Svein Otto Haraldsson took part in raids on England, followed by invasions following the St Brice's Day Massacre in which King Ethelred II (Aethelred the Unready) ordered the slaughter of all Danes - Sweyn Forkbeard's sister Gunnhilde and her children were said to be among those who died. He launched many attacks in Southern England including the burning of Wallingford in 1006. He returned in 1013, by which time the town was apparently rebuilt, and the town submitted to him. After Ethelred died, Sweyn's  son Cnut became king.

Sir Francis Sykes (1732-1804)

MP for Wallingford from 1782 until his death – lived at Basildon Park although he died before the building was complete – was a "nabob" who amassed a fortune in India while employed by the East India Company. In the section of famine, Piggot’s Political Directory says "One individual, Sir Francis Sykes, originally a shoe-black (happy for the poor inhabitants of Bengal, had he never quitted that obscure harmless station) is supposed to have acquired £200,000. By the above monopoly, by which almost as many Indians are supposed to have perished; so rigidly did they adhere to the purity of their religion, which prohibits, in all cases, the use of animal flesh; nevertheless Sir Francis has been long returned to Europe with his wealth, enjoys unmolested, otium cum dignitate; has a seat in the British senate, boroughs at his command, and has been rewarded, by our cost gracious Sovereign, with the title of Baronet." His son, Francis William Sykes, was MP for Wallingford 1794-1796.
