The pedigree shows the following descent:--Lionel Plantagenet, Duke of Clarence, third son of King Edward III. and Philippa of Hainault, left by Elizabeth de Burgh (daughter of William de Burgh, Earl of Ulster, and Maud Plantagenet, second daughter of Henry, third Earl of Lancaster) an only child, Philippa, married to Edmund Mortimer, third Earl of March (_Esc._, 5 Ric. II., No. 43.). The eldest daughter of Philippa Plantagenet by the Earl of March was Elizabeth Mortimer, who married the renowned Hotspur, Henry Lord Percy, son and heir apparent of Henry Lord Percy, created Earl of Northumberland, 16th July, 1377, K. G. Hotspur was slain at the battle of Shrewsbury, 7th September, 1403, _v.p._ His widow experienced the revengeful persecution of King Henry (Rymer, viii. 334., Oct. 8, 1403), and died, leaving by her said husband one son, Henry, who became second Earl of Northumberland, and an only daughter, Elizabeth de Percy, who married firstly, John, seventh Lord Clifford of Westmoreland, who died 13th March, 1422 (_Esc._, 10 Henry V., No. 37.), and secondly, Ralph Neville, second Earl of Westmoreland (_Esc._, 15 Hen. VI., No. 55.), by whom she left an only child, Sir John Neville, Knight, who died during his father's lifetime, 20th March, 1451, _s.p._ (Will proved 30th March, 1451.) Lady Elizabeth de Percy, who died in October, 1436, left by her first husband, the Lord Clifford, three children: Thomas, eighth Lord Clifford; Henry, her second son; and an only daughter, Mary, who became the wife of Sir Philip Wentworth, Knight. The Lady Mary Clifford, who must have been born before 1422 (her father having died in that year), was probably only a few years older than her husband Sir Philip, the issue of a marriage which took place in June, 1 Henry VI., 1423 (_Cott. MSS. Cleop._, F. iv. f. 15.); she was buried in the church of the Friars Minor at Ipswich, where her mother-in-law directed a marble to be laid over her body. Sir Philip's father, Roger Wentworth, Esq. (second son of John Wentworth of North Elmsal, a scion of the house of Wentworth of the North), had married in 1423 Margery Lady de Roos, widow of John Lord de Roos, sole daughter and heiress of Elizabeth de Tibetot, or Tiptoft (third daughter and co-heir of Robert, Lord de Tibetot), and of Sir Philip le Despenser Chivaler (_Esc._, 18 Edw. IV., No. 35.). By this marriage came, first, Sir Philip Wentworth, Knight, born circa 1424, and married when about {43} twenty-three years of age, in 1447; he was slain in 1461, and attainted of high treason in the parliament held 1 Edw. IV.; second, Henry Wentworth of Codham, in the county of Essex; third, Thomas Wentworth Chaplain; and fourth, Agnes, wife of Sir Robert Constable of Flamborough (_Harl. MSS._, 1560. 1449-1484, and will of Margery, Lady de Roos, proved in the Prerogative Court of Canterbury, 28th May, 1478). Sir Philip, about the year 1447, as before stated, married the Lady Mary Clifford (_Harl. MSS._, 154. and 1484.),
