William Parr , 1st Baron Parr of Kendal William Parr , 1st Baron Parr of Kendal , KG ( 1434 – 1483 ) was an English courtier and soldier . He was the eldest son of Sir Thomas Parr ( 1405 – 1461 ) and his wife Alice ( who was the daughter of Sir Thomas Tunstall of Thurland , Lancashire ) . Family . The Parr family originally came from Parr , Lancashire . Sir William ' s great - grandfather , Sir William de Parre ( died 1405 ) , son of Sir John de Parre , lord of Parr ; married in 1383 Elizabeth de Ros , daughter of Sir John de Ros of Kendal and Katherine de Latimer , a daughter of Thomas , 1st Baron Latimer of Brayebrooke . Elizabeth was the granddaughter and heiress of Sir Thomas de Ros , Baron of Kendal and had livery of her inheritance . Their marriage alliance with the Ros ( or Roos ) family enhanced the Parr family standing . On the accession of the Duke of Lancaster as Henry IV of England , Sir William stood so high in the estimation of the new monarch that he was deputed with the bishop of St . Asaph to announce the revolution to the court of Spain . Through his marriage William acquired , by right of his wife , a fourth part of the manor of Kirby in Kendal , Kendal Castle , and one - fourth part of the barony of Kendal , which continued in the family till after the death of William Parr , Marquis of Northampton , when the Marquis ' s widow surrendered it to Queen Elizabeth I . It was known as ' The Marquis Fee . ' This branch of the family originally resided at Kendal until the Castle fell into disrepair during his son , Thomas ' , life . His paternal grandparents were John Parr ( c . 1383 – 1409 ) and Agness Crophull , widow of Walter Devereux . From her previous marriage she was mother to a younger Walter Devereux and paternal grandmother to Walter Devereux , Lord Chancellor of Ireland . Sir Thomas Parr , the courtier ' s father , was " sub - vice comes " ( i . e . deputy to the hereditary sheriff , Baron Clifford ) for Westmorland from 1428 to 1437 and MP six times . He was assaulted in going to Parliament in 1446 , the case being discussed in Parliament . He took an active part in the Wars of the Roses on the Yorkist side and was subsequently attainted in 1459 with the other leading Yorkists ( iborn v . 348 - 50 ) . The attainder was reversed in 1461 , before his estates had been confiscated . He died in 1464 . Sir Thomas left three sons ( including William , the subject of this article ) and six daughters . Of his other two sons , his second son , Sir John Parr , also a Yorkist , was rewarded by being made sheriff of Westmorland for life in 1462 ; he married a daughter of Sir John Yonge , Lord Mayor of the City of London , and must have lived until after 1473 , as in that year he was one of those exempted from the resumption act ( iborn vi . 81 ) . His third son , Thomas , was killed at the Battle of Barnet in 1471 . His daughters all married members of prominent northern families . Life . William was exempted from the Resumption Act of 1464 . He was on the side of the Nevilles at Banbury in 1469 , was sent by George Plantagenet , 1st Duke of Clarence and Richard Neville , 16th Earl of Warwick to Edward in March 1470 , just before the Battle of Lose - coat Field , and was entrusted by Edward with his answer . When Edward IV returned from exile in 1471 Parr met him at Nottingham , and was rewarded with the comptrollership of the household , which he held until 1475 . He swore to recognise Edward , Prince of Wales , as heir to the throne in 1472 ( iborn vi . 234 ) , and was exempted from the Resumption Act of 1473 ( iborn vi . 81 ) . Parr sat as knight of the shire for UK Parliament constituency in 1467 and 1473 , was High Sheriff of Cumberland for 1473 and invested Knight of the Garter in 1474 . He was sent to the Kingdom of Scotland to arrange about the breaches of the truce probably in 1479 . He was exempted from the act of apparel in 1482 , was chief commissioner for exercising the office of constable of England in 1483 , and took part in the funeral of Edward IV . It seems probable that he died about this time ( cf . Beltz , Memorials of the Garter , pp . 210 , lxxii , clxvii ) , and that the William Parr present at the meeting of Henry VII of England and Philip I of Castile at Windsor , in 1506 , was his second son . Wives and children . Sir William married , first , Joan Trusbut ( died 1473 ) , widow of Thomas Colt of Roydon , Essex ; her issue , if any , did not survive Parr . Joan ' s granddaughter by Colt , Jane , would become the first wife of Sir Thomas More . Secondly , Hon . Elizabeth FitzHugh , daughter of Henry , 5th Baron FitzHugh and Lady Alice Neville , who survived him and remarried Sir Nicholas Vaux ; by her Parr left a daughter Anne , who married Sir Thomas Cheney of Irthlingborough , Northamptonshire , and three sons : Sir Thomas Parr , Sir William Parr , 1st Baron Parr of Horton , and John Parr , Esq . The eldest son , Sir Thomas Parr , was knighted and was sheriff of Northamptonshire in 1509 ; he was master of the wards and comptroller to Henry VIII . He was rich , owing to his succeeding , in 1512 , to half the estates of his cousin , Lord FitzHugh , and also to his marriage with Maud Green , daughter and co - heiress of Sir Thomas Green of Boughton and Greens Norton in Northamptonshire . He died on 12 November 1518 , and was buried in Blackfriars Church , London . His widow died on 1 September 1532 , and was buried beside him . Of their children , Catherine Parr , queen of Henry VIII , and William Parr ( afterwards Marquess of Northampton ) , are separately noticed ; while a daughter , Anne , married William Herbert , first Earl of Pembroke of the tenth creation . The second son of Sir William Parr was William , who was knighted on 25 December 1513 , was sheriff of Northamptonshire in 1518 and 1522 , and after his niece ' s Catherine Parr ' s promotion became her chamberlain . On 23 December 1543 he was created Baron Parr of Horton , Northamptonshire . He died on 10 September 1547 , and was buried at Horton ( for his tomb , see Bridges , " Northamptonshire " , i . 370 ) . By Mary , daughter of Sir William Salisbury , he left four daughters . His daughter Maud and her husband , Sir Ralph Lane , are ancestors of Albert II of Monaco . The late Princess of Wales , Lady Diana Spencer , was also a descendant of Maud " and " Mary Parr . A third son of Sir William Parr , named John , married Constance , daughter of Sir Henry Vere of Addington , Surrey . They had no issue .
