Marchaunt witnessed deeds at Rye in 1399 and 1411, and in the meantime, in May 1408, he took on a lease for ten years from St. Mary’s chantry there of all its property in the neighbouring village of Iden.
Besides his farming concerns, Marchaunt established a reputation for himself among the gentry of Sussex and Kent as a competent and trustworthy feoffee-to-uses. Thus, in 1392 he acted for John Leigh of Kenardington as trustee of lands in Kent, and in 1401 Paul Marchaunt (probably a kinsman of his) enfeoffed him of property at Playden. More important, also in 1401, Sir William Brenchesle, j.c.p., entrusted him with his estates in both counties; and later on, in November 1405, he was made a feoffee of the manors in Warwickshire and elsewhere which the influential King’s knight Sir John Dallingridge of Bodiam castle had acquired by marriage. Marchaunt’s connexion with Dallingridge was particularly close, for in 1407 Sir John named him as one of his executors. As such, he became involved in settling Dallingridge’s accounts with the Exchequer for custodianship of the Despenser and Mowbray estates in Sussex, granted to the deceased by Henry IV, and in November 1421 he paid over a ‘great and notable’ sum of money to Robertsbridge abbey for masses for Dallingridge’s soul.
Marchaunt made his will on 10 Mar. 1423. His legacies to churches included not only one to Iden church, where he was to be buried, but also to those of Hawkhurst, Playden, Stone and Rye, and to the friaries of Rye and Winchelsea. He also left the church at Iden 50s. towards having it paved, and for building a new pulpit and Easter sepulchre. Masses were to be said for his soul and the souls of his first wife and her father. Besides bequeathing gowns, sheep and money to his servants and friends, he left five marks to William Bernes ‘the man whom he trusted most’. Bernes had been a fellow executor to Sir John Dallingridge, and Marchaunt now made him his own executor too, in association with his wife, Alice, and son, John. He died before 3 Mar. 1424, when the will was proved.
