      “WILLIAM DE FERRERS, Knt., 5th Earl of Derby, Constable of Bolsover Castle, 1235-6, son and heir, born about 1193. He married (1st) before 14 May 1219 SIBYL MARSHAL, died before 1238, 3rd daughter of William Marshal, Knt., 4th Earl of Pembroke (or Strigoil), hereditary Master Marshal, by Isabel, daughter of Richard Fitz Gilbert (nicknamed "Strongbow”), 2nd Earl of Pembroke (or Strigoil) [see MARSHAL 3 for her ancestry]. They had seven daughters, Agnes, Isabel, Maud, Sibyl, Joan, Agatha (wife of Hugh de Mortimer), and Eleanor. He was afflicted from youth with gout, and habitually travelled in a chariot or litter. He accompanied the king to France in 1230. He married (2nd) in or before 1238 MARGARET (or MARGERY) DE QUINCY, daughter and co-heiress of Roger de Quincy, 2nd Earl of Winchester, by his 1st wife, Ellen, daughter and co-heiress of Alan Fitz Roland, lord of Galloway, hereditary Constable of Scotland [see QUINCY 7 for her ancestry]. They had two sons, Robert, Knt. [6th Earl of Derby], and William, Knt., and three daughters, Elizabeth, Joan, and Agnes. He had livery of Chardey Castle and the rest of his mother's lands 10 Nov. 1247. He was invested with the Earldom of Derby 2 Feb. 1247/8. In 1245 he was granted respite of forest offences because he "laboured under infirmity." He presented to the church of Brington, Northamptonshire in 1250. While passing over a bridge at St. Neots, Huntingdonshire, he was accidentally thrown from his chariot sustaining broken limb bones from which he never recovered. SIR WILLIAM DE FERRERS, 5th Earl of Derby, died at Evington, Leicestershire 24 (or 28) March 1254, and was buried at Merevale Abbey, Warwickshire. His widow, Margaret, presented to the churches of Keyston, Huntingdonshire, 1255, Irchester, Northamptonshire, 1267, and Higham Ferrers, Northamptonshire, 1268, 1275. She was co-heiress in 1264 to her father, Roger de Quincy, Knt., Earl of Winchester, by which she inherited the hereditary office of Constable of Scotland, together with the manors of Groby (in Ratby) and Thurnby, Leicestershire, Ware, Hertfordshire, Keyston and Southoe, Huntingdonshire, Chinnor, Oxfordshire, etc. In 1268-9 the Prior and convent of Lenton released the church of Irchester, Northamptonshire to Margaret de Ferrers, Countess of Derby, who in turn levied a fine of it to the use of herself and her heirs. In 1270 she resigned the office of Constable of Scotland to her brother-in-law, Alexander Comyn, Knt., Earl of Buchan. In 1270 Margaret and her sisters, Ellen and Elizabeth, gave license for the election of William de Shaldeston as Prior of the Hospital of St. James and St. John at Brackley, Northamptonshire. In 1272-3 Margaret arraigned an assize of novel disseisin against John le Fauconer, of Thurcaston, and others, touching a tenement in Groby, Leicestershire. In 1273 Philip de Fifife sued her for the next presentation to the church of Fyfield, Berkshire. In 1274-5 Ellen de Quincy and Alexander Comyn and his wife, Elizabeth, sued their sister, Margaret de Ferrers, Countess of Derby, regarding possessions in Eynesbury, Huntingdonshire. On the assignment of Quincy dower lands in 1275, Margaret was assigned a third part of the manor of Southoe Ferrers, Huntingdonshire, together with a third part of the chief messuage. In 1275-6 William de Karuill' arraigned an assize of mort d'ancestor against her touching a messuage and land in Brampton, Northamptonshire. Sometime in the period, 1275-9, she acquired the one-third share of the same manor assigned to her sister, Elizabeth Comyn, thus increasing Margaret's share to two-thirds. In 1276 Margaret had letters of protection, she then going to Scotland. In 1277-8 Alice widow of John de Kent arraigned an assize of novel disseisin against her and others touching a tenement in Chardey, Staffordshire. About 1281 Margaret de Ferrers, Countess of Derby, Ellen la Zouche, and Alexander Comyn, Earl of Buchan, and his wife, Elizabeth, sued Ranulph son of Robert de Neville and his wife, Euphame, regarding 11-1/2 virgates in Syston, Leicestershire. Margaret, Countess of Derby, died shortly before 12 March 1280/1, on which date custody of all lands late of the said Countess Margaret were granted by the king to Richard Fukeram to hold during pleasure, so that he cultivate and sow them and answer for the issues at the Exchequer. In 1282 custody of the manor of Southoe, Huntingdonshire late of Margaret, Countess of Derby, deceased was granted by the king to John de Aese, Vicomte of Tartas to hold during the minority of the heirs. The same month custody of the manor of Keyston, Huntingdonshire late of Margaret, Countess of Derby, deceased was likewise granted by the king to John de Byu.elard to hold during the minority of the heirs. In 1281 the king ratified the demise of John de Aysse, Vicomte of Tartas, to Baldwin Wake and Hawise his wife of custody of the manor of Southoe, Huntingdonshire which he had of the gift of the king by the extent of £40 2s. 8d. yearly to hold during the minority of the heirs of Margery, Countess of Derby.

He married (1st) after 8 Nov. 1227 HAWISE FITZ GEOFFREY, daughter of Geoffrey Fitz Peter, Knt., Earl of Essex, by his 2nd wife, Aveline, daughter of Roger de Clare, Earl of Hertford [see ESSEX 2 for her ancestry]. Her maritagium apparently included the manor of Streadey, Berkshire. He had license in 1233 to cut oaks in his wood at Tymeworth for his house at Streadey, Berkshire. They had one son, John, and three daughters, Alice, Juliane (wife of William de Lisle), and Lucy. He accompanied King Henry III to France in 1230 and to Wales in 1231. His wife, Hawise, died before 1243. He married (2nd) in or before 1243 (without license) ISABEL DE FERRERS, widow of Gilbert Basset, of Wycombe, Buckinghamshire, Greywelt, Hampshire, etc., and daughter of William de Ferrers, 5th Earl of Derby, by Sibyl, 3rd daughter of William Marshal, Knt., 4th Earl of Pembroke (or Striguil), hereditary Master Marshal [see FERRERS 7 for her ancestry]. They had two sons, William and [Master] James [parson of Brompton, Yorkshire]. His wife, Isabel, was co-heiress in 1245 to her uncle, Anselm Marshal, 9th Earl of Pembroke. In 1246 he gave the manor of Axminster, Devon to his foundation of Newenham Abbey, Devon. Sometime in or after 1254, he made a grant to the convent of Bath for the soul of his son, John, lately dead, and other relatives. He was also a benefactor to the canons of Bruton and the abbey of Cleeve. He gave two charters to the townsmen of Dunster. SIR REYNOLD DE MOHUN died at Tor Mohun, Devon 20 Jan. 1257/8, and was buried at Newenham Abbey, Devon. His widow, Isabel, died 26 Nov. 1260.
