The Godmanstons had held their lands in Essex and Dorset for several centuries. Robert de Godmanston† represented Dorset in the Parliament of 1307 and Walter, the MP’s paternal grandfather, was sheriff of Essex and Hertfordshire in 1381-2, but the family was never of the first rank of the gentry. John, probably a lawyer, is rather an obscure figure. In Essex, his county of residence, he inherited a manor at Little Bromley and the moiety of another at Frinton. Like other Essex gentry, he joined the guild of St. Helen at Colchester (in his case, by the early 1440s), but there is no evidence that he held property in that town. In Dorset, he succeeded to two other manors, at Godmanstone (the parish from which his family took its name) and Fifehead Magdalen.
Even if he was not of the first rank of the county gentry, the extent of Godmanstone’s landholdings meant that he comfortably qualified to sit in Parliament as a knight of the shire and ensured that he was distrained for knighthood on at least three occasions. Among his gentry associates in Essex were John Marney, for whom he witnessed a charter in 1443, the Doreward family, for whom he was a feoffee,
Godmanston is first heard of in 1423, when he was party to the settlement of a manor at Canewdon in south-east Essex,
In spite of suffering a prolonged period of ill health, Godmanston saw some of his busiest years as a local administrator during the 1450s. In the wake of Cade’s Rebellion, he served on several ad hoc commissions restoring order in Essex, one of the counties principally affected by the revolt, and he became sheriff of that county and Hertfordshire in 1452. A few months after his term as sheriff expired, he was unable through sickness to present his account in the Exchequer. He was still indisposed in May 1454 when the King ordered the Exchequer to allow him to appear before it in the person of an attorney. In the following autumn, he was excused £180 of his account as sheriff, in recognition of the expenses and losses he had incurred in the office.
Having obtained a pardon in January 1459,
