Thurstan or Turstin of Bayeux was a medieval Archbishop of York, the son of a priest. He served kings William II and Henry I of England before his election to the see of York in 1114. Once elected, his consecration was delayed for five years while he fought attempts by the Archbishop of Canterbury to assert primacy over York. Eventually, he was consecrated by the pope instead and allowed to return to England. While archbishop, he secured two new suffragan bishops for his province. When Henry I died, Thurstan supported Henry's nephew Stephen of Blois as king. Thurstan also defended the northern part of England from invasion by the Scots, taking a leading part in organising the English forces at the Battle of the Standard (1138). Shortly before his death, Thurstan resigned from his see and took the habit of a Cluniac monk.
Robert of Ghent or Robert de Gant was Lord Chancellor of England and Dean of York in the 12th century. The younger son of a nobleman, Robert was probably a member of the cathedral chapter of York before his selection as chancellor by King Stephen of England in the mid-1140s. He is not mentioned often in documents from his time as chancellor, but why this is so is unknown. He became dean at York Minster around 1147. Robert was slightly involved in the disputes over who would be Archbishop of York in the late 1140s and 1150s, but it is likely that his chancellorship prevented his deeper involvement in diocesan affairs. He was no longer chancellor after the death of Stephen, but probably continued to hold the office of dean until his death around 1157 or 1158.
Henry Murdac was abbot of Fountains Abbey and Archbishop of York in medieval England.
Jocelin of Wells was a medieval Bishop of Bath. He was the brother of Hugh de Wells, who became Bishop of Lincoln. Jocelin became a canon of Wells Cathedral before 1200, and was elected bishop in 1206. During King John of England's dispute with Pope Innocent III, Jocelin at first remained with the king, but after the excommunication of John in late 1209, Jocelin went into exile. He returned to England in 1213, and was mentioned in Magna Carta in 1215.
Alexander of Lincoln was a medieval English Bishop of Lincoln, a member of an important administrative and ecclesiastical family. He was the nephew of Roger of Salisbury, a Bishop of Salisbury and Chancellor of England under King Henry I, and he was also related to Nigel, Bishop of Ely. Educated at Laon, Alexander served in his uncle's diocese as an archdeacon in the early 1120s. Unlike his relatives, he held no office in the government before his appointment as Bishop of Lincoln in 1123. Alexander became a frequent visitor to King Henry's court after his appointment to the episcopate, often witnessing royal documents, and he served as a royal justice in Lincolnshire.
Savaric fitzGeldewin was an Englishman who became Bishop of Bath and Glastonbury in England. Related to his predecessor as well as to Emperor Henry VI, he was elected bishop on the insistence of his predecessor, who urged his election on the cathedral chapter of Bath. While bishop, Savaric spent many years attempting to annexe Glastonbury Abbey as part of his bishopric. Savaric also worked to secure the release of King Richard I of England from captivity, when the king was held by Emperor Henry VI.
John Blund was an English scholastic philosopher, known for his work on the nature of the soul, the Tractatus de anima, one of the first works of western philosophy to make use of the recently translated De Anima by Aristotle and especially the Persian philosopher Avicenna's work on the soul, also called De Anima. He taught at Oxford University along with Edmund of Abingdon. David Knowles said that he was "noteworthy for his knowledge of Avicenna and his rejection of the hylomorphism of Avicebron and the plurality of forms.", although the problem of the plurality of forms as understood by later scholastics was not formulated explicitly in Blund's time. Maurice Powicke calls him the "first English Aristotelian."
Roger Niger was a thirteenth-century cleric who became Bishop of London. He is also known as Saint Roger of Beeleigh.
John of Tours or John de Villula (died 1122) was a medieval Bishop of Wells in England who moved the diocese seat to Bath. He was a native of Tours and was King William I of England's doctor before becoming a bishop.

He rebuilt the church at Bath, building a large cathedral that no longer survives. He gave a large library to his cathedral and received the right to hold a fair in Bath. Not noted for his scholarship, he died suddenly in 1122.

Hamo was a 12th- and 13th-century English cleric. He was the Diocese of York's dean, treasurer, and precentor, as well as the archdeacon of the East Riding. His background is unknown, but he was probably a canon of the cathedral chapter at York Minster by 1171. He claimed to have been treasurer of the chapter by 1189, but did not actually hold the office until 1199. Hamo clashed with his archbishop, Geoffrey several times, and when Geoffrey died, Hamo's fellow canons were forbidden by King John of England from electing Hamo to succeed Geoffrey. Hamo died sometime after 1219, when he was last attested as holding his final office, dean.
