dmund was the son of Malcolm III, King of Scotland by his second wife Margaret (daughter of Edgar the Exile). He is supposed to have shared the rule of Scotland with his uncle Donald III. This came about after a rebelion against Donald by Edmund and half-brother Duncan. When Donald succeeded to the throne after the death of Malcolm III, Duncan, Edmund and his other brothers had escaped to the court of the English King William Rufus. With help from the Norman barons, Duncan and Edmund retook the Scottish throne in May of 1094 and Duncan became King. But his reign
was short-lived and Donald retook the Scottish throne in November of the same year when Duncan was killed. After this event Edmund sided with King Donald and, as Donald had no children, was nominated as the heir to the Scottish throne. In 1097 Edgar the Aethling, Margaret's brother, invaded Scotland and placed his nephew Edgar, the younger brother of Edmund, on the Scottish throne. Although details are few, Edmund is thought to have become a monk at Montucute Abbey
were it is believed that he died.
