Sir Henry de Grey of Grays Thurrock, Essex, was a favourite courtier of King John of England.


Sir Henry was the son of John de Grey[1] (born Thurrock, Essex, c. 1140 and married c. 1157) and probably a great-grandson of Anchetil de Greye (b. circa 1100) of Rotherfield Greys, a grandson of Domesday baron Anchetil de Greye (c. 1052 – 1086+).


Sir Henry was the progenitor of the considerable number of noble houses bearing the name Grey or Gray; Sir Henry's descendants in the direct male line went on to be ennobled with no less than eighteen peerages, including eleven substantive baronies, a viscountcy, four earldoms (Kent, Tankerville, Stamford and Grey), a marquessate and two dukedoms.

Sir Henry's descendants through the female line are countless but include the Barons Audley, Barons Revelstoke, Barons Northbrook, Barons Howick, Barons Dacre, Barons Willoughby de Eresby, Earl of Lindsey, the Earls of Malmesbury, Earls of Westmoreland, Earls of Essex, Earls of Durham, Earls of Cromer, Earls of Elgin, Earls of Bridgewater, the Earls of Ashburnham, the Marquesses of Lindsey and the Dukes of Somerset and Ancaster, amongst many others.


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.[2] 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.

"In the sixth year of King Richard I., that monarch conferred the manor of Thurrock, in the county of Essex (afterwards called Thurrock Grey), upon Henry de Grey, which grant was confirmed by King John, who vouchsafed, by special charter, to permit the said Henry de Grey to hunt the hare and fox in any land belonging to the crown, save the king's own demense-parks. In the 1st Henry III. he had also a grant of the manor of Grimston, in the county of Nottingham, and having afterwards married Isolda, niece and heiress of Robert Bardolf, shared in the inheritance of his lands. By this lady Henry de Grey has issue,

  • Richard, of whom presently.
  • John, some time justice of Chester, progenitor of the Greys of Wilton, and Greys of Ruthyn.
