Robert Fitzhamon (died March 1107), or Robert FitzHamon, Seigneur de Lord of Glamorgan in 1075.

As a kinsman of the Conqueror and one of the few Anglo-Norman barons to remain loyal to the two successive kings William Rufus and Henry I of England, he was a prominent figure in England and Normandy.

Not much is known about his earlier life, or his precise relationship to William I of England.

Parentage and ancestry

Robert FitzHamon (born c. 1045-1055, d. March 1107 Falaise, Normandy) was, as the prefix Fitz (fils de, "son of") suggests, the son of Hamo Dapifer the Sheriff of Kent and grandson of Hamon Dentatus ('The Betoothed or Toothy', i.e., probably buck-toothed). His grandfather held the lordships of Torigny, Creully, Mézy, and Evrecy in Normandy, but following his death at the Battle of Val-ès-Dunes in 1047, the family might have lost these lordships.

Career in England and Wales

Few details of Robert's career prior to 1087 are available. Robert probably did not fight at the Battle of Hastings in 1066, and does not appear in the Domesday Book of 1086, although some of his relatives are listed therein. He first comes to prominence in surviving records as a supporter of King William Rufus (1087-1100) during the Rebellion of 1088. After the revolt was defeated he was granted as a reward by King William Rufus the feudal barony of Gloucester[3] consisting of over two hundred manors in Gloucestershire and other counties. Some of these had belonged to the late Queen Matilda, consort of William the Conqueror and mother of William Rufus, and had been seized by her from the great Saxon thane Brictric son of Algar, apparently as a punishment for his having refused her romantic advances in his youth.[4] They had been destined as the inheritance of Rufus's younger brother Henry (the future King Henry I); nevertheless Fitzhamon remained on good terms with Henry.

Conquest of Glamorgan

The chronology of Fitzhamon's conquest of Glamorgan is uncertain, but it probably took place in the decades after he received the feudal barony of Gloucester.

The Twelve Knights of Glamorgan

One explanation is the legend of the

Whether there is any truth in the legend or not Robert Fitzhamon seems to have seized control of the lowlands of Glamorgan and Gwynllwg sometime from around 1089 to 1094. His key strongholds were Cardiff Castle, which already may have been built, on the site of an old Roman fort, new castles at Newport, and at Kenfig. His descendants would inherit these castles and lands.

Rhys's daughter Nest became the mistress of King Henry I of England and allegedly was mother of Robert, 1st Earl of Gloucester who married Mabel, Fitzhamon's daughter and heiress and thus had legitimacy both among the Welsh and the Norman barons.[5] (Robert of Caen's mother is however unknown to historians and genealogists).

Founder of Tewkesbury Abbey (1092)

He also refounded Tewkesbury Abbey in 1092. The abbey's dimensions are almost the same as Westminster Abbey. The first abbot was Giraldus, Abbot of Cranborne (d. 1110) who died before the abbey was consecrated in October 1121. The abbey was apparently built under the influence of his wife Sybil de Montgomery. [4], said to be a beautiful and religious woman like her sisters.

Fitzhamon and His Kings

Legend has it that Robert had ominous dreams in the days before Rufus' fatal hunting expedition, which postponed but did not prevent the outing. He was one of the first to gather in tears around Rufus' corpse, and he used his cloak to cover the late king's body on its journey to be buried in Winchester. How much of these stories are the invention of later days is unknown.

In any case Fitzhamon proved as loyal to Henry I as he had been to his predecessor, remaining on Henry's side in the several open conflicts with Henry's brother Robert Curthose. He was one of the three barons who negotiated the 1101 truce between Henry I and Robert Curthose.

In 1105 he went to Normandy and was captured while fighting near his ancestral estates near Bayeux. This was one of the reasons Henry crossed the channel with a substantial force later that year. Fitzhamon was freed, and joined Henry's campaign, which proceeded to besiege Falaise. There Fitzhamon was severely injured in the head; although he lived two more years he was never the same mentally. He was buried in the Chapter House at Tewkesbury Abbey, which he had founded and considerably enriched during his lifetime.

Marriage and progeny

Fitzhamon married Sybil de Montgomery around 1087 to 1090, apparently the youngest daughter of Roger of Montgomery, 1st Earl of Shrewsbury by his first wife Mabel Talvas, daughter of William I Talvas. She survived her husband and is said to have entered a convent with two of her daughters. By his wife he is said to have had four daughters including:

  • Mabel FitzHamon, eldest daughter, who inherited his great estates and in about 1107 married Robert de Caen, 1st Earl of Gloucester, a natural son of King Henry I (1100-1135). Fitzhamon's huge land-holdings in several counties formed the feudal barony of Gloucester[6] which was inherited by his son-in-law Robert de Caen, who in 1122 was created 1st Earl of Gloucester.[7] Fitzhamon is sometimes called Earl of Gloucester, but was never so created formally. Robert Fitzhamon's great-granddaughter Isabel of Gloucester married King John (1199-1216).
  • Isabella (or Hawisa) FitzHamon, said to have married a count from Brittany, but no further details exist.

Each knight is in armour, and bears in his hand a model of a church. Both are supporting a shield (affixed to a pomegranate tree) bearing the arms of the Abbey, which the blazoning on their own coats repeats.(Massé, H. J. L.
