Soon after the Battle of Agincourt in 1415, Edward Plantagenet, Duke of York and Earl of Rutland, came to hold Diss manor, hundred, and market, together with Hemenhale; and the title of Lord FitzWalter became attached to the estate. It was part of a much larger estate that included Hemenhale and Diss manors, with the hundred of Diss in Norfolk, the manors of Shimpling and Thorne in Suffolk, of Wodeham-Walter (now Woodham Walter), Henham, Leiden (now part of Leaden Roding), Vitring, Dunmow Parva (now Little Dunmow), Burnham (possibly equating to the modern village of Burnham-on-Crouch), Winbush, and Shering (now Sheering) in Essex. Shortly afterwards, the estate was acquired by the Ratcliffe family, who inherited the title of Baron FitzWalter. The Ratcliffe family owned the land until at least 1732, styling themselves Viscounts FitzWalter.
