William Alington (died 19 October 1446), lord of the manor of both Bottisham and Horseheath, Cambridgeshire, was Speaker of the House of Commons of England, Treasurer of the Exchequer of Ireland, Treasurer of Normandy and High Sheriff of Cambridgeshire and Huntingdonshire.
[2] He married Joan (d.1446),[2] said to have been the daughter of William Burgh and the widow of one Barnes.
Later he served in Normandy and held several high offices, including Treasurer and Receiver-General.
Alington's two sons, William (d. 5 July 1459), of Horseheath, and Robert, of Bottisham, both married daughters of the famous Sir John Argentyne of Great Wymondley Manor, Hertfordshire,[2] by his wife Margaret Calthorpe (1380–1427).
By this marriage William Alington the younger acquired the manor of Wymondley, which was held in Grand Sergeanty by the service of presenting the first cup at the Coronation of Kings of England, which service was performed by the Lords of that Manor into the 20th century.
