Question: Who died first, Robert Foliot or Robert de Chesney?
Context: Sibton Abbey, an early Cistercian abbey located near Yoxford, Suffolk, was founded about 1150 by William de Chesney, High Sheriff of Norfolk and Suffolk.  A sister house of Warden Abbey, near Bedford, Bedfordshire, Sibton Abbey was the only Cistercian abbey in East Anglia. Robert Foliot (died 1186) was a medieval Bishop of Hereford in England.  He was a relative of a number of English ecclesiastics, including Gilbert Foliot, one of his predecessors at Hereford.  After serving Alexander, Bishop of Lincoln as a clerk, he became a clerk of Henry of Blois, the Bishop of Winchester and brother of King Stephen of England.  He attended the Council of Reims in 1148, where another relative, Robert de Chesney, was elected as Bishop of Hereford.  Chesney then secured the office of Archdeacon of Oxford for Foliot. Roger de Clifford, 5th Baron de Clifford, ninth Lord Clifford, fifth Baron of Westmoreland (10 July 1333 – 13 July 1389), was the son of Robert de Clifford, 3rd Baron de Clifford (d. 20 May 1344), second son of Robert de Clifford, 1st Baron de Clifford (1273–1314), the founder of the northern branch of the family.  His mother was Isabella (d. 25 July 1362), daughter of Maurice, 2nd Lord Berkeley.  He succeeded his elder brother, Robert de Clifford, 4th Baron de Clifford in 1350, on which day he made proof of his age. Robert de Stafford (known also as Robert of Tosny and Robert de Toeni) ( 1039 – c. 1100) was a Norman nobleman, the builder of Stafford Castle in England.  He is generally said to have been a son of Roger I of Tosny; primary evidence is lacking to determine his parentage, according to Cawley.  Cawley notes that Robert de Stafford is connected to the Tosny family through a charter (not dated) under which "Robertus de Stafford" confirmed donations to Wotton Wawen Abbey, Warwickshire by "avus meus Robertus de Toenio et pater meus Nicolaus de Stafford."  Also "Robertus de Staffordia et Robertus filius meus et hæres" confirmed donations of property to Evesham Monastery by "Rodbertus avus meus...et pater meus Nicholaus" by undated charter. Robert de Chesney (died December 1166) was a medieval English Bishop of Lincoln.  He was the brother of an important royal official, William de Chesney, and the uncle of Gilbert Foliot, successively Bishop of Hereford and Bishop of London.  Educated at Oxford or Paris, Chesney was Archdeacon of Leicester before his election as bishop in December 1148. Domhnall MacNeachdainn was a 15th-century Dean and Bishop of Dunkeld.  He was the nephew of Robert de Cardeny, Bishop of Dunkeld, by Robert's sister, Mairead (Mariota).  The latter was also the mistress of King Robert II of Scotland.  His father was probably a chief of the MacNeachdainn (MacNaughton) kindred.  Domhnall was university trained, and by 1431 had a M. A. and a Doctorate in Decrees.  He had been Dean of Dunkeld since the year 1420.  He was one of the commissioners of the Scottish king at the Council of Basel in 1433.  In 1437, Bishop Robert de Cardeny died and Domhnall the Dean was elected as his replacement.  Domhnall died sometime in the year 1440.  Since Alexander Myln at least it has been thought that he sought confirmation from the Papacy and died "en route", but direct evidence for this is lacking. Deddington Castle was a medieval fortification in the village of Deddington, Oxfordshire.  It was built on a wealthy former Anglo-Saxon estate by Bishop Odo of Bayeux following the Norman conquest of England in 1066.  Odo constructed a large castle with two earthwork baileys and a central motte, intending that the castle administer his property in the region and provide a substantial military base in the event of an Anglo-Saxon revolt.  Odo's estates in England were seized following a failed rebellion against William II in 1088, and Deddington Castle was taken back into royal control.  The Anglo-Norman lord William de Chesney acquired the castle in the 12th century and rebuilt it in stone, raising a stone curtain wall around a new inner bailey, complete with a defensive tower, gatehouse and domestic buildings. Robert de Cardeny was a late 14th and early 15th century Scottish cleric.  He was the son of one John Cardeny, and sister of the royal mistress Mariota de Cardeny.  His early career is obscure.  In 1378-80, King Robert II of Scotland petitioned the Pope for a canonry in the diocese of Moray for one "Robert de Cardun", despite the fact that the latter already held canonries and prebends in the diocese of Dunblane and Dunkeld.  This "Robert de Cardun" was both a member of King Robert's household and a student at the University of Paris.  Robert had graduated at Paris in 1381 as Licentiate.  In 1392 he was a receiver of the "English Nation" at Paris and custodian of the Nation's seal.  In 1394 Robert was still in Paris, now as "Master Robert de Cardeny" William de Chesney (died 1174) was a medieval Anglo-Norman nobleman and sheriff.  Son of landholder in Norfolk, William inherited after the death of his two elder brothers.  He was the founder of Sibton Abbey, as well as a benefactor of other monasteries in England.  In 1157, Chesney acquired the honour of Blythburgh, and was sheriff of Norfolk and Suffolk during the 1150s and 1160s.  On Chesney's death in 1174, he left three unmarried daughters as his heirs. William de Chesney (flourished 1142–1161) was an Anglo-Norman magnate during the reign of King Stephen of England (reigned 1135–1154) and King Henry II of England (reigned 1154–1189).  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.  Chesney's heir was his niece, Matilda, who married Henry fitzGerold.
