{"input": "Who is the paternal grandfather of Thomas Beaufort, Count Of Perche?", "context": "Passage 1:\nRotrou III, Count of Perche\nRotrou III (bef. 1080 \u2013 8 May 1144), called the Great (le Grand), was the Count of Perche and Mortagne from 1099. He was the son of Geoffrey II, Count of Perche, and Beatrix de Ramerupt, daughter of Hilduin IV, Count of Montdidier. He was a notable Crusader and a participant in the Reconquista in eastern Spain, even ruling the city of Tudela in Navarre from 1123 to 1131. He is commonly credited with introducing Arabian horses to the Perche, giving rise to the Percheron breed. By his creation of a monastery at La Trappe in memory of his wife, Matilda, daughter of Henry I of England, in 1122 he also laid the foundations of the later Trappists.\n\nFirst Crusade\nRotrou took part in the First Crusade, travelling with the army of the duke of Normandy, Robert Curthose. What influenced Rotrou in this regard were probably familial connexions. He was related to the Anglo-Norman aristocracy and the Perche was a march (border region) in southern Normandy. A sister was married to Raymond I of Turenne, who was a fellow Crusader in the following of Raymond IV of Toulouse. His mother, Beatrix, was a sister of Ebles II of Roucy, who had campaigned in Spain in 1073, and Felicia, who married Sancho Ram\u00edrez, King of Aragon. A religious motivation cannot be discounted.\nAccording to the Chanson d'Antioche, Rotrou was under the command of Bohemond of Taranto during the Siege of Antioch, and was one of the first to go over the city's walls through scaling ladders on 3 June 1098. When the Crusaders had to confront a Seljuk relief force two weeks later in open battle, Rotrou was one of the front line commanders. He fulfilled his vow and made it all the way to Jerusalem. The Chanson also mentions his bravery at the siege of Nicaea of 1097.\nIn 1107, Rotrou built a castle on land held partly allodially and partly in lordship by Hugh II of Le Puiset, thus challenging Hugh's rights to the estate. Since Pope Urban II had taken Crusaders' \"houses, families, and all their goods into the protection of Saint Peter and the Roman church\", and both Hugh and Rotrou were veterans of the First Crusade, the dispute was intractable. Bishop and lawyer Ivo of Chartres could not resolve it, since it involved a judicial duel, over which the church was not allowed to preside, and so remitted it to the court of the County of Blois. There Hugh lost, but in the violence that followed his tenant, who held the land from him as a fief, was captured by Rotrou's men. The reigning pope, Paschal II, who was in Chartres in April, sent the case back to Ivo, who complained in a letter that since \"this law of the Church protecting the goods of knights going to Jerusalem was new. . . they did not know whether the protection applied only to their properties or also applied to their fortifications.\" Rotrou denied that the case had anything to do with the novel canon law.\n\nNorman politics\nDuring Rotrou's absence his father, Geoffrey of Mortagne, died in 1099. On the first Sunday after returning to France, Rotrou paid a visit to the monastery of Nogent-le-Rotrou, a foundation of his family's and the location of his father tomb. There he asked to become a confrater (brother) of the Abbey of Cluny, Nogent's mother house, and to show his sincerity and prove the fulfillment of his Crusading vow he placed a charter confirming his predecessors' donations to the abbey and the palm frond brought back from Jerusalem on the altar.Rotrou's position in the Duchy of Normandy was that of defender of the frontier with the \u00cele-de-France. His position was probably enhanced by his participation in the First Crusade. Whereas his father had only held the title of viscount, Rotrou is usually called a count. In the war between Henry I of England and Robert Curthose, Rotrou sided with the former and was an important figure in Henry's administration of the duchy after the capture of Robert at Tinchebrai in 1106. Rotrou was a direct vassal of Henry in England, where he held fiefs jure uxoris, in right of his wife, the king's daughter Matilda. He was not often in England, but is purported to have been close to his wife.\n\nReconquista\nEarly participation\nRotrou's actual first participation in the Reconquista dates to the first decade of the twelfth century (possibly 1104\u20135). He and a group of Normans are said to have fought the Muslims in the service of Alfonso the Battler, then King of Aragon and Navarre, until the Aragonese plotted against them and they returned home. It has been speculated that the Norman involvement in the campaign originated as gossip designed to discredit Alfonso by Cluny, an ally of Alfonso's rival, Alfonso VI of Castile. More probably the Normans just accomplished too little to be noticed, or were perhaps sent back home without encountering any Muslims because their services were not need at the time, when Alfonso the Battler had an alliance with the taifa (faction-kingdom) of Zaragoza. Perhaps the 'Aragonese plot' originated as a rumour with dissatisfied returning Normans.\nAfter the death of his wife, eldest son and two of his nephews in the wreck of the White Ship (1120), Rotrou returned to Spain. His parting may have been an act of penitence (perhaps he believed his sins had brought on the tragedy), or perhaps a public demonstration of grieving, since his wife was a daughter of the king, who had also lost his heir, William Adelin, in the wreck. According to the Chronicle of San Juan de la Pe\u00f1a, Rotrou took part in the conquests of Zaragoza (1118) and Tudela (1119), but this account has been shown to be apocryphal. Many French barons can be connected with the expedition against Zaragoza, but although his Anales de la Corona de Arag\u00f3n name Rotrou as fighting under Alfonso of Aragon on several occasions, Jer\u00f3nimo Zurita does not mention him by name when recording the call for transpyrenean assistance put out by the Battler. Likewise Rotrou is attested fighting for Henry I in Normandy in 1119 and so could not have had any hand in the conquest of Tudela, although the Chronicle of San Juan makes him out to be the chief conqueror and the first and independent ruler of the town. Neither is he mentioned in the charter of surrender of Tudela.\n\nRule of Tudela\nRotrou was still in Normandy in 1120 when he signed the reconfirmation act of the abbey of Arcisses. Since he received land in Zaragoza after the conquest, it might be assumed that he sent either money or men to assist in the enterprise. He did not sign the city's fueros, which the nobles of southern France who had participated in its conquest did. He had arrived in Aragon by 1123, perhaps as early as 1121. His first participation was probably in the campaign against Lleida. An Aragonese charter dating to April 1123 refers to Rotrou as \"count in Tudela\", although it does not specifically refer to him as the ruler of the place. The Norman lord Robert Burdet, who later held the Tarragona as a principality, may originally have fought alongside Rotrou in Normandy and then followed him to Spain c.1123. Robert is first mentioned in a charter issued by Rotrou in Spain, in which the count granted some houses in Zaragoza to a knight of his named Sabino in gratitude for his services (December 1124). There is a slightly later reference which shows that Rotrou was in control of Tudela and that he had appointed Robert to act as his alcalde (mayor) or military commander of the citadel and one Duran Pixon to act as administrator (justiciar). This charter also affirms, against the Chronicle of San Juan, that Rotrou ruled Tudela as a vassal of Alfonso the Battler, who is called \"emperor\" in the document. Similar charters from February 1128 and November 1131 show that this arrangement continued for almost a decade, even though Rotrou was often absent in Normandy and Robert Burdet in Tarragona. When Alfonso granted fueros to Tudela in 1127 he also mentioned Rotrou, Robert and Duran. It has been suggested that Rotrou's rise to an important frontier post in a city in whose conquest he played no role was either recompense for the mistreatment he received in the first decade of the century or due to the deterrent effect of his private army of Normans on the neighbouring Muslims.In the winter of 1124\u201325, Rotrou led an expedition against the hilltop Muslim fortress of Pe\u00f1a Cadiella (Benicadell), which guarded the road from Alicante to Valencia. Since Muslim troops from Murcia often moved up this road to Valencia, it was of great strategic importance for any planned campaign in eastern al-Andalus. Rotrou's expedition, which had royal approval, may have been planned in conjunction with Alfonso's Andalusian expedition that took place in 1127\u201328. Rotrou was assisted in his endeavour by the Aragonese knights of the Confraternity of Belchite and their master, Galindo S\u00e1nchez. Rotrou returned to Normandy with his retinue in 1125, leaving Robert Burdet in command of Tudela (where he is attested in charters from 1126 through 1128). Rotrou did not participate in Alfonso's Andalusian campaign, and a rumour in Normandy claimed that Alfonso made his war out of envy for Rotrou's achievements.\nRotrou returned to Alfonso the Battler in 1130, when he was at the Siege of Bayonne. On 26 October, from the siege, Alfonso granted the fuero previously given to Tudela to the small town of Corella. Rotrou was one of the signatories, since the castle of Corella had been granted to him by the king in December 1128. He is last attested as ruler in Tudela with Robert as his underling in a private act of November 1131. He was still in Iberia in March 1132, when he witnessed Alfonso's grant of a fuero to the town of As\u00edn.\n\nSecond trip to the Holy Land\nSometime before 1144, Rotrou returned to the Mideast on Crusade, one of the few north French barons to do so. On this second trip Rotrou obtained some relics which he donated to the monastery he had founded at La Trappe.\nIn Spain, Rotrou established links with Garc\u00eda Ram\u00edrez, the future king of Navarre. Garc\u00eda married Margaret of L'Aigle, daughter of Rotrou's sister Juliana. Margaret's daughter Margaret, married William I of Sicily and raised to the chancellorship her cousin Stephen du Perche, a younger and illegitimate son of Rotrou. She also made Gilbert, another cousin from the Perche, count in Gravina. This Gilbert was one of Rotrou's grandsons, although by which son is not known. Another relation, Henry of Montescaglioso, was a son of Margaret, perhaps illegitimate.\n\nFamily\n\nRotrou's first wife's name is unknown.  They had one daughter:\nBeatrix, married Renaud IV, lord of Ch\u00e2teau-GontierRotrou's second wife was Matilda, illegitimate daughter of Henry I of England and one of his many mistresses, Edith. Matilda drowned in the wreck of the White Ship on 25 November 1120.  They had two daughters:\n\nPhilippa, married Elias II, Count of Maine\nFeliciaRotrou's third wife was Hawise, daughter of Walter of Salisbury and sister of Patrick, Earl of Salisbury. They had three sons:\n\nRotrou IV, killed at the Siege of Acre\nGeoffrey (died after 1154)\nStephen, Archbishop of PalermoRotrou also had an illegitimate son by an unknown mistress:\n\nBertrand, father of Gilbert, Count of GravinaRotrou was succeeded as Count of Perche by his son of the same name.\n\n\n== Notes ==\nPassage 2:\nThomas Beaufort, Count of Perche\nThomas Beaufort, styled 1st Count of Perche (c. 1405 \u2013 3 October 1431) was a member of the Beaufort family and an English commander during the Hundred Years' War.\nHe was the third son of John Beaufort, 1st Earl of Somerset and his wife, Margaret Holland.\n\nCareer\nWith his elder brother, Henry Beaufort, 2nd Earl of Somerset, Thomas joined in Henry V's 1419 campaigns in France.  In 1421, he accompanied the king's younger brother Thomas of Lancaster to the fighting in Anjou.  Lancaster was killed at the Battle of Baug\u00e9 while John Beaufort, the new Earl of Somerset (following the death of Henry Beaufort, 2nd Earl of Somerset at the  Siege of Rouen) and Thomas were captured. Thomas was eventually released around 1427 in a prisoner exchange negotiated by his uncle, Cardinal Beaufort.\nAs an able male member of the Beaufort family, Thomas rejoined the fighting almost immediately. He was granted the title Count of Perche in December 1427, his title being more a claim to land, rather than a recognized title since it was already held by the French Duke John II of Alen\u00e7on. This was part of a continuing attempt by Cardinal Beaufort to carve out estates for his nephews from conquered French land. During the 1430 royal coronation expedition of Henry VI, Thomas was granted a retinue of 128 soldiers and 460 archers. He commanded soldiers at a battle at La Charit\u00e9-sur-Loire in late 1430 and died 3 October 1431 at the siege of Louviers, three weeks before the city's fall.\n\nArms\nAs the legitimised great-grandson of Edward III he bore his arms altered by a bordure gorbony argent and azure.\n\nAncestry\nNotes\nPassage 3:\nRotrou IV, Count of Perche\nRotrou IV (1135-1191), was the Count of Perche. He joined Louis VII of France in a war against Henry II of England, in which he lost lands to the English. Rotrou later went on crusade with Philip II of France and died after the Siege of Acre in 1191.\n\nBiography\nBorn in 1135, Rotrou was the son of Rotrou III, Count of Perche, and Hawise, daughter of Walter of Salisbury, and Sibilla de Chaworth. \nUpon the death of his father in 1144, Rotrou continued the fight against his archenemy, William III Talvas, Count of Ponthieu and Lord of Alen\u00e7on. Aside from this long-running blood feud, his uncle Patrick had married William Talvas' daughter Adela. His mother Hawise and her second husband, Robert I of Dreux, served as regents at Perche until he reached the age of maturity.\nRotrou aided Louis VII the Younger against Henry II of England in an ineffective war that saw their troops routed, lands ravaged and property stolen. He was forced to yield the communes of Moulins and Bonsmoulins to the crown England. Nevertheless, a matrimonial alliance with the House of Blois consolidated the declining power of the Counts of Perche.\nIn 1189,  Rotrou joined Philip II of France and Richard I the Lionheart in the Third Crusade. He died sometime after the Siege of Acre in 1191.\n\nMarriage and issue\nIn 1160, Rotrou married Matilda of Blois-Champagne, daughter of Theobald II, Count of Champagne, and Matilda of Carinthia.Rotrou and Matilda had:\n\nGeoffrey III, Count of Perche\nStephen (d. 14 April 1205), Duke of Philadelphia, killed in the Battle of Adrianople\nRotrou du Perche (d. 10 December 1201), Bishop of Chalons (1190-1200)\nWilliam II, Count of Perche and Bishop of Chalons\nBeatrix, married Renaud III, lord of Chateau-GonthierRotrou was succeeded as Count of Perche by his son Geoffrey upon his death.\nPassage 4:\nGeoffrey II, Count of Perche\nGeoffrey II (died October 1100), Count of Mortagne and Count of Perche, was the son of Rotrou I, Viscount of Ch\u00e2teaudun, and Adelise de Bell\u00eame, daughter of Gu\u00e9rin de Domfron. Geoffrey was Count of Mortagne and Seigneur of Nogent from 1060 to 1090, and Count of Perche from 1090 until his death.\nAs a young man, Geoffrey participated in the conquest of England and fought at the Battle of Hastings. For his service, William the Conqueror gave him a reward of significant property in England.Geoffrey succeeded his father in 1080, receiving the Percheron fields (Mortagne-au-Perche and Nogent-le-Rotrou), while his younger brother Hugues received Ch\u00e2teaudun. A third brother, Rotrou, acquired by marriage the lordship of Montfort-le-Rotrou. One of his first actions as count was to hand over the monastery of Nogent-le-Rotrou to Cluny, after engineering the deposition of its abbot Hubert. As a result, the role of the count's court an increased role, since disputes about the abbey's endowment were solved at that court.  About 1089, Geoffrey waged war on Robert of Bell\u00eame, due to a land dispute. According to Orderic Vitalis, Geoffrey contested the distribution of the Belleme inheritance between Mabel de Bell\u00eame (Robert's mother) and Adeliza (his mother).    The war was long and protracted, as even in 1091 we know the conflict was still going on.  He devoted the rest of his life to religious pursuits, and founded the first leper colony in Perche.His successful rule and increased political role can be appreciated from his dynastic alliances, which ranged far into northern France (with his wife Beatrix), Normandy (with the marriage of his daughter Marguerite to Henry de Beaumont) and southern France (through his daughter Matilde's marriage  to the viscount of Turenne). Geoffrey married Beatrix de Ramerupt, daughter of Hilduin IV, Count of Montdidier, and Alice de Roucy.  Geoffrey and Beatrix had:\n\nRotrou III the Great, Count of Perche\nMarguerite (d. after 1156), married to Henry de Beaumont, 1st Earl of Warwick.  Their sons included Roger de Beaumont, 2nd Earl of Warwick, Robert de Neubourg and Rotrou, Archbishop of Rouen.\nJuliana du Perche (d. after 1132), married to Gilbert, Lord of d\u2019Aigle.  They had two sons, Geoffrey and Engenulf, who died in the wreck of the White Ship. Their daughter was Marguerite de l\u2019Aigle, who married Garc\u00eda Ram\u00edrez, King of Navarre.\nMathilde (d. 27 May 1143), married first Raymond I, Vicomte de Turenne and, widowed, Guy IV de Lastours.Orderic Vitalis gives him high praise: In time of peace he was gentle and lovable and conspicuous for his good manners; in times of war, harsh and successful, formidable to the rulers who were his neighbours and an enemy to all. Geoffrey was succeeded by his son Rotrou as Count of Perche upon his death.\n\nNotes\nSources\nBarlow, Frank (1983). William Rufus.

He died young.\nOnly seven when his father died, Thomas became Count of Perche under the regency of his mother and her new husband Enguerrand III, Lord of Coucy.\n\nBiography\nIn 1216, the English barons rebelled in the First Barons' War against King John Lackland, and offered the English crown to Louis VIII the Lion, King of France. The death of King John ended this arrangement and the crown went to Henry III, John's son. In the end, Louis VIII renounced the English crown, but in the interim fought the forces of William Marshal, 1st Earl of Pembroke. In the decisive Battle of Lincoln of 1217, Thomas, the commander of the French forces, was killed.Thomas married H\u00e9lisende Rethel, daughter of Hugh II, Count of Rethel, and Felicitas, daughter of Simon of Broyes. This union produced no children. His widow remarried Garnier de Tra\u00eenel, Seigneur de Marigny.\nFollowing Thomas's death in 1217, King Philip II of France gained control of the castles of Moulins-la-Marche, Bonsmoulin, and Bell\u00eame, which had been contested since 1182. Thomas\u2019s uncle William, who was also Bishop of Ch\u00e2lons, succeeded him as the Count of Perche.\n\nNotes\nPassage 6:\nWilliam II, Count of Perche\nWilliam II (died 1226), count of Perche and bishop of Ch\u00e2lons, son of Count Rotrou IV of Perche and Matilda, daughter of Count Theobald II of Champagne and Matilda of Carinthia.\nWilliam began his career as treasurer and provost of the Church of St. Martin of Tours, and was elected bishop of Chalons in 1215, consecrated in 1216. The following year he became count of Perche upon the death of his nephew Thomas in the Battle of Lincoln. As count-bishop, William was a valuable advisor to the kings of France and was listed among those by Pope Honorious III to participate in the Albigensian Crusade. His death in February 1226 left the question of the succession to the County of Perche unresolved for years. He left money to his cousin Countess Isabelle of Chartres for the \"support of the poor\".\nPassage 7:\nJohn Beaufort, 1st Earl of Somerset\nJohn Beaufort, 1st Marquess of Somerset and 1st Marquess of Dorset, later only 1st Earl of Somerset,  (c. 1373 \u2013 16 March 1410) was an English nobleman and politician. He was the first of the four illegitimate children of John of Gaunt (1340\u20131399) (third surviving son of King Edward III) by his mistress Katherine Swynford, whom he later married in 1396. \nThe Beaufort children were declared legitimate twice by parliament, first during the reign of King Richard II, in 1397, which was confirmed by Henry IV, as well as by Pope Boniface IX in September 1396. Even though they were the grandchildren of Edward III and next in the line of succession after their father's legitimate children by his first two wives, the Beauforts were barred from succession to the throne by their half-brother Henry IV.\n\nEarly life\nBeaufort's surname (properly de Beaufort, \"from Beaufort\") probably reflects his birthplace at his father's castle and manor of Beaufort (\"beautiful stronghold\") in Champagne, France. The Portcullis heraldic badge of the Beauforts, now the emblem of the House of Commons, is believed to have been based on that of the castle of Beaufort, now demolished.\n\nBetween May and September 1390, Beaufort saw military service in North Africa in the Barbary Crusade led by Louis II, Duke of Bourbon. In 1394, he was in Lithuania serving with the Teutonic Knights.John was created Earl of Somerset on 10 February 1397, just a few days after the legitimation of the Beaufort children was recognised by Parliament. The same month, he was also appointed Admiral of the Irish fleet, as well as Constable of Dover Castle and Warden of the Cinque Ports. In May, his admiralty was extended to include the northern fleet. That summer, the new earl became one of the noblemen who helped Richard II free himself from the power of the Lords Appellant. As a reward, he was created Marquess of Somerset and Marquess of Dorset on 29 September, and sometime later that year he was made a Knight of the Garter and appointed Lieutenant of Aquitaine. In addition, two days before his elevation as a Marquess he married the king's niece, Margaret Holland, sister of Thomas Holland, 1st Duke of Surrey, another of the counter-appellants. John remained in the king's favour even after his older half-brother Henry Bolingbroke (later Henry IV) was banished from England in 1398.\n\nLater career\nAfter Richard II was deposed by Henry Bolingbroke in 1399, the new king rescinded the titles that had been given to the counter-appellants, and thus John Beaufort became merely Earl of Somerset again. Nevertheless, he proved loyal to his half-brother's reign, serving in various military commands and on some important diplomatic missions. It was Beaufort who was given the confiscated estates of the Welsh rebel leader Owain Glynd\u0175r in 1400, although he would not have been able to take possession of these estates unless he had lived until after 1415. In 1404, he was named Constable of England.\n\nFamily\nJohn Beaufort and his wife Margaret Holland, the daughter of Thomas Holland, 2nd Earl of Kent and Alice FitzAlan, had six children. His granddaughter Lady Margaret Beaufort married Edmund Tudor, 1st Earl of Richmond, the son of Dowager Queen Catherine of Valois by Owen Tudor.\nJohn Beaufort, 1st Earl of Somerset, died in the Hospital of St Katharine's by the Tower. He was buried in St Michael's Chapel in Canterbury Cathedral.\nHis children included the following:\n\nHenry Beaufort, 2nd Earl of Somerset (1401 \u2013 25 November 1418)\nJohn Beaufort, 1st Duke of Somerset (baptised 25 March 1404 \u2013 27 May 1444) \u2013 father of Margaret Beaufort, Countess of Richmond and Derby, mother of King Henry VII of England\nJoan Beaufort, Queen of Scotland (1404 \u2013 15 July 1445) \u2013 married James I, King of Scots.\nThomas Beaufort, Count of Perche (1405 \u2013 3 October 1431)\nEdmund Beaufort, 2nd Duke of Somerset (1406 \u2013 22 May 1455)\nMargaret Beaufort, Countess of Devon (1409\u20131449) \u2013 married Thomas de Courtenay, 13th Earl of Devon.\n\nAppointments\nLord Warden of the Cinque Ports: 1398\nAdmiral of the West: 1397\nAdmiral of the Irish Fleet: 1397\nLieutenant of Aquitaine: 1397\nAdmiral of the North and Western Fleets: 9 May 1398 \u2013 15 November 1399\nLord High Constable of England: 1404\nAdmiral of the North and Western Fleets: May 1406 \u2013 June 1407\n\nArms\nAs a legitimised grandson of King Edward III, Beaufort bore that king's royal arms, differenced by a bordure gobony argent and azure.\n\n\t\t\n\t\t\nArms of Beaufort, legitimised progeny of John of Gaunt, third surviving son of King Edward III: Royal arms of King Edward III within a bordure compony argent and azure (see Coat of arms of England). The arms were updated when the kings of England adopted France modern, having been adopted by the King of France in 1376. Charles, an illegitimate son of Henry Beaufort, 3rd Duke of Somerset (1436\u20131464), took the surname \"Somerset\" together with the Beaufort arms and was created Baron Herbert (1461) and Earl of Worcester (1513). In 1682 his descendant Henry Somerset, 3rd Marquess of Worcester (1629\u20131700), was created Duke of Beaufort. These arms are thus used by Beaufort, Duke of Somerset (extinct) and Somerset, Duke of Beaufort (extant).\n\nAncestry\nNotes\nPassage 8:\nHenry Krause\nHenry J. \"Red\" Krause, Jr. (August 28, 1913 \u2013 February 20, 1987) was an American football offensive lineman in the National Football League for the Brooklyn Dodgers and the Washington Redskins.  He played college football at St. Louis University.\nPassage 9:\nRotrou I, Viscount of Ch\u00e2teaudun\nRotrou I (born before 1031, died 1079), Viscount of Ch\u00e2teaudun and Count of Perche (as Rotrou II), second son of Geoffrey II, Viscount of Ch\u00e2teaudun, and Helvise de Corbon (d. 1 March 1080), daughter of Rainard, Lord of Pithiviers.\nAt the death of Geoffrey II, his elder son Hugh became Viscount of Ch\u00e2teaudun, while Rotrou probably inherited the family interests around Nogent-le-Rotrou. After his brother's death, he concentrated the family lands and, by the late 1050s, he was a count, with a centre of power around Mortagne.  These northern dominions probably came to him from his wife, Adelise de Domfront, as part of  a settlement that divided the Bell\u00eame inheritance between her cousin Mabel, who married Roger de Montgomery, and Adelise.  \nAfter the death of  William of Gou\u00ebt in the late 1050s, Rotrou, with the help of Roger de Montgomery, tried to extend his influence  for the strongholds of Perche-Gou\u00ebt.  However, William's wife Matilda remarried to Geoffrey, viscount of Mayenne, and was able to fend off the attacks. \nBy 1058, Rotrou was in attendance on King Henry I of France in his attack on the Norman outpost of Thimer. However, by 1066, he had become closer to William, the Norman Duke, which can be inferred from the participation of his son  Geoffrey in the invasion of England.  Moreover, in 1078, William paid Rotrou a subsidy, and Rotrou supported him on the siege of Remalard, where the supporters of his rebel son, Robert Curthose, were concentrated. \nRotrou was quite successful, and able to make substantial donations to religious houses, including St.Vincent of le Mans and his father's foundation of Saint Denis at Nogent-le-Rotrou, where he was able to finish the church.   \nRotrou married Adelise (Adeliza) de Domfront, daughter of Warin de Domfront and granddaughter of William of Bell\u00eame.
