Marriage and issue
Westmorland was first betrothed to Elizabeth Stafford (c.1497 – 30 November 1558), the eldest daughter of his guardian, Edward Stafford, 3rd Duke of Buckingham, and Eleanor Percy, with whom he is said to have been in love, and whom he was to have married before Christmas 1512. However about that time Thomas Howard made suit for her, and Elizabeth married Howard, as his second wife, before 8 January 1513. Westmorland married instead, before June 1520, Stafford's second daughter, Katherine (d. 14 May 1555). They had eighteen children, including:
Henry Neville, 5th Earl of Westmorland, who married, at a triple Neville-sibling marriage ceremony on 3 July 1536 at Holywell in Shoreditch, Anne Manners, the daughter of Thomas Manners, 1st Earl of Rutland. Their son, Charles Neville, 6th Earl of Westmorland, married, about 1563/4, Jane Howard (buried 30 June 1593), the daughter of Henry Howard, Earl of Surrey. He took part with his uncles, Christopher Neville and Cuthbert Neville, in the Northern Rebellion of 1569, was attainted in 1571, whereby all his honours were forfeited and fled to the continent, where he was involved for many years in plots on behalf of Mary, Queen of Scots, against Queen Elizabeth. He died in exile at Nieuport in Flanders on 16 November 1601.
Sir Thomas Neville.
Edward Neville.
Christopher Neville (fl. 1549–1575) of Kirkbymoorside, Yorkshire, fourth son, who married Anne Fulthorpe (d. after 1570), widow of Francis Wandesford, of Kirklington, Yorkshire, and daughter and heir of John Fulthorpe of Hipswell, Yorkshire. There was no issue of the marriage. He was attainted for treason in May 1571 for his part in the Northern Rebellion of 1569, and fled to the continent, where he died in exile.
George Neville.
Ralph Neville (d.1565).
Cuthbert Neville (fl. 1549–1569) of Brancepeth, Durham. He took part in the Northern Rebellion of 1569 with his brother, was attainted, and died in exile in the Spanish Netherlands.
Dorothy Neville (d.1548), who married, at a triple Neville-sibling marriage ceremony on 3 July 1536 at Holywell in Shoreditch, as his first wife, John de Vere, 16th Earl of Oxford, and with him had two daughters: Faith, who died as an infant, and Katherine, who married Edward Windsor, 3rd Baron Windsor. Dorothy fled the marriage in about January 1546, citing "'the vnkynde [unkind] dealing of the earl.'" In May of that year, de Vere bigamously married one of his mistresses, Joan Jockey of Earls Colne, at White Colne Church. Five men (including a knight and a lord) broke into Oxford's home while he was away and either cut Jockey's nose clean off or cut the "skin at the base of the nostrils into flaps to give her a permanently grotesque appearance," a traditional punishment for "unsocial behavior." Though Joan Jockey survived the attack, the Earl definitively 'put her away.'" In 1585, when attesting to the legitimacy of Oxford's marriage to Margery Golding, members of his household reported that "'all theise women were shaken off by the same Earle ... before the said lady Dorothie dyed'" on "about 6 January 1548, at a parsonage located a half mile from distant Salisbury."
Mary Neville, who married Sir Thomas Danby of Farnley Hall, Yorkshire, eldest son of Sir Christopher Danby. Sir Thomas Danby appears to have participated with his brothers-in-law, Christopher Neville and Cuthbert Neville, in the Northern Rebellion of 1569.
Margaret Neville (d. 13 October 1559), who married, at a triple Neville-sibling marriage ceremony on 3 July 1536 at Holywell in Shoreditch, as his first wife, Henry Manners, 2nd Earl of Rutland, and had issue.
Elizabeth Neville, who married, as his first wife, Thomas Dacre, 4th Baron Dacre (d. 1 July 1566) of Gilsland, but died without issue. After Elizabeth Neville's death, Thomas Dacre married Elizabeth Leyburne (buried 18 September 1567), who, after Dacre's death, married, as his third wife, Thomas Howard, 4th Duke of Norfolk.
Eleanor Neville, who married, as his first wife, Sir Bryan Stapleton (d. 13 December 1606) of Carlton, Yorkshire, eldest son of Sir Richard Stapleton (c.1516 – 1585), 'one of the carpet knights made at the accession of Queen Mary', and Thomasin Amadas, the daughter of Robert Amadas, goldsmith and master of King Henry VIII's jewel house. After Eleanor Neville's death, Sir Brian Stapleton married Elizabeth Darcy, the daughter of George Darcy, 2nd Baron Darcy de Darcy.
Anne Neville (buried 17 July 1583 at Alcester, Warwickshire), who married, about 1553, Sir Fulke Greville (1536–1606), de jure 4th Baron Willoughby de Broke, and by him had issue a son, Fulke Greville, 1st Baron Brooke, friend of Sir Philip Sidney, and a daughter, Margaret Greville (1561–1631/2), who married Sir Richard Verney.
