ecclesiastical inquisition was held at Otford Palace to determine the true heirs to the estate (sometime considered a barony) of Eynsford, Kent, following the death, in the archbishop's wardship, of William de Eynsford the 7th lord. It was claimed in two moieties by Nicholas de Crioll and William Herengod. With the extinction of the descent from William the 5th lord (great-grandfather of the deceased) their claim lay in the descent from his sisters Joan, who married Hugh de Auberville (grandfather of Joan, wife of Nicholas) and Beatrice, who by marriage to Stephen Herengod was mother to the co-claimant. This defeated a counter-claim from an elder branch of the family which had never held seisin, and was decided in favour of de Crioll and Herengod. The Second Barons' War In June 1263 the king committed to Nicholas de Crioll the Wardenship of the Cinque Ports, with instructions to Robert de Glastonia, Constable of Dover Castle, to provide him with quarters at the Castle when he should return there. The barons and bailiffs of Dover, Hastings, Romney, Hythe and Sandwich were required "to provide by his counsel two or three of the most approved men for the security and defence of the port[s] by sea and land against any adversaries or rebels." In September 1263 de Crioll received a mandate to take charge of the county of Kent and the Hundred of Middleton in the absence of a Sheriff, and to deliver the issues for munitions to the Constable of Dover. At the death of Hamo de Crevecoeur, Lord of the barony of Chatham and of Leeds Castle, early in 1263, Nicholas is shown to have held five knights' fees from the barony of Folkestone, for which he did service as of the fee of Morteyne. His tenure owed three watches to ward of Dover Castle, and it is recorded that he held from the king in capite by barony elsewhere. Hamo held the Folkestone barony in husband-right of his second wife Matilda de Averenches, Lady of Folkestone, who had died c.1250. John de Criol's son Bertram (the younger) was married to Eleanor de Crevecoeur (third daughter of Hamo and Matilda), who with her sisters inherited the Folkestone barony. The de Crioll family was variously involved in the revolt of 1264. Richard de Clare had died in 1262, reputedly in the house of John de Crioll at Bletchingley, and Sir John himself,
