William and Gundrada de Warenne and the Foundation of a Dynasty

William de Warenne, Holy Trinity Church, Southover

William de Warenne, first earl of Surrey, was a younger son of Rodulf de Warenne and his wife Beatrix. It is possible that Beatrix was a niece of Duchess Gunnor of Normandy, making young William a cousin of William the Bastard, Duke of Normandy. The family name is probably derived from the hamlet of Varenne, part of the Warenne lands in the modern French department of Seine-Inférieure, Normandy. William’s older brother, Rodulf or Ralph, would inherit the greater part of the Warenne family estates in Normandy.

William’s date of birth is unrecorded; a younger son of the minor nobility does not tend to get a mention until he does something remarkable or becomes someone notable. Although still young William was considered a capable and experienced enough soldier to be given joint command of a Norman army, by the mid-1050s. His first recorded military action is in the 1054 campaign against the French. He was one of the commanders who fought against the King of France’s brother, Count Odo, at the Battle of Mortemer.  

De Warenne was rewarded with some of the lands of his kinsman, Roger (I) de Mortemer, who had fought for the French. William managed to retain some of these lands even after Mortemer was restored to favour, including the castles of Mortemer and Bellencombre. Bellencrombe would become the capital of the de Warenne estates in Normandy. De Warenne had also received some of  the confiscated lands of William, count of Arques in 1053. Duke William’s confidence in de Warenne is demonstrated in the fact he was one of the barons consulted during the planning of the invasion of England in 1066.

In fact, William de Warenne is one of only a handful of Norman barons who can be positively identified as having fought at the Battle of Hastings on 14th October, 1066. De Warenne was rewarded with vast swathes of land throughout the country. According to the Domesday survey his lands extended over 13 counties: stretching from Conisbrough in Yorkshire to Lewes in Sussex. His territories were acquired over the course of the reign of William I and elevated him the highest rank of magnates. By 1086 his riches were only surpassed by the king’s half-brothers and his own kinsman, Roger de Montgomery. He still ranks in the Top 20 of the richest people in the world – ever!

Throughout his career, William de Warenne acquired lands in numerous counties, sometimes by nefarious means. Much of the property, such as Conisbrough, had formerly belonged to the late king, Harold. In Norfolk he is said to have asserted lordship over freemen not necessarily assigned to him. He had disputes with neighbouring landowners in Conisbrough, over which properties were sokelands and he is said to have stolen lands from the bishop of Durham and the abbot of Ely. Some acquisitions were obtained peacefully, such as the manor of Whitchurch in Shropshire, which was left to him by his kinsman Roger de Montgomery. William was an energetic and attentive landowner and improved the economy of most of his estates; more than tripling his sheep flock at Castle Acre and doubling the value of his Yorkshire estates in just 20 years (at a time when the county was devastated by the Harrying of the North).

In 1067 William de Warenne was one of 4 prominent Normans appointed to govern England during William the Conqueror’s absence in Normandy. Following the Conquest, he continued to support the king and – subsequently – his son, William II Rufus – as a military commander for over 20 years. In 1074 he was with his father at the abbey of Holy Trinity in Rouen, where he was a witness to his father’s last known charter, and in 1083-85 he fought with the king on campaign in Maine, being wounded at the siege of the castle of Sainte-Suzanne.

In 1075, along with Richard de Clare, his fellow justiciar, he was sent to deal with the rebellion of Earl Ralph de Gael of East Anglia. De Gael had failed to respond to their summons to answer for an act of defiance and so the 2 lords faced and defeated the rebels at Fawdon in Cambridgeshire, mutilating their prisoners afterwards. Ralph withdrew to Norwich Castle; besieged for 3 months he managed to escape his attackers by boat, while the castle surrendered and was occupied by de Warenne.

William de Warenne was married to a Flemish noblewoman, Gundrada; her brother Gerbod was sometime earl of Chester and another brother, Frederic, held lands in Norfolk which eventually passed to Gundrada. Frederic, appears to have jointly, with Gundrada, held lands in England even before the Conquest, when two people named Frederic and Gundrada are mentioned as holding four manors in Kent and Sussex. It would indeed be a coincidence if there were two other related people, named Frederic and Gundrada, very distinctive foreign names, in England at that time. Gundrada’s brothers, it seems, were deeply involved in the border politics between Flanders and Normandy; indeed, it is thought that Gerbod resigned his responsibilities in Chester in order to return to the Continent to oversee the family’s lands and duties there, following the death of an older brother, Arnulf II of Oosterzele-Scheldewindeke.

Frederic was murdered by English freedom fighter, Hereward the Wake; his murder giving rise to a personal feud between Hereward and William de Warenne:

‘Among his other crimes, by trickery [Hereward] killed Frederick, brother of Earl William of Warenne, a man distinguished by lineage and possessions, who one night was surrounded in his own house. On account of his murder, such discord arose between Hereward and the aforesaid William that it could not be settled by any reparation nor in any court.’1

There has been considerable debate among historians over the theory that Gundrada may have been the daughter of William the Conqueror, but the confusion appears to have come from an unreliable charter belonging to Lewes Priory and Gundrada being part of the household of King William’s wife, Matilda. The confirmation charter of the foundation of the priory has King William naming ‘William de Warenne and his wife Gundrada, my daughter.’2 In the same charter, William de Warenne pleads ‘for the health of my mistress Queen Matilda, mother of my wife.’3  However, this is a confirmation of an earlier charter and in the original, while the king and William de Warenne, both, mention Gundrada, neither refer to her as being related to the king or queen.

Historian Elisabeth van Houts argues that Gundrada was most likely a distant relative of Queen Matilda and the counts of Flanders, as asserted in her epitaph as ‘offspring of dukes’ and a ‘noble shoot’. Indeed, had her father been William the Conqueror, her epitaph would surely have referred to her as the offspring of kings. Even if she had been the daughter of Matilda by an earlier marriage, off-spring of kings would have still been appropriate, given that Queen Matilda was the granddaughter of King Robert II of France. Though it does seem likely that Matilda and Gundrada were related in some way, perhaps distant cousins.

The ‘dukes’ referred to in Gundrada’s epitaph, although naturally assumed to be of Normandy, could well refer to a kinship with the house of Luxembourg, to which Queen Matilda’s paternal grandmother, Orgive, belonged. Moreover, Frederic was a familial name within the house of Luxembourg. This kinship via the House of Luxembourg with Queen Matilda would also explain the queen’s gift to Gundrada, of the manor of Carlton, which is usually given as evidence that Gundrada belonged to the queen’s household; an association which would be entirely consistent with kinship.

Gundrada and William were married sometime around the time of the Conquest, either before or after the expedition to conquer England. They had 3 children together. Their eldest son, William, would succeed his father as Earl of Surrey and Warenne. He married Isabel de Vermandois, widow of Robert de Beaumont, earl of Leicester; with whom he had, according to one chronicler, been having an affair even before the earl’s death. Young William had a chequered career, he supported the claims of Robert Curthose, Duke of Normandy, to the English throne against the duke’s younger brother, Henry I, but changed sides and fought for Henry at the Battle of Tinchebrai in 1106. Duke Robert lost and was captured and imprisoned by Henry. William remained in the king’s favour for the rest of the reign, fighting alongside Henry at the Battle of Bremule in 1119. William, his son and stepsons were at Henry’s deathbed at Lyons-la-Foret when he died in 1135.

William and Gundrada’s second son, Rainald de Warenne, led the assault on Rouen in 1090, for William II Rufus, in the conflict between the English king and his older brother, Duke Robert. However, by 1105 Rainald was fighting for the duke against the youngest of the Conqueror’s sons, Henry I, defending the castle of Saint-Pierre-sur-Dives for the duke. He was captured by Henry the following year but had been freed by September 1106. It is possible he died shortly after but was certainly dead by 1118 when his brother issued a charter, in which he gave 6 churches to Lewes Priory, for the soul of deceased family members, including Rainald.

Gundrada and William also had a daughter, Edith, who married Gerard de Gournay, son of the lord of Gournay-en-Bray. Gerard also supported William II Rufus against Duke Robert and took part in the Crusade of 1096. Edith later accompanied him on pilgrimage back to Jerusalem, sometime after 1104, where he died. Gerard was succeeded by their son, Hugh de Gournay, whose daughter Gundreda would be the mother of Roger de Mowbray. Edith then married Drew de Monchy, with whom she had a son, Drew the Younger.

Castle Acre, Norfollk, where Gundrada died

Sadly, Gundrada died in childbirth at Castle Acre in Norfolk on 27th May 1085. She was buried in the chapter house of the couple’s own of foundation Lewes Priory.

William’s second wife was a sister of Richard Guet, who was described as ‘frater comitissae Warennae’ when he gave the manor of Cowyck to Bermondsey Abbey in 1098.3 Guet was a landowner in Perche, Normandy, but his sister’s name has not survived the passage of time. All we know of her is that, a few days after her husband’s death, she attempted to gift 100 shillings to Ely Abbey in restitution for damage caused by William de Warenne. The monks refused the donation, hoping that Warenne’s departing soul had been claimed by demons.4

Despite this reputation at Ely, William de Warenne and his wife, Gundrada, had a reputation for piety. At some point in their marriage, probably 1081-3, they went on pilgrimage to Rome. Due of war in Italy they only got as far as the great abbey of Cluny in Burgundy, where they were received into the fellowship of monks. On their return to England, they founded a priory at Lewes, following the Cluniac rule and a prior and 3 monks were sent from Cluny to establish the foundation. It was the first Cluniac foundation in England.

Following the Conqueror’s death, William fought in support of the late king’s second son, William II Rufus against his older brother, Robert Curthose, who had inherited the dukedom of Normandy. He was rewarded in early 1088 with the earldom of Surrey. The new earl fought for William II Rufus during an invasion by Robert’s supporters and was badly wounded at the siege of Pevensey Castle, East Sussex, in the spring of 1088. He was taken to Lewes, where he died of his wounds on 24th June of the same year. Earl Warenne was buried beside his first wife, Gundrada, in the chapter house of Lewes Priory.

Following the dissolution of Lewes Priory in the 16th century, Gundrada’s tombstone was first moved to Isfield Church; it was moved again in 1775 to the parish church of St John the Baptist at Southover in Lewes. The remains of Gundrada and William, themselves, were discovered in 2 leaden chests in 1845, when the railway line was excavated through the priory grounds. They were laid to rest, for a final time, at the Southover church, in 1847, in a chapel dedicated to Gundrada de Warenne.

William and Gundrada de Warenne had founded a dynasty that would survive for almost 300 years, dying out in the reign of Edward III following the disastrous marriage of John de Warenne, 7th and last Earl of Warenne and Surrey
