Question: Which person, who succeeded in 1071 to the Earldom of Hereford, participated in the last serious act of resistance against William in the Norman Conquest?

full_context: Document 1: Roger de Breteuil, 2nd Earl of Hereford: Roger de Breteuil, 2nd Earl of Hereford (1056 – after 1087), succeeded in 1071 to the earldom of Hereford and the English estate of his father, William Fitz-Osbern. He is known to history for his role in the Revolt of the Earls
Document 2: Humphrey de Bohun, 7th Earl of Hereford: Humphrey de Bohun, 7th Earl of Hereford, 6th Earl of Essex, 2nd Earl of Northampton, KG (25 March 1341 – 16 January 1373) was the son of William de Bohun, 1st Earl of Northampton and Elizabeth de Badlesmere, and grandson of Humphrey de Bohun, 4th Earl of Hereford by Elizabeth of Rhuddlan, daughter of King Edward I. He became heir to the Earldom of Hereford after the death of his childless uncle Humphrey de Bohun, 6th Earl of Hereford.
Document 3: Norman invasion of Wales: The Norman invasion of Wales began shortly after the Norman conquest of England under William the Conqueror, who believed England to be his birthright. Initially (1067–1081), the invasion of Wales was not undertaken with the fervor and purpose of the invasion of England. However, a much stronger Norman invasion began in 1081 and by 1094 most of Wales was under the control of William's eldest son, King William II of England. The Welsh greatly disliked the "gratuitously cruel" Normans and by 1101 had regained control of the greater part of their country under the long reign of King Gruffudd ap Cynan, who had been imprisoned by the Normans for twelve years before his escape. Gruffudd had some indirect help from King Magnus III of Norway (Magnus Barefoot) who attacked the Normans briefly off the Isle of Anglesey in northwest Wales near Ynys Seiriol, killing Hugh of Montgomery, 2nd Earl of Shrewsbury and leaving the Normans depleted and demoralized. Magnus went on to take the Orkney Islands, the Hebrides, and the Isle of Man, islands north of Wales and west and north of Scotland and England, in 1098.
Document 4: Eustace de Montaut: Eustace de Montaut, or Monte Alto, Montalt, Monhaut, or FitzNorman (ca. 1027-1112), was a Breton soldier, and later baron, who fought on the side of the Normans in the Norman Conquest of England in 1066 and for his achievements was granted several manors by the new king, William the Conqueror.
Document 5: Revolt of the Earls: The Revolt of the Earls in 1075 was a rebellion of three earls against William I of England (William the Conqueror). It was the last serious act of resistance against William in the Norman Conquest.
Document 6: Hugh de Courtenay, 2nd/10th Earl of Devon: Sir Hugh de Courtenay, 2nd/10th Earl of Devon (12 July 1303 – 2 May 1377), 2nd Baron Courtenay, feudal baron of Okehampton and feudal baron of Plympton, played an important role in the Hundred Years War in the service of King Edward III. His chief seats were Tiverton Castle and Okehampton Castle in Devon. The ordinal number given to the early Courtenay Earls of Devon depends on whether the earldom is deemed a new creation by the letters patent granted 22 February 1334/5 or whether it is deemed a restitution of the old dignity of the de Redvers family. Authorities differ in their opinions, and thus alternative ordinal numbers exist, given here.
Document 7: England in the High Middle Ages: England in the High Middle Ages includes the history of England between the Norman Conquest in 1066 and the death of King John, considered by some to be the last of the Angevin kings of England, in 1216. A disputed succession and victory at the Battle of Hastings led to the conquest of England by William of Normandy in 1066. This linked the crown of England with possessions in France and brought a new aristocracy to the country that dominated landholding, government and the church. They brought with them the French language and maintained their rule through a system of castles and the introduction of a feudal system of landholding. By the time of William's death in 1087, England formed the largest part of an Anglo-Norman empire, ruled by nobles with landholdings across England, Normandy and Wales. William's sons disputed succession to his lands, with William II emerging as ruler of England and much of Normandy. On his death in 1100 his younger brother claimed the throne as Henry I and defeated his brother Robert to reunite England and Normandy. Henry was a ruthless yet effective king, but after the death of his only male heir in the White Ship tragedy, he persuaded his barons to recognise his daughter Matilda as heir. When Henry died in 1135 her cousin Stephen of Blois had himself proclaimed king, leading to a civil war known as The Anarchy. Eventually Stephen recognised Matilda's son Henry as his heir and when Stephen died in 1154, he succeeded as Henry II.
Document 8: Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II. When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters. Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king. In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
Document 9: Roger de Leybourne: Sir Roger de Leybourne (1215–1271) was an English soldier and landowner. He was the son of another Sir Roger de Leybourne and his wife Eleanor, the daughter and heir of Stephen of Thornham. In 1199 when the elder Roger was still a minor his wardship was sold to Thornham for 300 marks. The elder Roger then joined the rebels at the start of the First Barons' War in 1215, being captured in November at the siege of Rochester Castle, paying 250 marks for his release. After the death of the elder Roger some time before 1251 his son William de Leybourne inherited seven Knight's fees in Kent and Oxfordshire, as well as substantial debts, which were only cancelled in 1253 by Henry III.

A descendant of Rollo, he was Duke of Normandy (as Duke William II) from 1035 onward. After a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands and by difficulties with his eldest son.
Document 12: Edward the Confessor: Edward the Confessor (Old English: "Ēadƿeard Andettere" ] , Latin: "Eduardus Confessor" ] ; c. 1003 – 5 January 1066), also known as Saint Edward the Confessor, was among the last Anglo-Saxon kings of England. Usually considered the last king of the House of Wessex, he ruled from 1042 to 1066.

He was the second son of Eozen Penteur (also known as Eudon, Eudo or Odo, Count of Penthièvre) by Orguen Kernev (also known as Agnes of Cornouaille).

He was also an active participant in the Welsh Wars and maintained for several years a private feud with the earl of Gloucester. His father, Humphrey (V) de Bohun, fought on the side of the rebellious barons in the Barons' War. When Humphrey (V) predeceased his father, Humphrey (VI) became heir to his grandfather, Humphrey (IV). At Humphrey (IV)'s death in 1275, Humphrey (VI) inherited the earldoms of Hereford and Essex. He also inherited major possessions in the Welsh Marches from his mother, Eleanor de Braose.
