(Link) The 5th Baron Grey of Rotherfield, another John de Grey, also fought in the Hundred Years War for Edward III, and his splendid brass, dating 1387, can be seen in the lovely Rotherfield Greys Church, hidden beneath a carpet.

(Link) In several books on monumental brasses, the brass in St Nicholas Church at Rotherfield Greys, is identified as that of Sir Robert de Grey (1387). However, a website devoted to the history of the de Grey family, identifies it as follows: "The 5th Baron Grey of Rotherfield, another John de Grey, also fought in the Hundred Years War for Edward III, and his splendid brass, dating 1387, can be seen in the lovely Rotherfield Greys Church, hidden beneath a carpet."
