Later it seems to have passed through obscure descent to the Wynford family, of whom nothing other than their names is recorded. In 1343 the estate was recorded as "a manor house sufficiently built with a certain garden adjoining planted with divers and many apple trees, the whole covering some two acres." The record goes on to record some forty householders all charged to serve their lord as "village blacksmith, drover or domestic servant". This was the highest population the village was to have until the late 20th century. The Sydenhams In 1430 following a legal battle over disputed titles, the Wynfords sold the reversion of the estate to John Stourton (died 1438) of Preston Plucknett in Somerset, 7 times MP for Somerset, in 1419, 1420, December 1421, 1423, 1426, 1429 and 1435. Stourton used it as a dowry for his second daughter Joan Stourton (one of his three daughters and co-heiresses) when in 1434 she married John Sydenham MP, of Combe Sydenham in Somerset. The Sydenham family originated at the manor of Sydenham near Bridgwater, Somerset and were said at one time to have been England's largest landowners, yet their wealth seems to have fluctuated with each generation. John Sydenham as an infant inherited the estate from his grandmother, the original Joan Sydenham (née Stourton). However, Brympton D'Evercy was not the principal family residence at this time. In 1534 John Sydenham made over the house to his son, also, John – having first built the North wing to be his private lodgings for later visits. The new owner John III, was a great landowner bequeathing to each of his many children an estate. This lack of primogeniture proved to be the Sydenham's downfall. John III's successor John IV (died 1585), and his son John V (died 1625) were considerably less wealthy than their forebears, and used the house as their sole residence, the result of which was, despite their comparative penury, they added much to the house. John IV built the present west front thus enlarging the hall, and John V built the large kitchen block. Sir John Posthumous Sydenham ("Posthumous" because born after the death of his father) built the south wing in the 17th century. He married Elizabeth Poulett, a descendant of Sir Amias Paulet, and member of one of Somerset's oldest and most notable families. The Pouletts lived at nearby Hinton House at Hinton St George.
