Malcolm III was King of Scotland from 1058 to 1093. He was later nicknamed "Canmore". Malcolm's long reign of 35 years preceded the beginning of the Scoto-Norman age. Henry I of England and Eustace III of Boulogne were his sons-in-law, making him the maternal grandfather of Empress Matilda, William Adelin and Matilda of Boulogne. All three of them were prominent in English politics during the 12th century.
