In the Middle Ages the manor was held by the Norman Wak, or Wake, family. At Lincoln Assizes on 29 April 1263, Henry, prior of St Katherine’s-without-Lincoln, complained about Baldwin Wake. He said that Baldwin had confiscated his property at Whisby and demanded he "do suit" at his court of Scheldingope every three weeks. Baldwin’s favoured tenant at Whisby was Brian, son of John, and as lord of the manors of Skellingthorpe and Whisby he resented the prior's free tenement of the land. The assizes judged in favour of the prior. Following the Second Barons' War in England, Baldwin's lands – Skellingthorpe, Hykeham, Waddington – were seized by Antony Bek and Alexander de Montfort, who were entrusted by Henry III with confiscating property owned by rebel supporters. In the reign of King Edward I, he was charged with unjustly taking "consuetudines" (customary tolls) from persons passing along the king's highway in Skellingthorpe beyond the limits of his ownership. On 4 January 1283 the manor of "Skeldingho" and all Baldwin's other lands were granted to Edmund, Earl of Cornwall; although Baldwin's widow, Hawisia, and others were allowed their rights as adjudged in the king’s court’.
