Henry de Grey

In 1195 he had been granted the Manor of Thurrock in Essex which later became known as Grays Thurrock (or simply Grays), which he bought from Isaac the Jew and his son Josce. To commemorate this connection, on 11 June 2013 (the 808th anniversary of the charter), a green Thurrock heritage plaque was unveiled to de Grey.^[1] Before 1201 he was also granted the Manor of Codnor, Derbyshire, and in 1216 was also granted by King Henry III of England the Manor of Grimston in Nottinghamshire.
