and irregular, and are largely rounded where they meet. The plan has, in fact, nothing of the squareness of a Roman work, and the rounding of the angles is quite different. It is probable that the tendency to sharpness in its outline is due to the walls and towers of the work in masonry, which, though now gone, is reported to have been at one time present. Eaton, or Eiton, appears in Domesday as held _in capite_ by the Bishop of Bayeux, but there is no mention of a castle either then or at any later time. The Beauchamps, its later lords, do not there appear as Bedfordshire landowners. In the “Liber Niger,” however, about 1165, Simon de Beauchamp held a barony, under which Hugh de Beauchamp held one knight’s fee. This Hugh was of Eaton. He was the eldest son of Oliver, a cadet of Milo de Beauchamp, of Bedford. Oliver and Hugh were founders of Bismead Priory, in Eaton parish. Hugh was a considerable baron. He was Custos of Rhuddlan Castle 3 Henry II., and, 22 Henry II., one of those who conveyed Henry’s daughter to Palermo, on her marriage with the King of Sicily. He was slain in Palestine, 33 Henry II., and succeeded by Roger, his brother, and he by a third brother, William, whose son John inherited, and, 6 Henry III., was seized of the family manors of Eaton and Sandy. His son was William, living 42 Henry III., father of Ralph, summoned as Lord Beauchamp of Eaton, and who died 21 Edward I., holding one fee in Sandy and Eaton, no doubt that held by Hugh, his ancestor. He held Eaton _in capite_, “per baroniam.” His son, Roger de Beauchamp, of Eaton, was the last summoned. He was aged 21 at his father’s death, and his descendants have not been followed up. 44 Edward III., John de Goldington and Jocosa his wife, John Hemmyngford and others, were seized of a third part of Eaton juxta St. Neots, and half of Sandy. 1 Henry IV., Sandy was held by Katherine, wife of Sir Thomas Engayne; and 1 Edward IV., Lord Zouch had Eaton. Long after the extinction of the barons, the barony remained, and Wyboldeston Manor was held of it by Sir John de Greystock. In the reigns of Henry VIII. and Elizabeth, Eaton was held by the Lords Vaux of Harrowden, who sold it in 1624. They were cadets of Vaux of Gillsland, and are said to have inherited Eaton from the Beauchamps.
