Gunnor in the context of Roger de Montgomerie, 1st Earl of Shrewsbury

Emma of Normandy (referred to as Ælfgifu in royal documents; c. 984 – 6 March 1052) was a Norman-born noblewoman who became the English, Danish, and Norwegian Queen through her marriages to the Anglo-Saxon King Æthelred the Unready and the Danish King Cnut the Great. A daughter of the Norman ruler Richard the Fearless and Gunnor, she was Queen of England during her marriage to King Æthelred from 1002 to 1016, except during a brief interruption in 1013–14 when the Danish King Sweyn Forkbeard occupied the English throne. Æthelred died in 1016, and Emma married Sweyn's son Cnut. As Cnut's wife, she was Queen of England from their marriage in 1017, Queen of Denmark from 1018, and Queen of Norway from 1028 until Cnut died in 1035.

After Cnut's death, Emma continued to participate in politics during the reigns of her sons by each husband, Harthacnut and Edward the Confessor. In 1035 when her second husband Cnut died and was succeeded by their son Harthacnut, who was in Denmark at the time, Emma was designated to act as his regent until his return, which she did in rivalry with Harold Harefoot. Emma is the central figure within the Encomium Emmae Reginae, a critical source for the history of early-11th-century English politics. As Catherine Karkov notes, Emma is one of the most visually represented early medieval queens.

Roger de Montgomery (died 1094), also known as Roger the Great, was the first Earl of Shrewsbury, and Earl of Arundel, in Sussex. His father was Roger de Montgomery, seigneur of Montgomery, a member of the House of Montgomery, and was probably a grandnephew of the Duchess Gunnor, wife of Duke Richard I of Normandy, the great-grandfather of William the Conqueror. The elder Roger had large landholdings in central Normandy, chiefly in the valley of the River Dives, which the younger Roger inherited.
