Taplow was held as a manor by Asgot, a man of Earl Harold in 1066, and by Roger from Bishop Odo of Bayeux in 1086. It was assessed at 8 hides and 1 virgate, and also had a fishery rendering 1,000 eels, meadow for 1 plough and woodland for 700 pigs. When the bishop forfeited his lands it passed to the Honour of Leicester and the Duchy of Lancaster, which retained the tenancy in chief throughout the Middle Ages. The tenancy passed from Roger to the Bolbecs and the Turvilles, and in 1197 William de Turville and his wife Isabel subinfeudated Taplow to the Priory of Merton, which retained the tenancy until the Dissolution. The advowson to the church was held by Merton Priory until 1271 when a claim to it was made by the Prior of Chalcombe and the intermediary lords, descended from the Turvilles.
