|Until about 1378, Gaynes remained with the de Havering family, until its acquisition
by Alice Perrers (by 1393). Sir John Deynecourt (a follower of John of Gaunt) held the
manor in by 1400, the year that Alice Perrers died; this is a bit confusing because Alice
Perrers left "her manor of Upminster" in her will to a young niece. This niece
subsequently gave up any rights that she may have had for 40 marks (about 26 pounds, i.e.
not much for 850 acres !) to Roger Deynecourt in 1406. Overall, these transactions
probably represent some legal uncertainty about the true owner of the manor, or, as we
would now say, a possible defect in the title, which was resolved by a small compensation
to the descendants of Alice Perrers.
Roger Deynecourt purcahsed more land in Upminster between 1406-1455, and thus probably
extended the estate to the 1500 acres or so (see Engayne). His
son Thomas held it until death in 1464; his wife may have been called Anne, who remarried
Hugh Cawood; Anne was Lady of the Manor until 1515.
In 1526 Nicholas Wayte purchased the manor from Richard Deyncourt (? nephew of Roger
Deyncourt), but Wayte was the husband of Richard Deyncourt's half-sister Ellen, so it was
still "in the family". Wayte died in 1543, and the manor (then described as of
1000 acres) was sold to Ralph Latham
