English princess and a Scottish queen. Margaret was sometimes called "The Pearl of Scotland".[1] Born in exile in the Kingdom of Hungary, she was the sister of Edgar Ætheling, the shortly reigned and uncrowned Anglo-Saxon King of England. Margaret and her family returned to the Kingdom of England in 1057, but fled to the Kingdom of Scotland following the Norman conquest of England in 1066. By the end of 1070, Margaret had married King Malcolm III of Scotland, becoming Queen of Scots.
