Question: Who was a soldier that later achieved several manors as a baron from the first Norman King of England?
Context: Lord Thomas de Moulton (1276–1322) was the first Baron Multon of Gilsland.  He married Eleanor de Burgh, daughter of Richard de Burgh 2nd Earl of Ulster; Richard's other daughter, Elizabeth de Burgh, married King Robert the Bruce of Scotland.  On 26 August 1307, Thomas de Moulton was summoned to parliament as Baron Moulton of Gilsland, the only creation of that title in the Peerage of England.  He was engaged in many of the Scottish wars and subsequently obtained many immunities from the crown in the shape of grants for fairs and markets upon his many manors.  He died on 26 November 1313 leaving an only daughter and heiress, Margaret, who inherited the title and estates and was later nicknamed the "Flower of Gillesland".  She married Ranulph (Ralph) de Dacre, whom she married because she found him chivalrous.  Her father originally opposed the match, but relented when he discovered that the Dacre family was equal to his own in wealth and power, according to the Moulton Annals.  Ranulph was later summoned to parliament as Lord Dacre in 1321.  The title and estates after Margaret's death in 1361 were inherited by the Dacre family. William I (c. 1028 – 9 September 1087), usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087.  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. William the conqueror, the first Norman King of England who reigned from 1066 until his death in 1087, created 10 laws for the English people to abide by after the Battle of Hastings. The Liberty of Thomas Court and Donore (also known as the Earl of Meath's Liberty) was one of several manors, or liberties, that existed in County Dublin, Ireland since the arrival of the Anglo-Normans in the 12th century.  They were adjacent to Dublin city, and later entirely surrounded by it, but still preserving their own separate jurisdiction. Peter de Preaux, known in his time in the Old French language as Pierre de Préaux, (died 1212) was a Norman knight in the service of the Angevin kings of England.  Osbert, Peter's father, was a minor Norman baron in the Roumois (the neighborhood of Rouen, the capital of Normandy).  He held the tower and ville of Preaux as well as land at Darnétal.  Osbert also owned a scattering of manors in England.  Peter, as the second son of the sire de Preaux, had few prospects for a landed estate.  He, along with his brothers John, William, and Enguerrand were part of the royal household from a very early age.  Peter would serve in succession, Henry II, Richard I, and John of England.  Peter and William were known throughout the tournament circuit of the day as fierce warriors and competent knights.  Sometime prior to 1189 CE, Osbert had died.  John, the eldest son succeeded him to the family barony. Hugh le Despencer, 2nd Baron le Despencer (1308–1349), Lord of Glamorgan, was the eldest son and heir of Hugh Despenser the Younger and grandson of Hugh le Despenser, 1st Earl of Winchester.  His father and grandfather were both executed in 1326.  His mother was Eleanor de Clare, "suo jure" Lord of Glamorgan, daughter of Gilbert de Clare, 6th Earl of Hertford and Joan of Acre.  Through his mother, Hugh was a great grandson of King Edward I.  He married Elizabeth Montague (d.1359), and both are buried in Tewkesbury Abbey, Gloucestershire, which abbey was founded by Robert Fitzhamon (d.1107), the first Norman feudal baron of Gloucester and Lord of Glamorgan. Robert Fitzhamon (died March 1107), or Robert FitzHamon, Seigneur de Creully in the Calvados region and Torigny in the Manche region of Normandy, was the first Norman feudal baron of Gloucester and the Norman conqueror of Glamorgan, southern Wales.  He became Lord of Glamorgan in 1075. Baron de Clifford is a title in the Peerage of England.  It was created in 1299 for Robert de Clifford ("c."1274–1314), feudal baron of Clifford in Herefordshire, feudal baron of Skipton in Yorkshire and feudal baron of Appleby in Westmoreland.  The title was created by writ, which means that it can descend through both male and female lines.  The Norman family which later took the name "de Clifford" settled in England after the Norman Conquest of 1066 and was first seated in England at Clifford Castle in Herefordshire.  The first Baron served as Earl Marshal of England but was killed at the Battle of Bannockburn in 1314.  His 8th generation descendant the 11th Baron, was created Earl of Cumberland in 1525, whose grandson the 3rd Earl was a noted naval commander.  On the latter's death in 1605 the earldom passed to his younger brother, the 4th Earl (see the Earl of Cumberland for later history of this title). Historically, feudal barons were the king's tenants-in-chief, that is to say men who held land by feudal tenure directly from the king as their sole overlord and were granted by him a legal jurisdiction (court baron) over their territory, the barony, comprising several manors.  Such men, if not already noblemen, were ennobled by obtaining such tenure, and had thenceforth an obligation, upon summons by writ, to attend the king's peripatetic court, the earliest form of Parliament and the House of Lords.  They thus formed the baronage, which later formed a large part of the peerage of England. 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.
