Professor Alice Roberts, best known as the presenter of Digging for Britain, picks the wife of two English kings and the mother of two English kings. Queen Emma was born in Normandy and came to England as a diplomatic peaceweaver when she married Aethelred in 1002. Somehow she survived the invasion of the Danes under Swein Forkbeard and married his son, King Canute after Aethelred's death. Together with help from Professor Janina Ramirez - author of Femina - and Patricia Bracewell who has written a trilogy of historical novels based on Emma's life, Alice pieces together an extraordinary life, the richest woman in England, aunt of William the Conqueror, mother of Edward the Confessor.
