Leicestershire Brabazons

by Jan Barnes

The following is a Brabazon lineage for the period 1200-1400. It was mostly researched from Leicestershire Medieval Village Notes, collected and published (late 1920s-early 1930s) by George F. Farnham. He also wrote Leicestershire Medieval Pedigrees (1925). Wyggeston Hospital Records, collected and published by A. Hamilton Thomson in 1933 provide some extra information on the Brabazons living 1400-1600. More later

Farnham and Thompson were keen members of the Leicestershire Archaeological Society. They thought their society should concentrate on research rather than happy picnics at historical sites.

Part 1

In the middle years of the 13th century Amice (living 1279), an heiress with land in Mousely married a member of the Brabazon family. Their children were Roger (the judge), Matthew, Joan, Anabil and Emma. When Roger died in 1317 his full title was Sir Roger le Brabazon, of Museleye, knight.

Between 1281 and 1284 Roger married an heiress, the widow of William de Keleby. (1) She was Beatrice (living 1297), daughter of William le Graunt and Aubrey de Sproxton. (2) Through her mother, Beatrice was co-heir to her uncle, John de Sproxton. (3) She and her sister were also co-heirs to their father and to his brother, Mancel Byset. (4) Roger and Beatrice had no children.

Matthew le Brabazon, the second son of the family, was married to Sarra. They had no children.

Joan was probably the oldest of the three sisters. She was married to another Brabazon, possibly a Brabazon of Saddington in the south of Leicestershire.

Anabil was married to a de Outheby, probably Robert de Outheby.

When Sir Roger died (5) some of the manors, which he held, passed to Beatrice's relations because they were her inheritance. Roger had held those manors only for his lifetime. (6)

Shortly before his death, with the king's assent, he gave the manor of Sibertoft in Northamptonshire to his nephew Thomas le Curzon, his sister Emma's son. (7) This manor was held in chief 'by service of finding a footman with bow and arrows for forty days in the king's army at the cost of the manor'.

Land in Mouseley and Gormondelegh went to his brother Matthew who was his 'right heir'. As was customary in those days the three sisters were co-heirs after Matthew and Sarra died.

Probably before his death he gave the manor of Sproxton (8) and also land in (9) Garthorpe to a kinsman named William Brabazon and to William's wife Joan. A charter says that (10) William was Sir Roger's nephew. William and Joan and their heirs held Sproxton and Garthorpe from Sir Roger's heirs by knight's service paying one penny at Michaelmas yearly. (11) Eastwell was not mentioned. I suggest that the manor of Eastwell was owned by Joan's descendants.

Eastwell

Joan Brabazon's eldest child and heir was also called Roger Brabazon. He was known as Roger Brabazon the younger. He was a solicitor or similar man of law, many times appointed attorney for Blanche, Queen of Navarre as well as her husband Edmund, the King's brother. (14) This could be the Roger Brabazon who was knighted in 1300 and is most likely the Roger Brabazon who held 1/2 knights fee in Eastwell 20 May 1300 (12).

Roger the younger and his wife Elizabeth held land in Eastwell about 1293 (13) Roger also held land in Saddington in 1292. (14) This Roger died before his uncle, sometime between 1300 and 1310. (15) Elizabeth held Eastwell for many years after his death (16)

Roger the younger had a son and heir named Thomas, born about 1299 (17) who was Thomas Brabazon of Eastwell (18) and possibly also Thomas Brabazon of Saddington (19)

Thomas had a son, John Brabazon. This was probably John Brabazon of Eastwell, knight who was witness to a grant of the manor of Wyfordby, 12 December 1352. (20)

John had a son, also named John (living 1391) Lord of Eastwell. He was married to Elizabeth. (21)

If this is the Woodford Chartulary as reproduced by Nichols in the History and Antiquities of the County of Leicestershire, there are a number of statements on p.324 which don't agree with the official records, so he might not have been a nephew.

The lineage was recited in court in 1370 when the last named John Brabazon and his relative Thomas de Outheby attempted to recover the wardship of the Sproxton heir.

Thomas de Outheby and John Brabason of Estwell v John Botiler of Eyton, in a plea that he render them the custody of the land and heir of Joan who was the wife of William de Wodeford, which belongs to them because Joan held her land of them by knight service.

They say that a certain Roger Brabazon was seised of the manor of Sproxton in his desmesne as of fee in the time of king Edward I, which he held of the prince of Wales, as of his honour of Huntingdon, by homage, fealty and 20s to the scutage, more or less, when it happens; which Roger afterwards enfoeffed William Brabazon and Joan his wife, to hold the said manor to them and their issue, of the said Roger and his heirs, rendering to the same Roger and to his heirs one penny at Michaelmas yearly.

And from Roger, who died without issue, the right went to Matthew Brabazon as brother and heir and from Matthew, who died without issue, the right descended to certain Joan, Anabil and Emma as sisters and heirs.

And from Joan the right of her purparty descended to a certain Roger as son and heir, and from Roger to Thomas as son and heir, and from Thomas to John as son and heir, and from John to John Brabazon who now demands, as son and heir.

And from Anabil the right of her purparty descended to Roger as son and heir, who died without issue, when the right came to Theobald as brother and heir, and from Theobald to Thomas Outheby, who now demands as son and heir

And from Emma the right of her purparty descended to Thomas as son and heir, and from Thomas to William Curson as son and heir.

And from the said William Brabazon the manor descended to John as son and heir, and from John to Joan who was the wife of William de Wodeford, as daughter and heir.

William de Wodeford after the death of the said Joan, held the said manor by the courtesy of England, during which time William Curson, son of Thomas, son of Emma, by his writing granted to William de Wodeford and his heirs all his right and claim to the said manor and rent. John the son of Joan was in the custody of Thomas de Outheby and John Brabazon until they were disseised by John Botiler, by which disseisen Thomas and John Brabason say that they are damaged 1,000.

Sproxton

The identity of William Brabazon who was given Sproxton and Garthorpe has puzzled researchers. If he was Sir Roger's nephew he could have been the son of an older half brother or he could have been a deserving younger son of his sister Joan.

In 1292 Sir Roger Brabazon and Beatrice his wife granted 30 librates of land (about 1,500 acres) in Sproxton Saxeby and Pykwell to Thomas Brabazon and his heirs. (23) He could have been an older brother or Joan's husband.

In 1297a Thomas Brabanzun was parson of the church of Hungerton. (24)

According to Nichols, In 1302 Sir Roger paid 200 marks to Beatrice's co-heirs for their rights to the manor of Sproxton. He could have granted the manor to William as early as 1302.

22. Farnham, Vol II, p.181, De Banco Roll 438, Easter 44 Ed III.
23. Farnham, Vol IV, p.126, Fine, Michaelmas 20 Ed I. The land was Beatrice's co-inheritance. .
24. Calendar of Chancery Rolls, Various, 1277-1326, p.41, 25 Ed I.

In 1306 William Brabazon was knighted with 266 others at Whitsuntide, on the occasion of the knighting of Edward Prince of Wales, afterwards Edward II. William was a Knight of the Bath.

This could be William who was given Sproxton.

Part 2 (1400-1600)

Nicholas Brabazon of Estwell Esquire, living 1415, is the next in the Eastwell line. (1)

He was followed by John Brabazon of Estwell 'gentylman' (2) who married Maud (Matilda) Jervis, daughter and co-heir of Nicholas Jervis of Harby. She died 14 October 1490. (3) Nicols says John held a knight's fee in Eastwell in 1461 from John Moubray, Duke of Norfolk. (4)

John is said to have died at the Battle of Bosworth (22 August 1485) but according to a record in Farnham he was dead before the battle. Maud was a widow near the beginning of that year.(5) John was buried in the chapel of the parish church of St Goodlack of Estwell.

They had at least six children, Roger the heir, Adam of Allexton, William of Estwell, Alexander of Eaton, Isabel and John or possibly Thomas or both.

(6) Farnham, Vol II, p.188. In his grandson John's will, 1548.

John and Maud's oldest son, Roger Brabazon, died at Bosworth, intestate, supposedly on 12 August 1 Hen VII, (1486) (7) but the date given by Farnham is nearly a year after the battle. However, if somebody has made an adjustment to allow for the ten-day difference between the Julian and Gregorian calendars the date would be the 22nd August 1 Hen VII, the first day of Henry's reign and the date of the battle.

At his death Roger was seized of 10 messuages and 10 virgates of land in Estwell which he held by knight service from the Duchess of Norfolk. (8) She was John de Mowbray's widow. The Duke of Norfolk who was slain on Bosworth Field was Sir John Howard.

Roger's wife Margaret, remarried to James Huddleston.

He left three children, Roger his heir,(9) who was a minor, Joan and Margaret

The heir, Roger, married Isabel but died probably quite young, about 1494, with no children and his inheritance passed to his two sisters, Joan and Margaret who by then had both married into the Sherard family. (10)

Two of John and Maud's children, Adam and Isabel, probably didn't marry.

Alexander of Eaton's school age children are mentioned in Adam Brabazon's will (1509) but not by name. Alexander was living in 1524. (11)

The situation regarding the manor and lands of Eastwell becomes confusing about this time. Court cases describe disputes about land rights and enclosures, the abduction of an heiress etc. Several involve William Brabazon, another of John and Maud's sons.

William farmed part of Eastwell. He is described as William Brabazon of Estwell in deeds made about 1519-20 and in his will (proved 1521). His wife was Agnes. He had a son and heir called John and daughters Margaret, Elizabeth, Joan, Margery & Isabel who were probably all underage when he died.

(8) Inquisition Post Mortem, Hen VII, Second Series 1, 1898, p.268, Maud Brabshen, widow (1490).
(9) There has been some confusion over the lineage because Maud's inquisition after her death is incorrectly recorded. The Roger mentioned in her inquisition in 1490 was underage and therefore must have been her grandson Roger, not her son who was already dead in 1485-6 and married with children. See George F.Farnham, Leicestershire Medieval Pedigrees, 1925, p.80-82 and the inquisition below
Maud Brabshen, widow, writ 22 Oct inq. 2 Nov., 6 Hen VII.
One Nicholas Jerves of Hardby, 'gentilman' gave the undermentioned rents, messuages, and land to John Brabesshon and the said Maud his wife, daughter of the said Nicholas, in tail. She survived the said John, and died 14 Oct., 6 Hen VII. Roger Brabesshon, aged 14 and more is the son and heir of the said Roger (sic) and Maud; he is in the custody of the Lady Elizabeth, Duchess of Norfolk, because the said Roger (sic) his father was seised at his death of 10 messuages and 10 virgates of land in Estwell, co Leicester, which he held of the Duchess by knight service.
(10) Farnham, Vol II, p.183, De Banco Rolls 927, Hilary 9 Hen VII and 930, Michaelmas following. (1494). Isabel obtained dower from Roger's sisters and their husbands which included 1/3 of the manor of Eastwell as well as other lands and rents in Eastwell Harby, Mousely and Scalford. A widow could ask for 1/3 of her husband's estate to keep her for her lifetime.

(13) A.Hamilton Thompson, Wyggeston Hospital Records, Part II, 1933, p.569.

William's son John also lived at Eastwell. This family had farm leases, which probably came to an end sometime after John died, leaving an only daughter, Rose. He was also buried at St Goodlack's Chapel, 1548-49.(15)

William Brabazon's daughter, Margery seems to have married Sir Edward Moore of Mellifont. (16)

Roger's daughter, Joan Brabazon, was apparently abducted by Sir George Hastings whilst still married to Robert Sherard and their child was said to be illegitimate. About 1515 Hugh Sherard disputed the Hastings inheritance on these grounds. (17)

In 1537 William Brabazon made an agreement with the Hastings. This was Sir William who went to Ireland. Before the death of his uncle he was called William Brabazon the younger. (18) He doesn't appear to have been knighted at this stage.

William Brabazon, esquire gave 80s to the king for licence to agree with Hugh Hastynges, knight, and Katherine, his wife, and Martin Hastynges, esq, and Anne, his wife, in a plea of covenant of the manor of Wilmercote, co Warwick and the manors of Estwell and Hardeby and 20 messuages, 10 tofts, 400 acres of land, 70 of meadow, 200 of pasture, 10 of wood and 40s rent in Estwell, Hardeby, Stathern, Skalford, Braunston, Harston, Flekeney, Sadyngton, and Mouseley, co Leicester. (19)

When Sir William Brabazon died his inquisition said :-

The jury say that William Brabazon, knight was seised long before his death of the manor of Estwell and a windmill, 16 messuages, 8 cottages, 20 acres of land, 60 of meadow, 40 of pasture, and 20s rent in Estwell, Harby, Eyton, and Wykham. Also of the manor of Mowsell, 4 messuages, 2 cottages, 100 acres of land, 20 of meadow, 40 of pasture and 6s rent in Mouseley and Wylmercote.

The manor and lands in Estwell were held of the king, as of the duchy of Lancaster by a fourth part of a knight's fee, and worth beyond reprises 21 3s. 4 d

The manor of Mouseley was held of the king, as of his honour of Leicester, parcel of the duchy of Lancaster, by a third part of a knight's fee, and worth 9 7s 4d.

William Brabazon died on 10 June, 6 Edward VI, 1552. Edward Brabazon is his son and heir and aged 3 years and 3 months at his father's death.

Hence to Ireland

John or Thomas?

Traditionally Sir William's father was called John Brabazon, married to a Miss Chaworth, but the only Brabazon found who fits the bill is Thomas. Neither name is mentioned in Adam Brabazon's will. Of course Thomas could be a younger brother of John Brabazon who married Maud Jervis.

Maud Brabazon's sons inherited land in Wycombe and Chadwell near Melton Mowbray, from Maude and her father Nicholas Jervis. The Wyggeston Hospital Records reveal how some of the land was sold by Alexander and William between 1519 and 1521. The records also include references to Thomas Brabason.

Brabazon Lineage - Mousley and Sproxton etc.

The two Beatrices in Burke's Peerage and Sharpe's Genealogical History of the Family of Brabazon, who were married to Roger Brabazons are one person.

Her name was Beatrice le Graunt.

She was neice of John de Sproxton, not daughter.

She was neice of Mancel Byset, not sister.

Therefore there is also one less Roger. He was Sir Roger le Brabazon of Mousley, knight, died 14 June 1317 (not 1326 as in Burke).

Sarra le Brabazon, his sister in law, was the person who died 1326. (2)

Amice was the Mousley heiress. She was mother of Sir Roger le Brabazon (the judge). Her surname might not be Mousley.

1277. Agnes, who was the wife of Roger de Sadington v. Reginald son and heir of Roger de Sadington, in a plea of a third part of a toft and virgate of land in Welham; and v. John de Aungeville and Ellen his wife in a plea of a toft and 3 virgates of land in Melton; and v. Roger Brabazon and Amice, his mother, in a plea of a third part of a toft and virgate of land in Mousele as dower. (3)

Beatrice le Graunt was the Sproxton heiress.

This tree shows how Beatrice, wife of Sir Roger le Brabazon (the Judge), inherited a moiety (share) of the manor of Sproxton. She inherited half the manor from her uncle John de Sproxton and her sister Constance inherited the other half. It also shows other relations taken from the abstracts, below.

1281 William de Keleby is dead.

'Beatrice who was the wife of William de Keleby, one of the heirs of John de Sproxton'.

1284. Beatrice is remarried to Roger le Brabazon. Constance is dead. Her daughter Isabel is married to Henry de Bek.

Alice who was the wife of John de Sproxton demands dower of the abbot of Croxton and others. They call to warrant Henry de Bek and Isabel his wife, and Agnes the sister of Isabel, kinswomen and heirs of John de Sproxton, Roger le Brabazon and Beatrice his wife.....

Agnes and Isabel are under age and in the custody of John de Beke by a charter of John de Sproxton, kinsman of Agnes and Isabel and uncle of the said Beatrice, whose heirs they are........John de Sproxton gave the tenements to the abbot and the other defendants.... (5)

As can be seen from the tree and the following documents Beatrice's mother was Aubrey de Sproxton. Her father was William le Graunt.

William le Graunt had a brother called Mancel Byset.

Beatrice and Constance were Aubrey's, William's and Mancel's heirs as well as heirs of John de Sproxton.

1293.Willielmus Le Graunt alias Graund. Inquisition Post Mortem.

Est Bridgeford. The jury say that William held in co. Notts. the manor of Est Bridgeford, by the courtesy of England, of the inheritance of Beatrice the wife of Roger le Brabazon, Isabel the wife of John de Multon and Agnes the wife of John de Caltoft, heirs of Aubrey, sometime the wife of the said William le Graund, who are of full age, Duke Henry, sometime king of England, gave the manor to one Mancel Byset and his heirs to hold of the said king by homage, who afterwards enfeoffed his brother, William to hold to him and his heirs, of the said Mancel and his heirs, by homage; and the above said Beatrice and the others are the heirs of the said William, brother of Mancel, and the manor is held of the heirs of the same Mancel in chief and not of the king.

Beatrice inherited Athelington from William le Graunt and Roger did homage.
