Chesney was part of a large family; one of his brothers became Bishop of Lincoln and another Abbot of Evesham Abbey. Stephen may have named him Sheriff of Oxfordshire. Besides his administrative offices, Chesney controlled a number of royal castles, and served Stephen during some of the king's English military campaigns.
