John de Mowbray, 4th Baron Mowbray

John de Mowbray, 4th Baron Mowbray (24 June 1340 – 1368) was an English peer. He was slain near Constantinople while en route to the Holy Land.

Family
John de Mowbray, born 25 June 1340 at Epworth, Lincolnshire, was the son of John de Mowbray, 3rd Baron Mowbray, of Axholme, Lincolnshire, by his second wife, Joan of Lancaster, sixth and youngest daughter of Henry, 3rd Earl of Lancaster.

Career
He and twenty-six others were knighted by Edward III in July 1355 while English forces were at the Downs before sailing to France. In 1356 he served in a campaign in Brittany. He had livery of his lands on 14 November 1361; however his inheritance was subject to the dower which his father had settled on his stepmother, Elizabeth de Vere. By 1369 she had married Sir William de Cossington, son and heir of Stephen de Cossington of Cossington in Aylesford, Kent; not long after the marriage she and her new husband surrendered themselves to the Fleet prison for debt. According to Archer, the cause may have been Mowbray's prosecution of his stepmother for waste of his estates; he had been awarded damages against her of almost £1000.

In about 1343 an agreement had been made for a double marriage between, on the one hand, Mowbray and Audrey Montagu, the granddaughter of Thomas of Brotherton, and on the other hand, Mowbray's sister, Blanche, and Audrey's brother, Edward Montagu. Neither marriage took place. Instead, about 1349 a double marriage was solemnized between, on the one hand, Mowbray and Elizabeth Segrave, and on the other hand, Mowbray's sister Blanche, and Elizabeth Segrave's brother John, Pope Clement VI having granted dispensations for the marriages at the request of the Earl of Lancaster in order to prevent 'disputes between the parents', who were neighbours. Mowbray had little financial benefit from his marriage during his lifetime as a result of the very large jointure which had been awarded to Elizabeth Segrave's mother, Margaret, Duchess of Norfolk, who lived until 1399. However, when Elizabeth Segrave's father, John de Segrave, 4th Baron Segrave, died on 1 April 1353, Edward III allowed Mowbray to receive a small portion of his wife's eventual inheritance. Estate accounts for 1367 indicate that Mowbray enjoyed an annual income of almost £800 at that time.

Mowbray was summoned to Parliament from 14 August 1362 to 20 January 1366. On 10 October 1367 he appointed attorneys in preparation for travel beyond the seas; these appointments were confirmed in the following year. He was slain by the Turks near Constantinople while en route to the Holy Land. A letter from the priory of 'Peyn' written in 1396 suggests that he was initially buried at the convent at Pera opposite Constantinople; according to the letter, 'at the instance of his son Thomas' his bones had now been gathered and were being sent to England for burial with his ancestors.

His will was proved at Lincoln on 17 May 1369. His wife, Elizabeth, predeceased him in 1368 by only a few months.

Marriage and issue
Mowbray married, by papal dispensation dated 25 March 1349, Elizabeth de Segrave (born 25 October 1338 at Croxton Abbey), suo jure Lady Segrave, daughter and heiress of John de Segrave, 4th Baron Segrave (d.1353), by Margaret, daughter and heiress of Thomas of Brotherton, son of Edward I.

They had two sons and three daughters:

John de Mowbray, 1st Earl of Nottingham (1 August 1365 – before 12 February 1383), who died unmarried, and was buried at the Whitefriars, London.
Thomas de Mowbray, 1st Duke of Norfolk.
Eleanor Mowbray (born before 25 May 1364), who married John de Welles, 5th Baron Welles.
Margaret Mowbray (d. before 11 July 1401), who married, by licence dated 1 July 1369, Sir Reginald Lucy (d. 9 November 1437) of Woodcroft in Luton, Bedfordshire.
Joan Mowbray, who married firstly Sir Thomas Grey (1359 – 26 November or 3 December 1400) of Heaton near Norham, Northumberland, son of the chronicler Sir Thomas Grey, and secondly Sir Thomas Tunstall of Thurland in Tunstall, Lancashire.[16]

John married de Segrave, Baroness Elizabeth on 25 Mar 1349 in Lincoln, Lincolnshire, England. Elizabeth (daughter of de Segrave, Sir John and de Brotherton, Margaret) was born on 3 Oct 1338 in Croxton Abbey, Croxton Kerrial, Leicestershire, England; was christened on 2 Nov 1338 in Croxton Abbey, Croxton Kerrial, Leicestershire, England; died on 2 Apr 1368 in Epworth, Lincolnshire, England; was buried after 2 Apr 1368 in Croxton Abbey, Croxton Kerrial, Leicestershire, England.

He succeeded his father as Lord Mowbray de iure when the latter was hanged in 1322. However, his father's estates were confiscated for supporting the rebellion of Thomas Earl of Lancaster in his rebellion. John de Mowbray was imprisoned in the Tower 26 Feb 1322. His inheritance was restored on the accession of King Edward III. A manuscript record of the Mowbray family states that “Johannes filius [Johannis]” was buried “apud Bedford”[735].

Mowbray. Barony by Writ. III. 1322. John (de Mowbray), Lord Mowbray, son and heir, born 29 Nov. 1310, at Hovingham, Yorks, and baptized in All Saints Church there. On 26 Feb. 1321/2 he was imprisoned in the Tower. On the accession of Edward III his inheritance, of which many grants had been made, was restored, and on 3 Feb. 1326/7 the wardship of Axholme was granted to Joan, Countess (de Warenne) of Surrey. On 5 Apr. 1327 he was summoned for service against the Scots, and on 22 Apr. was ordered, as lord of Gower, to bring his men from Wales personally to Newcastle. On 27 July, the King having taken his homage, he had livery of all his father's lands (excepting those of the Templars), though he was still under age.

He was summoned to Parliament from 10 Dec. 1327 to 20 Nov. 1360, and frequently to Councils from 1328 to 1359. He is said to have been present at Amiens, 6 June 1329, when Edward III did homage to the King of France. He was at Swansea on 1 Aug. 1332, and at Fountains on 24 Aug. From now on he was put on numerous commissions of array, oyer and terminer, and in July assisted in the retaking of Berwick. He was at Oystermouth, in Gower, on 16 Aug. 1334, but appears to have have returned to Scotland to guard the Border. In Mar. 1336/7 two ships were provided for him for going to Scotland, and he had remission of 300 marks owing to the Exchequer. In Oct. 1338 he was ordered to take all his forces to Sussex to defend the coast, and was continuously in the King's service up to the summer of 1341, being ordered from Sussex to Scotland again at Michaelmas 1339, and appointed, 15 Apr. 1340, Keeper of Berwick-on-Tweed for a year, and justice in the parts of Scotland occupied by the King of England. In Nov. 1342 the King, who had arrived at Brest in Oct., ordered him to furnish men-at-arms and archers as quickly as possible for the campaign in Brittany, and to send them on if he could not come himself. On 20 Nov. he was summoned to a Council with Prince Edward, and on 13 May 1343, as lord of Gower, was ordered to be intendant to the Prince, who had been created Prince of Wales. On 22 July 1345 he was at Byland Abbey, and in July 1346 he was again in garrison at Berwick, and was ordered to select and send for the French campaign 150 Welshmen from Gower; he was also directed to send a deputy to the Parliament summoned for Sept., as he was needed on the Scottish border. At the defeat of the Scots at Nevill's Cross, Durham, 17 Oct. 1346, he led "the 3rd
battle" with the Bishop of Lincoln, and was among the Northern magnates who received the King's thanks for their services then. With other Northern magnates he was summoned, 10 Dec., to a Council at Westminster on Scottish affairs, and shortly after Easter 1347 returned to Scotland on service.

He was summoned to Councils again in Mar. 1350, and in 1352 and 1353. He is said to have taken part in the naval defeat of the Spaniards off Winchelsea, 29 Aug. 1350. From 1351 onwards he was a justice of the peace in Lincs and other counties. He was one of the five commissioners appointed in May 1352 for the defence of the Yorkshire coast against an expected invasion, and as lord of Gower was ordered to provide 30 Welshmen. In the spring of 1355, as John de Mowbray, baron, he was present with his son (as John de Mowbray, nephew of the Earl of Lancaster) at the confirmation of the statutes of St. Mary's, Leicester. Towards the end of that year he was in Scotland with the King, and on 20 Jan. 1355/6 witnessed the surrender by Baliol of his claim to the Scottish crown in favour of Edward. Having lost the lordship of Gower, he from about this time styled himself "lord of the Isle of Axholme and of the honour of Bramber." He was one of those who took the oath that the treaty of Bretigny should be observed.

He married, firstly, John, sixth and youngest daughter of Henry, Earl of Lancaster. She died 7 July (? 1349), and is said to have been buried before the high altar at Byland. He married, secondly, Elizabeth, widow of Hugh de Courtenay (dead 1349), son and heir of Hugh, 2nd Earl of Devon, and daughter of John (de Vere or Veer), Earl of Oxford, by Maud, widow of Robert FitzPayn, and second daughter of Bartholomew, Lord Badlesmere. He died 4 Oct. 1361.

His widow married, before 18 Jan. 1368/9, Sir William de Cosynton, son and heir of Stephen de Cosynton, of Cosynton (in Aylesford), and Acrise, Kent, a kngiht of Prince Edward. She died Aug. or Sep. 1375. He was living 6 July 1380.

John married Plantagenet, Lady Joan of Lancaster between 8 Mar and 12 Jun 1327. Joan (daughter of Plantagenet, Henry and de Chaworth, Maud) was born in 1312 in Grismond or Grosmont Castle (destroyed), Grosmont, Monmouthshire, Wales; died on 15 Jul 1349 in Byland Abbey, Yorkshire, England; was buried after 15 Jul 1349 in Byland Abbey, Yorkshire, England.

From Life Sketch:

Joan of Lancaster was born circa 1312 at Grosmont Castle in Monmouthshire. Her father was the son of Edmund Crouchback, 1st Earl of Lancaster and Blanche of Artois, Queen Dowager of Navarre, a granddaughter of Louis VIII of France and Blanche of Castile. Her paternal great-grandparents were Henry III of England and Eleanor of Provence. Joan was thus doubly descended from Henry II and Eleanor of Aquitaine. Joan's mother was a half-sister of Edward II's favorite, Hugh le Despenser the Younger, through the remarriage of Maud's mother, Isabella de Beauchamp, to Hugh le Despenser, 1st Earl of Winchester. Joan had one brother, Henry of Grosmont, 1st Duke of Lancaster, and five sisters, Blanche, Baroness Wake of Liddell, Isabel, Abbess of Amesbury, Maud, Countess of Ulster, Eleanor, Countess of Arundel and Warenne, and Mary, Baroness Percy. Joan's niece, Elizabeth de Burgh, Countess of Ulster, married Lionel of Antwerp, Duke of Clarence, the second surviving son of Edward III and Philippa of Hainault, a marriage that would create a line of descent to strengthen the Yorkist claim to the throne in the Wars of the Roses. Another niece, Blanche of Lancaster, married the third surviving son of Edward III, John of Gaunt, and became the mother of the first Lancastrian king of England, Henry IV.

From Life Sketch

Henry, 3rd Earl of Leicester and Lancaster (c. 1281 – 22 September 1345) was an English nobleman, one of the principals behind the deposition of Edward II of England.

He was the younger son of Edmund Crouchback, 1st Earl of Lancaster, Earl of Leicester, who was a son of King Henry III by his wife Eleanor of Provence. Henry's mother was Blanche of Artois, Queen Dowager of Navarre.

Henry's elder brother Thomas, 2nd Earl of Lancaster, succeeded their father in 1296, but Henry was summoned to Parliament on 6 February 1298/99 by writ directed to Henrico de Lancastre nepoti Regis ("Henry of Lancaster, nephew of the king", Edward I), by which he is held to have become Baron Lancaster. He took part in the Siege of Caerlaverock in July 1300.

Petition for succession and inheritance
After a period of longstanding opposition to King Edward II and his advisors, including joining two open rebellions, Henry's brother Thomas was convicted of treason, executed and had his lands and titles forfeited in 1322. Henry did not participate in his brother's rebellions; he later petitioned for his brother's lands and titles, and on 29 March 1324 he was invested as Earl of Leicester. A few years later, shortly after his accession in 1327, the young Edward III of England returned the earldom of Lancaster to him, along with other lordships such as that of Bowland.

Revenge
On the Queen's return to England in September 1326 with Roger Mortimer, 1st Earl of March, Henry joined her party against King Edward II, which led to a general desertion of the king's cause and overturned the power of Hugh le Despenser, 1st Earl of Winchester, and his namesake son Hugh the younger Despenser.

He was sent in pursuit and captured the king at Neath in South Wales. He was appointed to take charge of the king and was responsible for his custody at Kenilworth Castle.

Full restoration and reward
Henry was appointed "chief advisor" for the new king Edward III of England, and was also appointed captain-general of all the king's forces in the Scottish Marches. He was appointed High Sheriff of Lancashire in 1327. He also helped the young king to put an end to Mortimer's regency and tyranny, also had him declared a traitor and executed in 1330.

Loss of sight
In about the year 1330, he became blind.

Henry married de Chaworth, Maud before 2 Mar 1297. Maud (daughter of de Chaworth, Patrick V and de Beauchamp, Isabella) was born on 2 Feb 1282 in Kidwelly Castle, Kidwelly, Carmarthenshire, Wales; died on 3 Dec 1322 in Mottisfont Priory, Mottisfont, Hampshire, England. [Group Sheet] [Family Chart]

Notes:

Maud de Chaworth (2 February 1282 – 3 December 1322) was an English noblewoman and wealthy heiress. She was the only child of Patrick de Chaworth. Sometime before 2 March 1297, she married Henry, 3rd Earl of Lancaster, by whom she had seven children.

Early life
Maud was the daughter of Sir Patrick de Chaworth, Baron of Kidwelly, in Carmarthenshire, South Wales, and Isabella de Beauchamp. Her maternal grandfather was William de Beauchamp, 9th Earl of Warwick. Her father died on 7 July 1283; he was thought to be 30 years old. His paternal line was from the Castle of Chaources, now Sourches, in the Commune of St. Symphorien, near Le Mans in the County of Maine at the time of the Angevin Empire.[1] Three years later, in 1286, Isabella de Beauchamp married Hugh Despenser the Elder and had two sons and four daughters by him. This made Maud the half-sister of Hugh the younger Despenser. Her mother died in 1306.

Maud was only a year old when her father died, and his death left her a wealthy heiress. However, because she was an infant, she became a ward of Eleanor of Castile, wife of Edward I.

After Queen Eleanor's death in 1290, the King granted the right to arrange Maud's marriage to his brother Edmund Crouchback, Earl of Lancaster on 30 December 1292. Edmund arranged the marriage between Maud and one of his sons, Henry,[2] by Blanche of Artois, niece of Louis IX of France and Dowager Queen of Navarre by her fist marriage

Marriage and issue
Henry and Maud were married sometime before 2 March 1297. Henry was a little older, having probably been born in 1280 or 1281. Maud brought her father's property to the marriage, including land in Hampshire, Glamorgan, Wiltshire, and Carmarthenshire. Maud is often described as the "Countess of Leicester" or "Countess of Lancaster", but she never bore the titles as she died in 1322, before her husband received them.

Maud and Henry had seven children:

Blanche (c. 1302/1305–1380), Baroness Wake of Liddell
Henry of Grosmont (c. 1310–1361), Duke of Lancaster, one of the great English magnates of the 14th century
Maud (c. 1310 – 5 May 1377), Countess of Ulster
Joan (c. 1312–1345), married John de Mowbray, 3rd Baron Mowbray

Notes:

Isabella de Beauchamp, Lady Kidwelly, Baroness Despenser (c. 1263 – before 30 May 1306), was an English noblewoman and wealthy heiress.

Family
Lady Isabella, or Isabel de Beauchamp,[1] was born in about 1263 in Warwickshire, England. She was the only daughter of William de Beauchamp, 9th Earl of Warwick and Matilda FitzJohn[1] who married sometime between 1261 and 1268; two sisters who were nuns at Shouldham are mentioned in her father's will. She had a brother, Guy de Beauchamp, 10th Earl of Warwick who married Alice de Toeni, by whom he had seven children. Her paternal grandparents were William (III) de Beauchamp of Elmley Castle and Isabel Maudit, and her maternal grandparents were Sir John FitzGeoffrey, Lord of Shere, and Isabel Bigod.

Marriages and issue
Sometime before 1281, she married firstly Sir Patrick de Chaworth, Lord of Kidwelly in Carmarthenshire, South Wales.[2] The marriage produced one daughter:

Maud Chaworth (1282–1322), married Henry, 3rd Earl of Lancaster,[3] by whom she had seven children.
Following Sir Patrick's death in 1283, Lady Isabella had in her possession four manors in Wiltshire and two manors in Berkshire, assigned to her until her dowry should be set forth along with the livery of Chedworth in Gloucestershire and the Hampshire manor of Hartley Mauditt which had been granted to her and Sir Patrick in frank marriage by her father.

In 1286, she married secondly Sir Hugh le Despenser without the King's licence for which Sir Hugh had to pay a fine of 2000 marks.[1] He was created Baron Despenser by writ of summons to Parliament in 1295, thereby making Lady Isabella Baroness Despenser.

Together Lord and Lady Despenser had four children:

Hugh le Depenser, Lord Despenser the Younger (1286 – executed 24 November 1326),[2] married Eleanor de Clare, by whom he had issue.
Aline le Despenser (died before 28 November 1353), married Edward Burnell, Lord Burnell
Isabella le Despenser (died 4/5 December 1334), married firstly as his second wife, John Hastings, 1st Baron Hastings, by whom she had three children. Their descendants became the Lords Hastings; she married secondly as his second wife, Sir Ralph de Monthermer, 1st Baron Monthermer.[4]
Phillip le Despenser (died 1313), married as his first wife Margaret de Goushill, by whom he had issue.
Lady Despenser died sometime before 30 May 1306. Twenty years later, her husband and eldest son, favourites of King Edward II, were both executed by the orders of Roger Mortimer and Queen Isabella, who were by that time the de facto rulers of England; along with most of the people in the kingdom, they had resented the power both Despensers wielded over the King.

As her husband had been made Earl of Winchester in 1322, only after her death, Lady Despenser was never styled as the Countess of Winchester.
