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?

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 <SEP> Earl Coningsby was a title in the Peerage of Great Britain.  It was created in 1719 for Thomas Coningsby, 1st Baron Coningsby, with remainder to his eldest daughter (by his second wife Lady Frances Jones), Margaret Newton, 1st Viscountess Coningsby, and the heirs male of her body.  He was the great-grandson of the soldier and politician Sir Thomas Coningsby.  Coningsby had already been created Baron Coningsby, of Clanbrassil, in the Peerage of Ireland in 1693, with normal remainder to heirs male, and Baron Coningsby in the Peerage of Great Britain in 1716, with similar remainder as for the earldom.  On Lord Coningsby's death in 1729 he was succeeded in the Irish barony of 1692 by his grandson Richard Coningsby, the second Baron, the son of one of Coningsby's sons from his first marriage to Barbara Georges.  However, Richard died already the same year, when the barony became extinct.  Lord Coningsby was succeeded in the English barony and the earldom according to the special remainder by his daughter Margaret Newton, 1st Viscountess Coningsby.  She had already in 1716 been made Baroness Coningsby, of Hampton Court in the County of Hereford, and Viscountess Coningsby in her own right.  Both titles were in the Peerage of Great Britain.  Lady Coningsby was the wife of Sir Michael Newton, 4th Baronet, of Barrs Court (see Newton Baronets).  She had no surviving male issue and the titles became extinct on her death in 1759. <SEP> 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. <SEP> 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.
