    From Wikipedia:

    Roger Mortimer, 3rd Baron Mortimer, 1st Earl of March (25 April 1287 - 29 November 1330), was an English nobleman and powerful Marcher lord who gained many estates in the Welsh Marches and Ireland following his advantageous marriage to the wealthy heiress Joan de Geneville, 2nd Baroness Geneville. In November 1316, he was appointed Lord Lieutenant of Ireland. He was imprisoned in the Tower of London in 1322 for having led the Marcher lords in a revolt against King Edward II in what became known as the Despenser War. He later escaped to France, where he was joined by Edward's queen consort Isabella, whom he took as his mistress. After he and Isabella led a successful invasion and rebellion, Edward was subsequently deposed; Mortimer allegedly arranged his murder at Berkeley Castle. For three years, Mortimer was de facto ruler of England before being himself overthrown by Edward's eldest son, Edward III. Accused of assuming royal power and other crimes, Mortimer was executed by hanging at Tyburn.

    Captain General of the Marshes; Constable of Clun and Hereford Castles; Sheriff of Herefordshire 1266-7.

    According to one chronicle account, it was he who struck the blow that killed Simon de Montfort at Evesham.

    "He had livery of his inheritance 26 February 1246/7; and at Whitsuntide 1253 was made a knight by the King at Winchester. He was serving in Gascony in 1253, and 1254, and from 1255 to 1264 was chiefly occupied with his duties on the March, opposing the successes of his cousin Llewelyn ap Griffith, who was gradually uniting all the Welsh chieftains under his leadership. In the disputes between the King and the Barons in 1258, Mortimer at first took the Barons' side, and was one of the twelve chosen by them to act with twelve chosen by the King, and one of the twenty-four appointed to treat about an aid for the King. In October 1258 he attested the King's proclamation for the observance of the Provisions of Oxford, and in Apr. 1259 was sworn of the King's Council. The 'Provisions' drawn up by the Barons in that year directed that Roger de Mortimer and Philip Basset should accompany the justiciar. On 11 June of that year he was appointed one of the commissioners to demand satisfaction from Llewelyn for breaches of the truce, which on 25 June was prolonged for one year. He was present at the confirmation of the treaty with France, 21 July 1259. On 19 May 1260 the Council of Magnates appointed him constable of Hereford Castle. On 17 July following he arrived in London to attend a Council, and on that day Llewelyn's men took Builth Castle, of which Mortimer had custody for Prince Edward. In December 1260 he had a licence to take game and to fish along the Thames and its tributaries. In December 1261 he was commanded to send his seal, if he were unable to come in person, to have it affixed to the writing made of peace between the King and the Barons. The whole of the years 1262 and 1263 he spent in fighting Llewelyn with varying success. On 3 December 1263 he was one of the armed nobles with the King when Henry demanded, and was refused, entry to Dover Castle; and in January following attested, on the King's side, the submission of the quarrel between Henry and the Barons to Louis, King of France. On 6 April 1264 he was with the King at the taking of Northampton, and captured a number of prisoners; and in May was with the King at Lewes, but fled from the field to Pevensey. He and others who had fled were allowed to return home, giving hostages that they would come to Parliament, when summoned, and stand trial by their peers. Mortimer and the other Lords Marchers did not attend Montfort's 'Parliament' at Midsummer 1264, but were constrained to make peace with him in August. In September Mortimer, as constable of Cardigan, was ordered to give up the castle to Guy de Brien, Montfort's nominee. The Marchers again broke the truce, but before Christmas Montfort and Llewelyn finally reduced them to submission. Soon afterwards Roger and the others were banished to Ireland for a year, but did not go; and in December he had safe conduct to see the King and Prince Edward, who was at Kenilworth. In June 1265 he was among the 'rebels holding certain towns and castles throughout the land, and raising new wars.' Later in the same month he contrived the plan, and furnished the swift horse, by means of which Prince Edward escaped from Hereford Castle and came to Wigmore, where he and Roger de Clifford rode out to meet him and drove off his pursuers. At Evesham, on 4 August 1265, Mortimer commanded the rearguard; and after Montfort's death his head was sent to Mortimer's wife at Wigmore. Mortimer was liberally rewarded, receiving, among other grants, the 'county and honour' of Oxford with lands forfeited by Robert de Vere. In September 1265 he was at the Parliament at Winchester. From Easter 1266 to Michaelmas 1267 he was sheriff of Hereford. On 4 May 1266 he, with Edmund the King's son, and others, was given power to repress the King's enemies; but on 15 May he was heavily defeated by the Welsh at Brecknock, escaping only with difficulty. He took part in the siege of Kenilworth in June 1266. In February 1266/7 he quarrelled with Gloucester over the treatment of the 'disinherited,' whom Gloucester favoured. He was present at the Council at Westminster, 12 February 1269/70. Shortly before Prince Edward sailed for the Holy Land, in August 1270, he was made one of the trustees for the Prince's estates during his absence on the Crusade. On 12 September 1271 he was summoned to 'Parliament' at Westminster. In December 1272 he put down a threatened rising in the North, and the following February was sent to Chester to inquire into complaints against Reynold de Grey, justice there. In 1274 and 1275 he sat as a justice. He was one of the magnates having large interests in Ireland present in Parliament at Westminster, 19 May 1275, who granted the same export duties on wool and hides in their ports in Ireland as had been granted by the lords in England. In October following he was chief assessor of a subsidy in Salop and Staffs. On 12 November 1276 he was one of the magnates at Westminster who gave judgment against Llewelyn; four days later was appointed 'captain' of Salop and cos. Stafford and Hereford and the Marches against the Welsh prince. In 1279 he held a splendid tournament at Kenilworth. On 27 October 1282 the King ordered, 'as a special favour which has never been granted before,' that if Roger should die during his present illness, the executors of his will should not be impeded by reason of his debts to the Exchequer."

    Constable of Clun Castle, Shropshire.

    "In 1216 he had been one of a deputation sent by King John to William de Briwere, after his forced adhesion to the Barons during their occupation of London, to arrange for his return to the King's service; and in September 1217 he had witnessed at Lambeth the articles drawn up between Henry III and Louis of France. On 23 November 1227 he gave £100 as relief for the lands of his brother Hugh, and the King took his homage; and on 8 July 1229, for his faithful service, he was pardoned all except £500 of the debts of his father and brother. In October 1230 he obtained a charter for a fair at Knighton and free warren at Stratfield, and in 1231 he was made custodian of Clun Castle and honour during pleasure. In June 1233, with the other Lords Marchers, Ralph exchanged hostages with the King de fideli servicio, quousque regnum sit ita securatum quod firma pax sit in regno Anglie. On 7 November following he attested a charter of Henry III at Hereford. He was present on 28 January 1235/6 at the confirmation of Magna Carta at Westminster, and in the same year he and the other Lords Marchers claimed the right to find and bear the silvered spears which supported the canopies held over the King and Queen in their Coronation procession; but the right of the Barons of the Cinque Ports to carry both canopies being allowed, the Marchers' claim was rejected as frivolous. In 1241 he was first of the pledges to the King for his sister-in-law Senana, wife of Griffith ap Llewelyn; but in August that year Meredith ap Howel and the other Welsh lords of Kerry made a permanent peace with Henry III, whether they should be at war with Ralph de Mortimer or not. In June 1242 he was summoned to come to the King's aid in Gascony as soon as possible." [Complete Peerage]

    "Ralph [...] was continually engaged on the Welsh marches. At first he stood on the defensive, unable to make much impression on Llywelyn's power. No doubt it was for this reason that in 1230 he married Gwladus Ddu (d. 1251), daughter of Llywelyn and widow of Reginald de Briouze. It was only after the death of his father-in-law in 1240 that Mortimer was able to take the military initiative again, with attacks upon the Welsh. In the summer of 1241 there was war in Maelienydd, and this time the Mortimers prevailed, ending Welsh control of the lordship of Gwrtheyrnion. Ralph (II) died on 6 August 1246 and was buried at Wigmore Abbey, where he was remembered as a warlike and energetic man' (Dugdale, Monasticon, 6, pt 1, 350)." [Oxford Dictionary of National Biography]

    Ralph married Gwladus Ddu Bef 26 Oct 1230. Gwladus (daughter of Llewelyn Fawr ap Iorwerth and Joan of England) died 1251, Windsor, Berkshire, England. [Group Sheet]

  2. 9.  Gwladus Ddu (daughter of Llewelyn Fawr ap Iorwerth and Joan of England); died 1251, Windsor, Berkshire, England.


    Also called Gwladus ferch Llewelyn; Gladusia.

    Notes on the parentage of Gwladus and Margaret, daughters of Llwelyn ap Fawr:

    Complete Peerage (IX:276) and Royal Ancestry both give Gwladus as a daughter of Joan of England. Royal Ancestry gives Margaret as an illegitimate daughter of Llywelyn.

    The Oxford Dictionary of National Biography says that Joan was "probably" the mother of Gwladus and Margaret.

    In The American Genealogist 41:99 (1965), Walter Lee Sheppard notes that "DNB's account gives Joan only the son David with Helen as probable. Lloyd's History of Wales [...] includes a chart so drawn as to make the maternity of the daughters questionable, and omits Angharad altogether. Prof. Thomas Jones Pierce in his article on Joan in the Dictionary of Welsh Biography names David, but does not mention the daughters at all; but then his cited sources are ony DNB and Lloyd's History of Wales in earlier editions. The correspondence of the writer with Sir Anthony Richard Wagner, Garter Principal King of Arms, however, indicates that all these daughters, with the exception of Gwladys, have been accepted by Major Francis Jones, best known authority on Welsh pedigrees, and based on British Museum Manuscript Add. 15041, on folio 12a, which shows Joan to be mother of David, Gwenlian, Angharad, and Margaret. It is interesting to note that [Complete Peerage] 9:276, under Mortimer of Wigmore, identifies Gwaldys as Joan's daughter."

    Later in the same publication, TAG 41:22, Sheppard provides an addendum, first quoting a letter from E. D. Jones, Librarian of the National Library of Wales: "Robert Vaughan of Hengwrt, a reliable seventeenth century authority, makes Gwladys full sister to Gruffydd, therefore the daughter of Tangwystl. He makes Gwenllian, Angharad and Marred (Margaret) to be daughters of Joan. I am inclined to accept the view that Gwladys Ddu was the daughter of Tangwystl, but in the absence of contemporary records it is not wise to be too dogmatic." Sheppard then continues: "Sir Anthony Richard Wagner KCVO, Garter Principal King of Arms, in a letter to the writer dated 24 Sept. 1964, states that he would accept Margaret as Joan's daughter and, presumably, the other daughters, except Gwladys. He refers to Major Francis Jones and the previously cited British Museum Additional MS, which shows Joan to be mother of David, and points out that the chronology also fits."

    Peter C. Bartrum's Welsh Genealogies (1974-83, searchable here; use the search term "Gruffudd ap Cynan 04"), gives Tangwystl as the mother of Gwladus and Joan as the probable mother of Margaret.

    William Addams Reitwiesner's "The Children of Joan, Princess of North Wales," in The Genealogist 1:80, Spring 1980, argues that we have no certain basis for regarding Joan as the mother of any of Llywelyn's daughters.

    On 9 April 1999, Douglas Richardson posted the following to SGM: "As for the Welsh tradition that any son, legitimate or otherwise, could make a claim to succeed Llywelyn, you may recall that Llywelyn and his son, David, went out of their way to have David recognized as Llywelyn's sole heir, to the exclusion of Llywelyn's illegitimate sons. To accomplish this, they had Llywelyn's wife, Joan, legitimized. The legitimization of Joan was no small feat seeing she was surely born out of wedlock to King John's mistress. Also, they sent David to England to be recognized as Llywelyn's sole heir by the English overlord, David's own uncle, King Henry III. Interestingly, the records of this trip show that David was accompanied by none other than his sister, Gladys. Due to the nature of this trip, it seems odd that Gladys would accompany David on this trip, UNLESS she too was a legitimate child of Llywelyn and Joan. These two pieces of evidence convince me that Gladys was legitimate." We find Richardson persuasive on this poimt.

He d. 1 May 1230, being hanged by Llewelyn abovenamed. His widow d. before 1246." [Complete Peerage I:22, as corrected in Volume XIV.]

    Hanged by Llewelyn, Prince of Wales, after intrigues with Llewelyn's wife.

    "He was discovered in Joan's chambers, accused of being her lover, and promptly and publicly hanged. While the story that William and Joan were lovers has been generally accepted, the Annals of Margam (in T. Gale, ed , Historiae Britannicae et Anglicanae Scriptores XX (Oxford, 1687), 2-18, [anno] MCCXXX) implies that the 'intimacy' was devised by Llywelyn to avenge himself on William for political injuries inflicted not only by William but by the entire Braose family; the execution was hailed by the Welsh as a vindication of a blood-feud against the Braoses dating from at least 1176. Indeed, shortly after the execution Llywelyn wrote to William's widow Eva and to William Marshal, Earl of Pembroke, Eva's brother, stating, in effect, that so far as he was concerned, the intended marriage between Llywelyn's son Dafydd and Eva's daughter Isabella could go forward as planned, and that he could not have prevented the Welsh magnates from taking their vengeance. See J. Goronwy Edwards, Calendar of Ancient Correspondence concerning Wales (Board of Celtic Studies of the University of Wales, History and Law Series, 2)(Cardiff, 1935), pp 51-52, nos. XI.56a, 56b. The marriage in fact took place three months later." [William Addams Reitwiesner, "The Children of Joan, Princess of North Wales," The Genealogist 1:80, Spring 1980.]
