Notes:

William de Braose (c. 1197 - 2 May 1230) was the son of Reginald de Braose by his first wife, Grecia de Briwere (born 1186) from Stoke in Devon. He was an ill-fated member of a powerful and long lived dynasty of Marcher Lords.

William de Braose was born in Brecon, probably between 1197 and 1204. The Welsh, who detested him and his family name, called him Gwilym Ddu, Black William. He succeeded his father in his various lordships in 1227, including Abergavenny and Builth.

William married Lady Eva Marshal, daughter of William Marshal, 1st Earl of Pembroke. They had four daughters:
Isabella de Braose (born c. 1222), wife of Prince Dafydd ap Llywelyn
Maud de Braose (born c. 1224 - 1301), wife of Roger Mortimer, 1st Baron Wigmore another very powerful Marcher dynasty.
Eleanor de Braose (c. 1226 - 1251), wife of Humphrey de Bohun and mother of Humphrey de Bohun, 3rd Earl of Hereford.
Eve de Braose (c. 1227- July 1255), wife of William de Cantelou.

He was captured by the Welsh forces of Prince Llywelyn the Great, in fighting in the commote of Ceri near Montgomery, in 1228. William was ransomed for the sum of £2,000 and then furthermore made an alliance with Llywelyn, arranging to marry his daughter Isabella de Braose to Llywelyn's only legitimate son Dafydd ap Llywelyn.

However on a later visit to Llywelyn during Easter 1230 William de Braose was found in Llywelyn's private bedchamber with Llywelyn's wife, Joan, Lady of Wales.

The Chronicle of Ystrad Fflur's entry for 1230 reads:
"In this year William de Breos the Younger, lord of Brycheiniog, was hanged by the Lord Llywelyn in Gwynedd, after he had been caught in Llywelyn's chamber with the king of England's daughter, Llywelyn's wife."

Llywelyn had William publicly hanged on 2 May 1230, possibly at Crogen, near Bala. though others believe the hanging took place near Llywelyn's palace at Garth Celyn.

With William's death by hanging and his having four daughters, who divided the de Braose inheritance between them and no male heir, the titles now passed to the junior branch of the de Braose dynasty, the only male heir was now John de Braose who had already inherited the titles of Gower and Bramber from his far-sighted uncle Reginald de Braose.

William's wife Eva continued to hold de Braose lands and castles in her own right, after the death of her husband. She was listed as the holder of Totnes in 1230, and was granted 12 marks to strengthen Hay Castle by King Henry III on the Close Rolls (1234-1237).

William married Eva Marshal Bef 1221. Eva (daughter of William Marshal and Isabel De Clare) was born 1203, Pembrokeshire, Wales; died 1246. [Group Sheet]

Notes:

Reginald de Braose (died June 1228) was one of the sons of William de Braose, 4th Lord of Bramber and Matilda, also known as Maud de St. Valery and Lady de la Haie. Her other children included William and Giles.

The de Braoses were loyal to King Richard I but grew in power under King John of England. The dynasty was in conflict with King John towards the end of his reign and almost lost everything.
Reginald de Braose was a scion of the powerful Marcher family of de Braose, helped manage its survival and was also related by marriage to the Welsh Princes of Wales.

He supported his brother Giles de Braose in his rebellions against King John. Both brothers were active against the King in the Baron's War. Neither was present at the signing of Magna Carta in June 1215 because at this time they were still rebels who refused to compromise.

King John acquiesced to Reginald's claims to the de Braose estates in Wales in May 1216. Reginald became Lord of Brecon, Abergavenny, Builth and held other Marcher Lordships but was also very much a vassal of the Welsh leader Llewelyn Fawr, Prince of Gwynedd who became his father-in-law in 1215 when Reginald married Llywelyn's daughter, Gwladus Ddu, known as Black Gwladys due to her raven hair.

Henry III restored Reginald to favour and the Bramber estates (confiscated by King John) in 1217.

At this seeming betrayal, Rhys and Owain, Reginald's Welsh nephews who were Princes of Deheubarth, were incensed and they took Builth, except the castle. Llywelyn Fawr also became angry and his forces besieged Brecon. Reginald eventually surrendered to Llewelyn and gave up Seinhenydd (Swansea).

By 1221 they were at war again, with Llewelyn again laying siege to Builth. The siege was relieved by King Henry III's forces. From this time on Llewelyn tended to support the claims of Reginald's nephew John de Braose concerning the de Braose lands in Wales.

Reginald was a witness to the re-issue of Magna Carta by King Henry III in 1225.
He died two or three years later in 1227 or 1228 in Brecon and was succeeded by his son by his first wife, Grecia de Briwere, the ill-fated William de Braose, Lord Abergavenny. He is buried at Brecon Cathedral. His daughter Matilda de Braose was the wife of Rhys Mechyll, Prince of Deheubarth.

• Reference Number: 15699

Notes:

William Marshal, 1st Earl of Pembroke (1146 - 14 May 1219), also called William the Marshal (Guillaume le Maréchal), was an Anglo-Norman soldier and statesman. He has been described as the "greatest knight that ever lived" (Stephen Langton). He served four kings - Henry II, Richard the Lionheart, John and Henry III - and rose from obscurity to become a regent of England for the last of the four, and so, one of the most powerful men in Europe. Before him, the hereditary title of "Earl Marshal" designated head of household security for the king of England; by the time he died, people throughout Europe (not just England) referred to him simply as "the Marshal".

Early life

In 1152, when William was probably about six years old, his father John Marshal switched sides during the period of civil war in England often referred to as The Anarchy, The civil war was between King Stephen and Empress Matilda, both whom claimed the Monarchy. According to one chronicler, when King Stephen besieged Newbury Castle, Stephen used the young William as a hostage to ensure that John kept a promise to surrender the castle. John however, used the time alloted to reinforce the castle and alert Matilda's forces. When Stephen ordered John to surrender immediately or watch as he hanged William in front of the castle, John replied that he go ahead, saying "I still have the hammer and the anvil with which to forge still more and better sons!" Fortunately for the child, Stephen could not bring himself to hang young William.

Knight-Errant:

As a younger son of a minor nobleman, William had no lands or fortune to inherit, and had to make his own way in life. As a youth he was sent to Normandy to serve in the household of William de Tancarville, where he began his training to become a knight. Through William de Tancarville, he then served in the household of his mother's brother, Patrick, Earl of Salisbury. In 1168 William's uncle was killed in an ambush by Guy of Lusignan. William was injured and captured in the same battle, but was ransomed by Eleanor of Aquitaine, who was apparently impressed by tales of his bravery. He had been knighted in 1167 and soon found he could make a good living out of winning tournaments. At that time tournaments were dangerous, often deadly, staged battles, not the jousting contests that would come later, and money and valuable prizes could be won by capturing and ransoming opponents. His record is legendary: he supposedly fought in 500 such bouts in his life and never lost once.

Royal favour:

Upon his return William rejoined the court of King Henry II, and now served the father through the many rebellions of his remaining sons (Richard, Geoffrey, and John). In 1189, while covering the flight of Henry II from Le Mans to Chinon, William unhorsed the undutiful Richard in a skirmish. William could have killed the prince but killed his horse instead, to make that point clear. He is said to be the only man ever to unhorse Richard. After Henry's death, he was welcomed at court by his former adversary, now King Richard I, who was not foolish enough to exclude a man whose legend, and power, just kept growing.

In August 1189, when he was 43, King Richard arranged for him to marry the second-richest heiress in England, Isabel de Clare (1172-1220), the 17-year-old daughter of Richard Strongbow. Her father had been Earl of Pembroke, and this title was granted to William, along with large estates in England, Wales, Normandy and Ireland. The marriage transformed the landless knight from a minor family into one of the richest men in the kingdom, a sign of his power and prestige at court. They had five sons and five daughters, and have numerous descendants (see below). William made numerous improvements to his wife's lands, including extensive additions to Pembroke Castle and Chepstow Castle.

William was included in the council of regency which the King appointed on his departure for the Third Crusade in 1190. He took the side of Prince John when the latter expelled the justiciar, William Longchamp, from the kingdom, but he soon discovered that the interests of John were different from those of Richard. Hence in 1193 he joined with the loyalists in making war upon the prince. Richard forgave Marshal his first error of judgement, and allowed him to succeed his brother, John Marshal, in the hereditary marshalship, and on his death-bed designated him as custodian of Rouen and of the royal treasure during the interregnum.

King John and Magna Carta:

William supported King John when he became king in 1199, but they had a falling out when William paid homage to King Philip II of France for his Norman lands of Orbec and Longueville. William left for Leinster in 1207 and stayed in Ireland until 1212, during which time he had Carlow Castle erected[1]. In 1212 he was summoned to fight in the Welsh wars. Despite these differences, it was William on 15 June 1215 at Runnymede who dealt with the barons who made King John agree to the Magna Carta, and he was one of the few English noblemen to remain loyal to the royal side through the First Barons' War. It was William whom King John trusted on his deathbed to make sure John's nine-year-old son Henry would get the throne.

On 11 November 1216, upon the death of King John, William Marshal was named by the king's council (the chief barons who had remained loyal to King John in the First Barons' War) to serve as both regent of the 9 year old King Henry III, and regent of the kingdom. In spite of his advanced age (around 70) he prosecuted the war against Prince Louis and the rebel barons with remarkable energy. In the battle of Lincoln he charged and fought at the head of the young King's army, leading them to victory. He was preparing to besiege Louis in London when the war was terminated by the naval victory of Hubert de Burgh in the straits of Dover. He was criticized for the generosity of the terms he accorded to Louis and the rebels in September 1217; but his desire for an expeditious settlement was dictated by sound statesmanship. Self-restraint and compromise were the key-notes of Marshal's policy, hoping to secure peace and stability for his young liege. Both before and after the peace of 1217 he reissued Magna Carta, in which he is a signatory as one of the witnessing barons. Without his presence England might not have survived the disastrous reign of John; where the French and the rebels would not trust the English king's word, they would trust William.

Death and legacy

William Marshal was interred in Temple Church, London

William Marshal's health finally failed him in February 1219. In March 1219 he realized that he was dying, so he summoned his eldest son, also William, and his household knights, and left the Tower of London for his estate at Caversham in Oxfordshire, near Reading, where he called a meeting of the barons, Henry III, the papal legate, the royal justiciar (Hubert de Burgh), and Peter des Roches (Bishop of Winchester and the young King's guardian). William rejected the Bishop's claim to the regency and entrusted the regency to the care of the papal legate; he apparently did not trust the Bishop or any of the other magnates that he had gathered to this meeting. Fulfilling the vow he had made while on crusade, he was invested into the order of the Knights Templar on his deathbed. He died on 14 May 1219 at Caversham, and was buried in the Temple Church in London, where his effigy can still be seen.

After his death, his eldest son, also named William, commissioned a biography of his father to be written called L'Histoire de Guillaume le Marechal. This book, written so soon after his death, has preserved (and probably enhanced) the legend of William Marshal for posterity. While his knightly achievements may be debatable, there is no doubt of his impact on the history and politics of England, from his stalwart defence of the realm to his support of the Magna Carta.

The Fate of the Marshal Family:

During the civil wars in Ireland, William had taken two manors that the Bishop of Ferns claimed but could not get back. Some years after William's death, that bishop is said to have laid a curse on the family that William's sons would have no children, and the great Marshal estates would be scattered. Each of William's sons did become earl of Pembroke and marshal of England, and each died without issue. William's vast holdings were then divided among the husbands of his five daughters. The title of "Marshal" went to the husband of the oldest daughter, Hugh Bigod, 3rd Earl of Norfolk, and later passed to the Mowbray dukes of Norfolk and then to the Howard dukes of Norfolk, becoming "Earl Marshal" along the way. The title of "Earl of Pembroke" passed to William of Valence, the husband of Joan Marshal's daughter, Joan de Munchensi; he became the first of the de Valence line of earls of Pembroke.

William Marshal in fiction:

William appears (named only as the Earl of Pembroke) in William Shakespeare's historical play King John.

William — Isabel De Clare. Isabel (daughter of Richard De Clare and Aoife of Leinster) was born 1172, Ireland; died 1220; was buried , Monmouthshire, Wales. [Group Sheet]

Other Events:

• Reference Number: 15700

Notes:

Isabel de Clare, suo jure Countess of Pembroke and Striguil (1172-1220), was a Cambro-Norman-Irish noblewoman and one of the greatest heiresses in Wales and Ireland. She was the wife of William Marshall, 1st Earl of Pembroke (1146 - 14 May 1219)

Family:

Isabel was born in 1172 in Ireland, the eldest child of Richard de Clare, 2nd Earl of Pembroke (1130 - 20 April 1176), known to history as Strongbow, and Aoife of Leinster, the daughter of Dermot MacMurrough, King of Leinster and Mor O'Toole. The latter was a daughter of Muitchertach O'Toole and Cacht Inion Loigsig O'Morda. The marriage of Strongbow and Aoife took place in August 1170, the day after the capture of Waterford by the Cambro-Norman forces led by Strongbow, and abetted by Dermot MacMurrough.

Isabel's paternal grandparents were Gilbert de Clare, 1st Earl of Pembroke and Isabella de Meulan. She had a younger brother Gilbert de Striguil, who died at the age of twelve having succeeded their father in 1176 as the 3rd Earl of Pembroke. She also had an illegitimate half-sister Basile de Clare, who married three times. Basile's husbands were: Robert de Quincy; Raymond Fitzgerald, Constable of Leinster: Geoffrey FitzRobert, Baron of Kells.

Isabel was described as pleasant, gentle, and extremely attractive. After her brother Gilbert's death in 1185, she became one of the wealthiest heiresses in the kingdom, owning besides the suo jure titles of Pembroke and Striguil much land in Wales and Ireland. She inherited the numerous castles on the inlet of Milford Haven, guarding the South Channel, including Pembroke Castle.[1] She was a ward of King Henry II.

Marriage:

The new King Richard I arranged her marriage in August 1189 to William Marshall, the greatest knight and soldier in the realm. Henry II had promised Marshall he would be given Isabel as his bride, and his son Richard upheld the promise one month after his ascension to the throne. William Marshall would serve as Lord Marshal of England, four kings in all: Henry II, Richard I, John, and Henry III. After his marriage to Isabel, Marshall became the jure uxoris 1st Earl of Pembroke, Earl of Striguil, and assumed overlordship of Leinster in Ireland, Pembroke Castle, Chepstow Castle, as well as Isabel's other castles in Wales such as the keep of Haverford, Tenby, Lewhaden, Narberth, Stackpole. In 1189, shortly after their marriage, Marshall and Isabella arrived in Ireland, at Old Ros, a settlement located in the territory which belonged to her grandfather, Dermot MacMurrough. A motte was hastily constructed, a medieval borough quickly grew around it, and afterwards the Marshalls founded the port town by the river which subsequently became known as New Ross. The Chronicles of Ros, which are housed in the British Museum, described Isabella and Marshall's arrival in Ireland and records that Isabella set about building a lovely city on the banks of the Barrow.

The marriage was happy, despite the vast difference in age between them. William Marshall and Isabel produced a total of five sons and five daughters.

List of children:

William Marshal, 2nd Earl of Pembroke (1190 - 6 April 1231). Chief Justiciar of Ireland. He married firstly, Alice de Bethune, and secondly, Eleanor Plantagenet, daughter of King John. He died childless.

Maud Marshal (1192 - 27 March 1248). She married firstly, Hugh Bigod, 3rd Earl of Norfolk, by whom she had issue; she married secondly, William de Warenne, 6th Earl of Surrey, by whom she had issue, including John de Warenne, 7th Earl of Surrey who married Alice le Brun de Lusignan; she married thirdly, Walter de Dunstanville.
Gilbert Marshal, 4th Earl of Pembroke (1194 - 27 June 1241). He married firstly, Margaret of Scotland; and secondly, Maud de Lanvaley. He died childless.

Anselm Marshal, 6th Earl of Pembroke (1198 - 22 December 1245). He married Maud de Bohun. He died childless.

Legacy

Isabel died in Pembrokeshire, Wales in 1220 at the age of forty-eight. Her husband had died the year before. She is buried at Tintern Abbey, Monmouthshire.

Although her daughters had many children, her five sons, curiously, died childless. This is supposedly attributed to a curse placed upon William Marshal by the Irish Bishop of Ferns.[3]The title of marshal subsequently passed to Hugh de Bigod, husband of Isabel's eldest daughter Maud, while the title of Earl of Pembroke went to William de Valence, 1st Earl of Pembroke, the husband of Joan de Munchensi, daughter of Joan Marshal. He was the first of the de Valence line of the earls of Pembroke.
