[2] John and William had a sister called Margaret, who was the wife of Haimo de St Clair.
[2] These lands were recorded in the Domesday Book of 1086 as being held by the king, and when Chesney was granted them they were assessed at one knight's fee in feudal service.
[14] In 1153 or 1154, Chesney was the recipient of the lordship of a hundred and a half in Norfolk,[d] possibly in compensation for the loss of the manor of Mileham.
Chesney likely lost Mileham to another noble family, the fitzAlans, as part of the settlement resulting from the Treaty of Wallingford which settled the civil war in England.
[17] The same documents record him as holding the office of Sheriff of Suffolk at concurrent times.
[8] William and Gilla's daughters were Margaret, Clemence, and Sara,[2] all of whom were unmarried at the time of their father's death.
In 1214, his daughter Margaret was exempted from repaying any of her father's debts to those moneylenders by a royal grant.
