The Will of Isabel of Castile, Duchess of York, Countess of Cambridge (1355-92)

Isabel of Castile was born sometime in the year 1355 in Tordesillas in central Spain, probably in the royal monastery of Santa Clara, where her father and her grandfather Alfonso XI (b. 1311, r. 1312-50) had built a palace. Isabel was the third daughter of Pedro 'the Cruel', king of Castile and Leon (b. 1334, r. 1350-69) and his long-term mistress Doña María de Padilla, a Castilian noblewoman; her older sisters were Beatriz, born in Córdoba in southern Spain in 1353, who died sometime after 23 September 1366*, and Constanza, born in Castrojeriz in northern Spain in June or July 1354, later duchess of Lancaster. The sisters had a younger full brother, Alfonso, but he died at the age of three in 1362 in the city of Seville, and they had at least five other illegitimate half-siblings, born to Pedro's other lovers. The Cortes of Castile declared the three sisters legitimate after King Pedro pretended that he had married María de Padilla in 1352, the year before he wed his unfortunate French wife Blanche de Bourbon, whom he imprisoned shortly after their wedding and who died still in prison in 1361. Constanza, as the elder of the two surviving royal Castilian daughters, inherited her father's kingdoms, at least nominally, after Pedro was killed by his illegitimate half-brother and deadly enemy Enrique of Trastámara in March 1369. In reality, Trastámara became King Enrique II of Castile and Leon, and was succeeded by his son Juan I in 1379 and then his grandson Enrique III in 1390. 

* When King Pedro talked of "our three daughters" (tres filiae nostrae): Foedera 1361-77, pp. 805-6.

Constanza and Isabel of Castile moved to England in the early 1370s and married the royal brothers John of Gaunt, duke of Lancaster and earl of Leicester, Lincoln, Derby and Richmond, and Edmund of Langley, earl of Cambridge, sons of Edward III and Philippa of Hainault. If their elder sister Beatriz had still been alive at this point, she would have been their father's rightful heir, and John of Gaunt, who named himself king of Castile and Leon from 1372 onwards, would have married her, rather than Constanza. Edmund of Langley, born c. 5 June 1341, was fourteen years older than his new wife, and was thirty-one to her seventeen, or sixteen going on seventeen, when they married in July 1372. Isabel became a duchess in 1385 when Richard II granted his uncle Edmund the dukedom of York, and had three children: Edward, duke of York, killed at the battle of Agincourt in 1415; Constance, Lady Despenser and briefly countess of Gloucester (d. 1416); and Richard, earl of Cambridge (executed 1415), grandfather of Edward IV and Richard III. Duchess Isabel died at the age of only thirty-seven on 23 December 1392, leaving a will which she made in French a few weeks before her death, now held in the National Archives.

A translation of Isabel of Castile's will was printed in 1826 in the first volume of Testamenta Vetusta, but unfortunately it is much shortened and has led numerous writers, including myself, astray regarding the nature of Isabel's relationship with her husband. Isabel's entry in the Oxford Dictionary of National Biography states, entirely wrongly but understandably, that she made no legacies to her husband and that her will consists of "a few bequests of jewellery". Nope, really, really not. Having seen and read the entire will, it is astonishing to me just how abbreviated the Vetusta translation is; it's maybe 5% of the original text. The sub-title of Testamenta Vetusta does say Being Illustrations from Wills, and it doesn't claim to translate all the text of the fourteenth- and fifteenth-century wills it includes, but still, the translations are highly misleading because it isn't made clear that the editor translated every fifth or tenth or twentieth line of each will and left out the rest. Its 'illustration' of the 1380 will of Edmund Mortimer (1352-81), third earl of March, for example, takes up just two and a half pages of Vetusta, but the full will, printed in the original French in A Collection of All the Wills Now Known to be Extant of the Kings and Queens of England, Princes and Princesses of Wales, and Every Branch of the Blood Royal, runs to thirteen pages. John of Gaunt's will is twenty-eight pages in A Collection, but only five pages in Testamenta Vetusta; Edmund of Langley's will is less than a page in Vetusta and two and a half pages in A Collection. So I advise considerable caution if you're using Testamenta Vetusta as a source. 

That being the case, here's some more information about Isabel of Castile's will of 1392 and what she actually bequeathed, not the absurdly abbreviated and hopelessly confusing version of it in Vetusta. The duchess left items to the following people, named here in the order in which they appear in the will (in order of rank, according to the strict hierarchical etiquette of the era): her nephew-in-law Richard II, king of England; Richard's queen, Anne of Bohemia; Isabel's brother-in-law John of Gaunt, duke of Lancaster; her husband Edmund of Langley, duke of York; all three of Isabel and Edmund's children, Edward, Constance and Richard; Eleanor de Bohun, duchess of Gloucester and the wife of Thomas of Woodstock, Edmund of Langley and John of Gaunt's youngest brother; and, rather intriguingly, John Holland, earl of Huntingdon. Isabel also left numerous items and gifts of cash to a long list of her servants and attendants, none of which are mentioned at all in the Vetusta abstract of her will, so you'd have no idea of her generosity and kindness to them unless you make the effort to locate and look at the original text of her will.

John Holland, earl of Huntingdon, was the only noble/royal person in the will who wasn't a close relative of the duchess of York by blood or marriage, though he was Richard II's half-brother and was married to John of Gaunt's daughter Elizabeth of Lancaster. It's also, to my mind, rather fascinating that Isabel left nothing at all to her older sister Constanza of Castile, duchess of Lancaster, and failed even to mention her, and although she left items to Eleanor, duchess of Gloucester, she gave nothing to Eleanor's husband Thomas of Woodstock, her (Isabel's) own brother-in-law.

To John Holland (al counte de Huntyngdon), Isabel left her two Bibles, and "the best fillet that I have". The meaning of 'fillet' in this context is unclear to me; it usually meant a decorative headband of interlaced wire or a string of jewels to be worn on the head, but this was not an item one would expect to see being bequeathed to a man. There's definitely no squiggle above the word counte, 'earl', however, to indicate that the word is abbreviated and that Isabel actually intended to refer to the countess, Elizabeth of Lancaster, and the al, 'to the [earl]', is in the masculine form anyway. As well as these items, Isabel left to her elder son Edward some valuable gifts which John Holland had given to her: a gold cup, a gold brooch with "very large pearls and three sapphires" and a gold chaplet with white flowers, all of which "the earl of Huntingdon gave me" (q' le counte de Huntyndon me donna). The gold cup Holland had given her was engraved with Isabel's arms - presumably she meant the arms of Castile - so evidently he had had it especially made for her. Given the theory that Isabel of Castile and John Holland had an affair, this does perhaps add some fuel to that particular fire. Although the English nobility did send each other gifts on a regular basis, the presents John Holland gave to her were the only ones Isabel mentioned in her will.

To Anne of Bohemia, "my very dread lady the queen" (ma tresredoutee dame la Royne), Isabel gave seven gold belts; to Anne's husband Richard II, she gave a drinking-horn studded with pearls; and to the man who was both her husband's brother and her sister's husband, John of Gaunt, whom she called "my very honoured brother of Lancaster", Isabel gave a tablet of jasper which "the king of Armonie gave me". That's a reference to Levon or Leo, king of Cilician Armenia, who had visited England some years before. Duchess Isabel also left several tablets of gold and a "psalter with the arms of Northampton" to "my very honoured sister of Gloucester", i.e. Eleanor de Bohun. The duchess's father Humphrey de Bohun (1342-73) had been earl of Northampton, which suggests that the psalter had been a gift to Isabel from a member of the de Bohun family in the first place (I might speculate that it was a wedding gift to Isabel from Humphrey in July 1372, a few months before he died, but obviously I can't know for sure).

Isabel referred to Edmund of Langley as her "very honoured lord and husband of York", and left him all her horses, all her beds (tous mez litz) including the cushions, bedspreads, canopies and everything else that went with them, her best brooch, her best gold cup, and her "large primer". It is emphatically not the case that she did not bequeath him anything, and why the translator/editor of Testamenta Vetusta left all of this out is beyond me (he also left out her bequests to John Holland). To her elder son Edward, earl of Rutland (counte de Ruttellond), Isabel left the items mentioned above which she had been given by John Holland, and her crown, leaving him strict instructions never to sell it or give it away but to keep it in the family. To "my beloved daughter [ma t'samee fille] Constance la Despenser", Isabel gave a fret, i.e. a head-covering of interlaced wire, with pearls, her best fillet, and her silver scelle, which could mean saddle or stool. She then asked her nephew-in-law the king to "take his humble godson [humble filiol] to heart", meaning her youngest child Richard of Conisbrough, who was a good bit younger than his two siblings and wasn't specifically left any bequests except his mother's "beautiful psalter".

Isabel also left items and gifts of money to numerous servants of hers, both men and women; just to pick out a couple of examples more or less at random, she gave thirty shillings to 'John of the Wardrobe', ten marks to Roger Palfrayman, and good brooches to Elianor Southfeld and Marie Weston. Another female attendant of Isabel's named in the will, to whom she left a gown and a cloak, is a woman stated by the chronicler Jean Froissart to have been the mistress of the duchess's brother-in-law John of Gaunt; more info is available in my biography of him, due out early next year.

Edward II's Attacks on Normandy and the French Fleet in August/September 1326

A post about a curious and little-known event which took place late in Edward II's reign: the king's attacks on the French duchy of Normandy and on Norman ships in the late summer of 1326. The whole affair is obscure and barely came to the attention of contemporary chroniclers, though there are some references to it in the chancery rolls and, in particular, in Edward II's chamber account of 1325/26. Natalie Fryde and Roy Martin Haines, two of the very few historians to discuss the incident, date the attack to the first half of September 1326, though it's clear from the royal chamber account that at least part of the engagement actually took place in August. [1] It's all very difficult to figure out, firstly because, as noted, the event is weirdly obscure; secondly because Edward II's summons for armed men to attack the French and/or Normandy are easily confused with his summons to repel Queen Isabella's invasion force, which landed in Suffolk on 24 September 1326; and thirdly because the sources we do have seem to contradict each other, or rather, seem to be describing several different events. Therefore, this post is probably somewhat incoherent, for which, my apologies.

The background, very briefly, is that Edward II again went to war against his brother-in-law Charles IV of France in the summer of 1326, and his wife Isabella and their teenage son Edward of Windsor had been in France since 1325 and were refusing to return to England (or at least, Isabella was, and was keeping her son with her in her homeland). The earliest reference I can find to something happening in Normandy dates to 6 August 1326, when Edward II was leaving Portchester on the Hampshire coast and was on his way to his palace of Clarendon just outside Salisbury in Wiltshire. His chamber account shows that he gave £10 on that date to two men: Jack Pyk of Winchelsea in Sussex, a valet of the royal chamber and the captain of a royal ship called the Blome, and Pey-Bernat de Pynsole from Bayonne, a Gascon sergeant-at-arms in the king's household and the captain of another royal ship called the Petre. This entry states that Jack and Pey-Bernat had sailed to Portchester "in two long boats" to inform Edward and Hugh Despenser the Younger of recent events, and arrived just before Edward's departure for Clarendon. They told the king and his chamberlain that an English fleet had conquis, i.e. 'defeated' or 'captured' or 'taken by force', 140 ships from Edward's "enemies of Normandy" (enemys de Normandie). Something pretty major had already happened at sea by early August 1326, and the English side evidently had the best of it, though frustratingly I can't find any other reference to this. You'd think, surely, that an English fleet capturing well over 100 French ships might have appeared in a chronicle somewhere.

Below, p. 80 of Edward II's chamber account of 1325/26, Manuscript 122 in the library of the Society of Antiquaries in London, talking about Jack Pyk and Pey-Bernat de Pynsole's visit to Edward and Hugh Despenser in Portchester in early August 1326.


The king spent much of August 1326 at his palace of Clarendon. While there on 18 August, Edward ordered his treasurer and the barons of the Exchequer to have the following provisions sent to Portchester Castle by "Saturday the morrow of the Decollation of St John the Baptist", i.e. 30 August: "100 cross-bows with windlass for two feet, 200 cross-bows for one foot, with baldrics and quarrells sufficient for them, 100 hand-bows, with 1,000 cords for the same, and 1,000 heads for arrows, and 20 lbs. of glue, 100 lbs. of thread fit for the strings of cross-bows, and a sufficient quantity of cat-gut". On the same day, the king sent letters to the mayor and bailiffs of numerous ports along the coast of the south of England, and ordered them to have all the ships in their jurisdiction able to carry "50 tuns and upwards" sent to Portsmouth also by 30 August, "to set out in the king's service against the attack of the French". 

Edward also sent letters on 12 August to the archbishops of Canterbury and York, Walter Reynolds (d. 1327) and William Melton (d. 1340). He declared that his aim was to "restrain the malice of the men of the king of France", who were allegedly detaining Edward's wife and son in France against their will - a convenient fiction - and who, rather more plausibly, were, he said, capturing English ships and slaying the sailors and merchants on board. Ten days later, still at Clarendon, Edward ordered the sheriff of Kent to send fifty-four "well-armed footmen" to Portsmouth. Thirty men would be under the command of Richard Haukyn, captain of a ship called the Mariot, and twenty-four under the command of Robert Frende, captain of the Alice. The sheriff of Hampshire was to send 200 armed footmen to Portsmouth in thirteen ships, and according to the annalist of St Paul's in London, one of the very few chroniclers who mentioned the Normandy incident (albeit extremely briefly), another 100 men went from London and 100 from Kent. [3] The admiral of the western fleet, Sir Nicholas Kyriel of Kent (b. December 1282) - whose surname is spelt in approximately 117 different ways in contemporary documents, including Cryel and Crioll - and Peter Barde, bailiff of the Kent port of Sandwich and captain of the king's ship the Cog John (and a future admiral), visited Edward on 27 August 1326. They were given 100 marks (£66.66) because they had purchased ships for an assault on Normandy. [4] On 26 and 29 August and again on 10 September, Edward II ordered the arrest of all French people living in England. [5]

Natalie Fryde (Tyranny and Fall of Edward II, p. 184) cites the Canterbury chronicler's statement that Edward II sent a fleet of 300 ships to attack Normandy. As is usually the case when medieval chroniclers give numbers, this seems likely to be an exaggeration. According to Edward III, after he had succeeded his father as king some months later, the assault on Normandy took place "while we [i.e. himself] were in those parts" (dum eramus in partibus illis). His statement occurred in the context of a royal pardon for Sir John Felton, a knight who had been in the retinue of the late Hugh Despenser the Younger and was staunchly loyal to him, for holding Caerphilly Castle against Queen Isabella and for "invading Normandy and committing depredations" while the young king was there. [6] I don't know whether Edward III meant that he was specifically in Normandy in August/September 1326 or whether "in those parts" meant France more generally, though Natalie Fryde speculates that Edward II intended to seize his son in Normandy and return him to England. It certainly seems possible that the king had received intelligence that his son was in Normandy, though in fact the thirteen-year-old duke of Aquitaine and his mother Isabella had arrived in the county of Hainault by 27 August 1326, on which date the young duke was betrothed to Philippa of Hainault. As for Sir John Felton, he doesn't appear in Edward II's chamber account in connection with the raid on Normandy, as far as I can tell, though on 5 August 1326, the king gave him £5 for his excellent service to Hugh Despenser the Younger. [7]

Several entries in the chamber account indicate that some kind of engagement between English and French ships took place off the coast of Brittany, which was ruled at the time by Edward II's kinsman Duke John III (1286-1341), grandson of Edward I's sister Beatrice (1242-75) and a man with whom Edward II appears to have been on perfectly amicable terms and with whom he was in occasional contact in 1326. The duchy of Brittany was, unlike the duchy of Normandy, independent from the kingdom of France. On 3, 6 and 9 September 1326, entries in the chamber account mention "two ships of Normandy" (ij niefs de Normandie) called La Dorre and Cog Seint Thomas which had been captured off the coast of Brittany and taken to the port of Winchelsea by John Pym and other sailors in August. Assuming that the 140 ships captured by the English fleet, as also stated in the chamber account, is an even remotely correct number and not a wild exaggeration, I have no idea what happened to the other 138 of them. The king sent a sailor called Litel John (i.e. Little John) to Winchelsea with letters for Stephen and Robert Alard - the Alards were a thirteenth/fourteenth-century naval family of Winchelsea whose tombs can still be seen in the church of St Thomas the Martyr in the town - ordering them to take La Dorre to Portsmouth. Stephen Alard received a gift of £5 from the king on 15 September 1326 because he "went to sea with the great fleet" (ala a la meer oue la g'de flote). Stephen was said to be staying in Portchester Castle around this time, ill, though whether that means he was injured at sea or in Normandy while fighting against the French, or maybe just had a head cold or something, isn't clarified.

Rauf Rosekyn, captain of a royal ship called the James, seized the sum of £15 from a French ship "at Oderne in the parts of Brittany", which I assume means Audierne, and gave it to Edward II on or before 20 September 1326. The port of Audierne lies in the south of Brittany, pretty far from Normandy, so how Rosekyn's action fits in with an assault on Normandy and with Edward II's possible intention to seize his thirteen-year-old son there, I have no idea. On 28 June 1326, Rauf Rosekyn, as captain of the James, had been one of a number of ships' captains "whom the king is sending to diverse parts to further business enjoined on him", as stated on the Patent Roll. The others were Jack Pyk of the Blome, Per-Bernat de Pynsole, now in command of the Seint Edward, and Peter Barde of the Cog John, all named above; Rauf's brother Andrew Rosekyn of the Marie; Richard 'Hick' Fille of the Despenser; John Dyn of the Nicholas; Bernard Prioret of the Alianore; Badin Fourne of a galley also called Seint Edward; and Robert Bataill of the Godyere ('Goodyear'). The combined crew of these men's ships totalled 780 men. A few weeks later on 23 July 1326, another four ships' captains - Richard Councedieu of the Valence, William Pouche of the Blithe, Roger Catour of the Cog Nostre Dame and Robert Metacre of the Maudeleyne - were sent "to diverse parts on the king's affairs" with a total crew of 220 men. As is frustratingly often the case in the chancery rolls, what the men were up to was not specified, but given that Rauf Rosekyn appears in Edward II's chamber account a couple of months later and had clearly been involved in some kind of skirmish with a French ship off the coast of Brittany, it seems reasonable to assume that the other captains were sent on the same mission.

On 7 September 1326, there's a reference in the chamber account to three sailors from Bayonne in Gascony, part of Edward II's domains, whose names were recorded as Will Bernard and Garsy and Ernaud Remond (I doubt the first man was actually called 'Will', but Edward's chamber clerks usually anglicised French names even though they were writing in French). The three sailors had paid £20 for a ship in which they sailed against "the king's enemies of Normandy in the month of August", and the captain of the ship was Thomas Springet of Greenwich, a sailor who often appears in Edward II's accounts and was close enough to him that he was allowed to talk to the king in person in Edward's private rooms. [8] A couple of years earlier in 1323/24, some of the townspeople of Bayonne were involved in a feud with sailors from Normandy, and were summoned to appear before the seneschal of Poitou to explain the damages they had inflicted on Norman ships at sea. Sir Ralph Basset, steward of Gascony, sent a letter to Edward II about the ryote (dispute or quarrel) between "your people of Bayonne and the people of Normandy" in January 1324. [9] An earlier dispute between Gascon and Norman mariners, back in 1293, blew up into a war between England and France.

The reasons for Edward II's attacks on Normandy and on French ships are not entirely clear, and the silence of most chroniclers does not help (perhaps the ever-useful Vita Edwardi Secundi would have given an account of the event, but unfortunately the text ends abruptly in late 1325). It may be that Edward's son was in Normandy or at least that he believed him to be, or perhaps the king intended a pre-emptive strike against the French, in the belief that Charles IV would aid his sister Isabella during her invasion of England. Walter Reynolds, archbishop of Canterbury, told Edward in January 1326 that he had heard news of a hostile fleet gathering in Normandy. [10] That may be true, or it may simply have been one of the many rumours flying around at the end of Edward II's reign.

The sizeable numbers of men and ships gathered in Portsmouth at the end of August 1326, plus the 1,000 men in fifteen ships sent somewhere on the king's business in June and July and their activities off the coast of Brittany, plus the reference to the 140 French ships captured in or before early August, all suggest that Edward II was expecting a full-scale invasion by the French, or hoping to prevent one. The references in his chamber account, however, all talk about les enemys le Roi de Normandie, "the king's enemies of Normandy" specifically, not his "enemies of France", so maybe the whole thing had more to do with the quarrel between Gascon and Norman sailors in some way. Edward's itinerary shows that he arrived in Portchester, close to Portsmouth, on 30 August and remained in the port until 16 or 17 September. While there, his chamber account is full of entries about ships being repaired and refurbished, payments being made to fletchers for feathering arrows, Edward ordering a coat of mail to be made for himself and having his sword and its scabbard mended, etc. There's a general air of military preparation about the whole thing. Whether this was connected to an attack on Normandy or the expected arrival of the queen's invasion force isn't entirely clear, though the reference on 13 September to la guerre entre le Roi e les g'ntz de la t're, "the war between the king and the magnates of the land", suggests the latter. Edward II being Edward II, though, he still found time to pop into a forge and have a chat with local blacksmiths called Philip Darrington and William Dertemewe (i.e. Dartmouth), and several carpenters and fletchers were said to have done their work "in the king's presence".

What actually happened on the ground in Normandy is difficult to ascertain. Roy Martin Haines (King Edward II, p. 172) states that Edward gave the order for his fleet assembled at Portsmouth to "sail to Normandy and there inflict as much damage as possible...The force was repulsed immediately on landing and many men perished. Two days later at the Downs the flotilla was instructed by the king to hasten to Yarmouth, but during the night fifteen of the ships were lost with their men. It was a great disaster". The source appears to be the Canterbury chronicle, also cited by Natalie Fryde, as noted above, and in an endnote on pp. 443-4, Haines explains that the expedition probably landed at Barfleur and raided nearby Cherbourg Abbey. Haines also cites Charles de la Roncière's Histoire de la Marine Française, vol. 1, p. 384, if anyone's interested in digging any deeper.

In any event, according to Haines, the English "great fleet" was repulsed and many men and ships were lost. As he points out, the loss of many English ships was perhaps a reason for the utter failure of Edward II's fleet to prevent the landing of the queen's invasion force on 24 September 1326, though certainly the gross unpopularity of Hugh Despenser the Younger and of the king himself was also a major factor. As the French Chronicle of London says, "the mariners of England were not minded to prevent their coming, by reason of the great anger they entertained against Hugh Despenser [the Younger]." [11] Then again, what happened to all those French/Norman ships supposedly captured by the English sometime before 6 August 1326? Ultimately, I can find very little about this mysterious attack on Normandy, though Seymour Phillips is perhaps correct when he suggests it was a "commando-style raid" intended either to bring Edward II's teenage son back home or to forestall a French attack on England. [12] It is apparent from Edward III's pardon to Sir John Felton in February 1327 that some Englishmen went ashore in Normandy and "committed depredations" there, though how the naval engagement(s?) between English and Norman ships off the coast of Brittany fits into the whole scenario, I don't know.

He married Elizabeth de Burgh on 15 August 1342 when he was still only three years old and she, born on 6 July 1332, was ten, and became a father on 16 August 1355 when he was sixteen. Lionel married his second wife Violante Visconti of Milan a few months before his death on 17 October 1368, aged twenty-nine.

John of Gaunt, titular king of Castile and Leon, second duke of Lancaster, earl of Richmond, Lincoln, Leicester and Derby, b. 6 March 1340 in Ghent in modern-day Belgium, and the third eldest royal son to live into adulthood. John married Blanche of Lancaster in May 1359, Pedro the Cruel's daughter and heir Constanza of Castile in September 1371, and his long-term lover Katherine Swynford in February 1396. John was the father of King Henry IV and grandfather of Henry V, and died on 3 February 1399 a month before his fifty-ninth birthday. Four sons and four daughters outlived him, including the queens of Portugal and Castile.

Edmund of Langley, first duke of York, earl of Cambridge, b. c. 5 June 1341, d. 1 August 1402; the fourth son in a row borne by Queen Philippa. Edmund was the last survivor of Edward III's children, and was the only one to live past 1400. He married Isabel of Castile, younger daughter of Pedro the Cruel, in July 1372, and the decades-younger Joan Holland, daughter of the earl of Kent, in c. November 1393. Edmund had two sons and a daughter from his first marriage.

Blanche of the Tower, b. either March or June 1342, d. in infancy in 1342. If she was born in March 1342, Queen Philippa's pregnancy, given that Edmund was born in June 1341, cannot have gone to term. Blanche was buried in Westminster Abbey in early 1343. Her eldest brother Edward of Woodstock referred to her, in a letter about her burial, as dame Blaunche nostre tres amee soer, 'Lady Blanche, our much loved sister'.

Mary of Waltham, b. 10 October 1344, d. after 1 October 1361; married John of Brittany (b. 1339), later Duke John IV of Brittany, but left no children.

Margaret of Windsor, b. 20 July 1346, d. after 1 October 1361; married John Hastings (b. 29 August 1347), heir to the earldom of Pembroke, but left no children.

William of Windsor, b. c. mid or late May 1348, d. before 5 September 1348; godson of his eldest brother Edward of Woodstock. 

Thomas of Woodstock, first duke of Gloucester, earl of Buckingham and Essex, b. 7 January 1355, d. c. 8 September 1397; the seventh son and the twelfth and youngest child of Edward and Philippa, many years younger than his siblings (after his sisters Mary and Margaret died when he was six or seven, the sibling closest to him in age was Edmund of Langley, thirteen and a half years his senior). Thomas married Eleanor de Bohun (b. 1366) in c. 1374 and had a son and three daughters; his son Humphrey died at the age of seventeen in 1399, and Thomas's sole heir was ultimately his eldest daughter Anne, countess of Stafford (1383-1438). Thomas was murdered in Calais on the orders of his nephew Richard II, most probably on or around 8 September 1397.

Incidentally, 'Thomas of Windsor', another son sometimes assigned to King Edward and Queen Philippa by modern writers, who was supposedly born in the summer of 1347 and died in the same year as his slightly younger brother William of Windsor, did not exist. The 1399 will of Thomas of Woodstock's widow Eleanor de Bohun specifically names her late husband as Edward III's seventh son, and if 'Thomas of Windsor' had ever existed, Woodstock would actually have been the eighth. The invented 'Thomas' has been given the birthplace of William of Windsor, the name of Thomas of Woodstock, and the burial place of Edmund of Langley (Langley Priory in Hertfordshire), and is thus a fictional composite of King Edward and Queen Philippa's three youngest sons.
