The Heveningham family took its name from the township in east Suffolk where lay its chief residence. By the early 14th century the head of the family was well established among the gentry of East Anglia, holding substantial properties in Essex and Norfolk as well as in his home county. Our Sir John’s father and namesake held manors in Goldhanger, Eastwood and Little Totham besides other premises in Essex, and as parcel of the manor of Little Totham he possessed knights’ fees in Garboldisham and Langford in Norfolk and Willingham in Suffolk. Through that Sir John’s marriage to Joan Gissing, the Heveninghams acquired the Norfolk manors of Roydon and Gissing as well. These estates provided the family with an annual income of at least £75. Sir John senior died in 1375 having settled most of his lands on his wife in jointure, so his son was unable to enter into his full inheritance until his mother’s death 20 years later. John was under age when his father died and, as Little Totham was held in chief for payment of a fixed sum of money for castle-guard at Dover, he was made a royal ward.
Heveningham’s career as a soldier had begun by October 1379 when, already a knight, he obtained royal letters of protection to sail to Brittany in the expeditionary force led by John, Lord Arundel, the marshal. He was fortunate to survive the gales which scattered the fleet and cost Arundel and many others their lives, but the experience may have made him wary of further adventures overseas, and nothing more is heard of military employment. However, in April 1390 he obtained permission to exchange £100 into foreign currency, so it may be that he had decided to venture abroad on a pilgrimage.
Heveningham’s high standing in East Anglia may be gathered from the number of trusteeships he was asked to undertake by important members of the local gentry, but it is worth remarking that, as in the sphere of local government, nearly all of his activity in this respect dated from after 1399. Among those for whom he acted were Robert Bukton, John Wynter, Sir Richard Waldegrave’s heirs, Sir Thomas Gerberge and Sir John Howard. His connexion with the influential Sir Thomas Erpingham may have come about through the latter’s position as constable of Dover castle, a place with which Heveningham had associations owing to the terms of his tenure of Little Totham. He served Erpingham as a feoffee of the estates which later passed to Sir Thomas’s nephew, Sir William Phelip of Dennington.
Sir John completed depositions of his property on 2 Oct. 1424. His main concern was the welfare of his favourite daughter, Margaret, who was to receive 300 marks from the issues of Little Totham for her marriage and, in addition, to enjoy an annuity of £10 for life. She was also to have possession of the manor of Writtle in Essex on the death of Thomas, her uncle. Another daughter, Anne, a nun in Bruisyard abbey, was left an annuity of no more than £2; while a third, the wife of James Andrew, the lawyer, was not mentioned at all. His heir was his eldest son and namesake, but he made provision as well for his other sons, Philip and Thomas. In his will, composed on 19 Aug. 1425, he asked to be buried in Heveningham church, to which he left vestments made of cloth of gold. He died three days later, but for some unknown reason the will was not cleared for probate at Norwich until 1444.
