Peter de Valognes, Sheriff of Hertfordshire, held Sheering in demesne in 1086, and before the Conquest the manor was held by 3 free men. It was assessed at 5 hides and 30 acres, with woodland for 100 pigs, 32 acres of meadow and a mill.
It descended with the honour of Benington (Hertfordshire) otherwise known as the Valognes barony, to Peter's son Roger (d.1041-42). Roger had 2 sons; the elder, died c.1158 and the honour passed to the younger, Robert, who lived until 1194. His heir was his daughter, Gunnora, who married Robert Fitzwalter but kept the name of Valognes. Her daughter Christiana inherited and she married William de Mandeville, but died without issue in 1233. The estate was then divided between 3 heiresses. The advowson of the church descended with the manor throughout the middle ages.
