The title of Duke of Ireland was created in 1386 for Robert de Vere , 9th Earl of Oxford ( 1362-1392 ) , the favourite of King Richard II of England , who had previously been created Marquess of Dublin . Both were peerages for one life only . At this time , only the Pale of Ireland ( the Lordship of Ireland ) was under English control . Despite its name , the Dukedom of Ireland is generally considered to have been one in the Peerage of England , and is the first time that a Ducal title was created for someone who was not a close relative of the King .

The title Marquess of Dorset has been created three times in the Peerage of England . It was first created in 1397 for John Beaufort , 1st Earl of Somerset , but he lost the title two years later . It was then created in 1442 for Edmund Beaufort , 1st Earl of Dorset , who was created Duke of Somerset in 1448 . That creation was attainted in 1463 . It was created a third time in 1475 for Thomas Grey , 1st Earl of Huntingdon , who then resigned the earldom . The Marquess held the subsidiary title of Baron Ferrers of Groby ( 1300 ) . The third marquess was created Duke of Suffolk in 1551 , but he was attainted in 1554 and all the peerages were forfeited .
Duke of Somerset , from the county of Somerset , is a title that has been created five times in the peerage of England . It is particularly associated with two families : the Beauforts , who held the title from the creation of 1448 , and the Seymours , from the creation of 1547 , in whose name the title is still held . The present dukedom is unique , in that the first holder of the title created it for himself in his capacity of Lord Protector of the Kingdom of England , using a power granted in the will of his nephew King Edward VI . The only subsidiary title of the duke of Somerset is Baron Seymour , which is used as a courtesy title by the eldest son and heir of the duke . This courtesy title is the lowest in rank of all heirs to dukedoms in the peerages of the British Isles , yet the holder 's precedence is higher than his title suggests , by virtue of the seniority of the Dukedom of Somerset ( the only more senior non-royal duke is the Duke of Norfolk ) . Several other titles have been held by the dukes of Somerset , but have become extinct . These include : Earl of Kendal ( created 1443 , extinct 1444 ) , Earl of Somerset ( created 1397 , forfeit 1461 ) , Marquess of Dorset ( created 1397 , degraded 1399 ; created 1442 , forfeit 1461 ) , Marquess of Somerset ( created 1397 , degraded 1399 ) , Earl of Dorset ( created 1441 , forfeit 1461 ) , Viscount Rochester ( created 1611 , extinct 1645 ) , Viscount Beauchamp of Hache ( created 1536 , forfeit 1552 ) , Earl of Hertford ( created 1537 , forfeit 1552 ; and created 1559 , extinct 1750 ) , Marquess of Hertford ( created 1640 , extinct 1675 ) , Baron Seymour of Trowbridge ( created 1641 , extinct 1750 ) , Baron Percy ( created 1722 , separated 1750 ) , Baron Cockermouth ( created 1749 , separated 1750 ) , Earl of Egremont ( created 1749 , separated 1750 ) , and Earl St. Maur ( created 1863 , extinct 1885 ) . The ducal seat is Bradley House in Maiden Bradley , west Wiltshire , with a secondary estate at Berry Pomeroy Castle , Totnes , Devon . The principal burial place for the Seymour family today is All Saints ' Church , Maiden Bradley , adjacent to Bradley House ; the church and the family cemetery can be reached from the grounds of Bradley House via private access .

Duke of Suffolk is a title that has been created three times in the peerage of England . The dukedom was first created for William de la Pole , who had already been elevated to the ranks of earl and marquess , and was a powerful figure under Henry VI . The second creation was for Charles Brandon , a favourite of Henry VIII ; his son and two grandsons successively inherited the title , but left no more heirs . The third creation of the dukedom of Suffolk was for Henry Grey , 3rd Marquess of Dorset , in 1551 . The duke also held the title Baron Ferrers of Groby ( 1300 ) . These titles became forfeit when the duke was attainted in 1554 .
The title of Marquess of Montagu was created in 1470 for John Neville , 1st Earl of Northumberland , younger brother of Warwick the Kingmaker . Montagu was killed at the Battle of Barnet in 1471 , and was attainted and the peerage forfeit .

He was buried at St. Augustine 's Friars , London according to one source , but most likely in the Berkeley family foundation of St Augustine 's Abbey , Bristol .
Marquess of Exeter is a title that has been created twice , once in the Peerage of England and once in the Peerage of the United Kingdom . The first creation came in the Peerage of England in 1525 for Henry Courtenay , 2nd Earl of Devon . For more information on this creation , which was forfeited in 1538 , see the Earl of Devon .
Marquess of Pembroke was a title in the Peerage of England created by King Henry VIII for his future spouse Anne Boleyn . It was the first hereditary peerage granted to a woman .
Anne Boleyn ( /ˈbʊlɪn , bʊˈlɪn/ ; c. 1501 - 19 May 1536 ) was Queen of England from 1533 to 1536 as the second wife of King Henry VIII . Their marriage , and her execution for treason and other charges by beheading , made her a key figure in the political and religious upheaval that marked the start of the English Reformation . Anne was the daughter of Thomas Boleyn , 1st Earl of Wiltshire , and his wife , Lady Elizabeth Howard , and was educated in the Netherlands and France , largely as a maid of honour to Queen Claude of France . Anne returned to England in early 1522 , to marry her Irish cousin James Butler , 9th Earl of Ormond ; the marriage plans were broken off , and instead she secured a post at court as maid of honour to Henry VIII 's wife , Catherine of Aragon . Early in 1523 Anne was secretly betrothed to Henry Percy , son of Henry Percy , 5th Earl of Northumberland , but the betrothal was broken off when the Earl refused to support their engagement . Cardinal Thomas Wolsey refused the match in January 1524 and Anne was sent back home to Hever Castle . In February or March 1526 , Henry VIII began his pursuit of Anne . She resisted his attempts to seduce her , refusing to become his mistress , which her sister Mary had been . Henry soon focused his desires on annulling his marriage to Catherine so he would be free to marry Anne . When it became clear that Pope Clement VII would not annul the marriage , Henry and his advisers began the breaking of the Catholic Church 's power in England . In 1532 , Henry granted Anne the Marquessate of Pembroke . Henry and Anne formally married on 25 January 1533 , after a secret wedding on 14 November 1532 .
Marquess of Northampton is a title that has been created twice , firstly in the Peerage of England ( 1547 ) , then secondly in the Peerage of the United Kingdom ( 1812 ) . The current holder of this title is Spencer Compton , 7th Marquess of Northampton .
Marquess of Winchester is a title in the Peerage of England that was created in 1551 for the prominent statesman William Paulet , 1st Earl of Wiltshire . The Marquessate is the only English one in existence ( extant ) therefore its holder is considered the Premier Marquess of England . The current holder is Nigel Paulet , 18th Marquess of Winchester ( born 1941 ) whose son uses the courtesy title Lord Wiltshire .

Marquess of Buckingham may refer to :
Duke of Buckingham , referring to Buckingham , is a title that has been created several times in the peerages of England , Great Britain , and the United Kingdom . There have also been Earls of Buckingham and Marquesses of Buckingham .
The titles of Earl of Hertford and Marquess of Hertford have been created several times in the peerages of England and Great Britain . The third Earldom of Hertford was created in 1559 for Edward Seymour , who was simultaneously created Baron Beauchamp of Hache . His grandson William Seymour was subsequently created Marquess of Hertford and restored to the title of Duke of Somerset ; the Marquessate became extinct in 1675 and the other three titles in 1750 . The present Marquessate was created in 1793 . Lord Hertford holds the subsidiary titles of Earl of Yarmouth ( Peerage of Great Britain , 1793 ) , Earl of Hertford ( Peerage of Great Britain , 1750 ) , Viscount Beauchamp ( Peerage of Great Britain , 1750 ) , Baron Conway , of Ragley in the County of Warwick ( Peerage of England , 1703 ) , and Baron Conway of Killultagh , of Killultagh in the County of Antrim ( Peerage of Ireland , 1712 ) . Lord Hertford 's heir uses the style Earl of Yarmouth . The Marquesses of Hertford are members of the Seymour family headed by the Duke of Somerset . Francis Seymour ( 1679-1732 ) was the fourth son of Sir Edward Seymour of Berry Pomeroy , 4th Baronet , a descendant of Edward Seymour , 1st Duke of Somerset ( Sir Edward 's grandson Sir Edward Seymour , 6th Baronet , of Berry Pomeroy succeeded as 8th Duke of Somerset in 1750 ) . Upon the death of his elder brother , Francis succeeded to the estates of his relative Edward Conway , 1st Earl of Conway . In 1703 he was created Baron Conway in the Peerage of England and assumed the additional surname of Conway . In 1712 he was created Baron Conway of Killultagh in the Peerage of Ireland . In 1750 his son Francis Seymour-Conway , 2nd Baron Conway , was created Viscount Beauchamp and Earl of Hertford .
Duke of Beaufort , a title in the Peerage of England , was created by Charles II in 1682 for Henry Somerset , 3rd Marquess of Worcester , a descendant of Charles Somerset , 1st Earl of Worcester , legitimized son of Henry Beaufort , 3rd Duke of Somerset , a Lancastrian leader in the Wars of the Roses . The name Beaufort refers to a castle in Champagne , France ( now Montmorency-Beaufort ) . It is the only current dukedom to take its name from a place outside the British Isles . [ citation needed ] The Dukes of Beaufort descend in the male line from the House of Plantagenet through John of Gaunt , son of Edward III . This statement was challenged after the analysis of the Y chromosomal DNA of the remains of Richard III . Most living male heirs of the 5th Duke of Beaufort were found to carry a relatively common Y chromosome type , which is different from the rare lineage found in Richard III 's remains . The instance of false paternity could have occurred anywhere in the numerous generations separating Richard III from the 5th Duke of Beaufort . The break also could have occurred with Richard III 's grandfather Richard of Conisburgh , whose paternity has been called into question although he was acknowledged by his father . The Beaufort Castle was in possession of John of Gaunt , and the surname Beaufort was given to Gaunt 's four legitimised children by his mistress and third wife , Katherine Swynford . This was the foundation of the House of Beaufort , Dukes of Somerset . A descendant of the Beauforts through his mother was Henry VII of England . Charles Somerset , 1st Earl of Worcester , KG ( c. 1460 - 15 March 1526 ) , was the bastard son of Henry Beaufort , 3rd Duke of Somerset by his mistress Joan Hill .

Duke of Newcastle upon Tyne is a title that has been created three times . The related title Duke of Newcastle-under-Lyne [ sic ] has been created once to provide a slightly more remote special remainder . The title first was conferred in 1665 when William Cavendish was made Duke of Newcastle upon Tyne . He was a prominent Royalist commander in the Civil War . He had already been elevated as Viscount Mansfield in 1620 , Baron Cavendish of Bolsover and Earl of Newcastle upon Tyne in 1621 and Marquess of the latter in 1643 , and was created Earl of Ogle as main subsidiary title to the dukedom to be used as a courtesy style for his heir presumptive . The titles became extinct in 1988 , a year that saw the deaths of the distantly related ninth and tenth Dukes of Newcastle-under-Lyne . Despite the name of the town being Newcastle-under-Lyme with an m , the dukedom was created with Lyne with an n. There is no known satisfactory explanation for the discrepancy , which may have been an error . However , if it was an error , that error has perpetuated itself in numerous sources , including peerage catalogues .

Duke of Kingston-upon-Hull was a title in the Peerage of Great Britain , with the title Earl of Kingston-upon-Hull being a title in the Peerage of England . The Earldom was created on 25 July 1628 for Robert Pierrepont , 1st Viscount Newark . The Dukedom was created on 10 August 1715 for his great-grandson , Evelyn Pierrepont , 1st Marquess of Dorchester , who had succeeded as the fifth Earl of Kingston-upon-Hull in 1690 . The Dukedom became extinct on the death of the second Duke in 1773 . Unlike the city to which they refer , Kingston upon Hull , which is usually shortened to Hull , these titles are usually shortened to Duke ( or Earl ) of Kingston . ( The titles were hyphenated but the city is now usually written without hyphens . ) They should not be confused with the separate Irish Earldom of Kingston ( which refers to the town of Kingston in County Dublin ) .
The title Marquess of Halifax was created in the Peerage of England in 1682 for the 1st Marquess of Halifax . The 1st Marquess , George Savile , had previously been created Baron Savile , of Elland in the County of York , and Viscount Halifax in 1668 and Earl of Halifax in 1679 , all also in the Peerage of England . The Baronetcy , styled of Thornhill in the County of York , had been created in the Baronetage of England in 1611 for his great-grandfather George Savile . All the peerages became extinct on the death of the 2nd Marquess in 1700 . The Baronetcy was inherited by a kinsman , the 6th Baronet , and became extinct on the death of the 8th Baronet in 1784 . The courtesy title used by the heir apparent to the Earldom and Marquessate was Lord Elland , taken from the territorial designation of the Barony of Savile . The family seat was originally Thornhill Hall , which was destroyed in the English Civil War , after which the seat was transferred to Rufford Abbey .
Marquess of Powis was a title in the Peerage of England . It was created in 1687 for William Herbert , 1st Earl of Powis . He had already succeeded his father as third Baron Powis in 1667 and had been created Earl of Powis in the Peerage of England in 1674 ; Marquess of Powis and Viscount Montgomery in 1687 . When James II went into exile in France , the Marquess followed him . He served as Comptroller of the Royal Household and his wife Elizabeth as Governess of the Royal children . He was rewarded in 1698 by the titles Duke of Powis and Marquess of Montgomery , but these titles in the Jacobite Peerage ( though used ) were not recognised in England . The title of Baron Powis was created in the Peerage of England in 1629 for William Herbert . He was the son of Sir Edward Herbert , second son of William Herbert , 1st Earl of Pembroke and Anne Parr . This Herbert family were thus members of a junior branch of the prominent Welsh family headed by the Earl of Pembroke . The peerages became extinct on the death of the first Marquess 's grandson , the third Marquess , in 1748 . Barbara , daughter of Lord Edward Herbert , younger son of the second Marquess of Powis and brother of the third Marquess , married Henry Arthur Herbert , who was created Earl of Powis in 1748 . They inherited his estates .
Duke of Leeds was a title in the Peerage of England . It was created in 1694 for the prominent statesman Thomas Osborne , 1st Marquess of Carmarthen . He had already succeeded as 2nd Baronet , of Kiveton ( 1647 ) and been created Viscount Osborne , of Dunblane ( 1673 ) , Baron Osborne , of Kiveton in the County of York ( also 1673 ) and Viscount Latimer , of Danby in the County of York ( also 1673 ) , Earl of Danby , in the County of York ( 1674 ) , and Marquess of Carmarthen ( 1689 ) . All these titles were in the Peerage of England , except for the viscountcy of Osborne , which was in the Peerage of Scotland . [ note 1 ] He resigned the latter title in favour of his son in 1673 . The Earldom of Danby was a revival of the title held by his great-uncle , Henry Danvers , 1st Earl of Danby ( see Earl of Danby ) . The Dukedom was named for Leeds in Yorkshire , and did not ( as is sometimes claimed ) refer to Leeds Castle in Kent . The principal ducal seat was Kiveton Hall . After Kiveton Hall was demolished in 1811 , Hornby Castle became the main seat of the Dukes of Leeds . The traditional burial place of the Dukes of Leeds was All Hallows Church , Harthill , South Yorkshire . The 4th Duke married Mary Godolphin , daughter of Henrietta Churchill Godolphin , su jure Duchess of Marlborough , and The 2nd Earl of Godolphin , and assumed the arms of Godolphin and Churchill . On 8 August 1849 , The 7th Duke of Leeds assumed by royal licence the additional surname and arms of D'Arcy , for the Barony of D'Arcy ( 1322 ) and Conyers he inherited through his grandmother .
