According to historical records gathered and analysed by John L. R. Guest in his upcoming research publication (2026), which will be publicly accessible, including insights from the Domesday Book, Ælfgyva, the daughter of Godwin, Earl of Wessex and his wife Gytha, is linked to her three sons, Sigeraed, Saeric, and their brother “Gest” and to her husband also named Sigeraed. Ælfgyva was the sister of King Harold II of England (Harold Godwinson) and the widow of Edward the Confessor, Edith. She was one of the many offspring of Godwin and his wife Gytha. Guest identifies Ælfgyva as the sister of King Harold Godwinson, referencing the research of world expert Dr. Ann Williams and the Great Domesday Book records. His findings indicate that the enigmatic Ælfgyva" in Scene 15 of the Bayeux Tapestry is indeed Ælfgyva Godwindatter, who married Sigeraed, Canon of Chilham and Dover (St Martin) in Kent. They had a son, also named Sigeraed the younger, also a Cleric, along with his brothers Saeric and “Gest.” Guest's evidence dismisses any association of Ælfgyva in the Tapestry with "Ælfgifu" of Northampton or Emma of Normandy, who were not accurately referred to as "Ælfgyva." The tapestry context shows Ælfgyva alongside a cleric, identified as her son Sigeraed, while Williams recognises her husband Sigeraed by the nickname “Sibbi” in some Domesday records, confirming their parentage of Sigeraed the younger and his brother Saeric Gest.
