Thefeudal barony of Abergavenny came into existence shortly after theNorman Conquest of 1066.[1] The barony by writ was first created in 1392 forSir William de Beauchamp, a younger son of the11th Earl of Warwick. This creation passed to his son, who succeeded as2nd Baron, and who was subsequently createdEarl of Worcester. On his death, the Earldom of Worcester became extinct, but the Barony passed to his daughter, who by modern doctrine succeeded as3rd Baroness. She died in 1447 when the Barony descended to her son, who succeeded as4th Baron.
In 1450,Sir Edward Nevill, widower of the 3rd Baroness, wassummoned toParliament as Lord Bergavenny. It has been assumed that this summons was intended to be in the right of his wife, but as she was already dead and the Barony was already vested in her son by Nevill, by modern doctrine this served to create a new Barony by writ. This second creation merged with the first creation in 1476, when the 1st Baron (of the second creation) died and his son, the aforementioned 4th Baron of the first creation, also became 2nd Baron of the second creation.
In 1587, on the death of the6th Baron (of the first creation) and 4th Baron (of the second creation), by modern doctrine both Baronies descended to his daughter,Mary, Lady Fane, wife ofSir Thomas Fane, who thus becamede jure 7th and 5th Baroness. The title (for it was believed at the time only to be one Barony) was claimed byEdward Nevill, the heir male of the 4th and 2nd Baron, and in 1604 he was summoned to Parliament as Lord Bergavenny. As he was not entitled to either of the existing Baronies, this served to create a further Barony by Writ. By modern doctrine, the first and second creations descended to theEarls of Westmorland, heirs of the 7th and 5th Baroness, until both became abeyant on the death of the 7th Earl (and 14th and 12th Baron) in 1762.
The wrongful assumption that the Barony descended to heirs male continued, and this pattern (heirs general being deprived of their rightful title and heirs male being summoned to Parliament, with a new title being created in the process) was repeated several times, resulting in the fourth to seventh creations. The fourth and fifth creations became extinct on the death of the first holder of each, who both died without heirs, and the sixth becameabeyant in 1811. The provenance of the third creation is unclear. None of these new creations were recognised as such at the time.
The last creation, and the only one in the Peerage of Great Britain, came in 1724, in favour ofWilliam Nevill. His son, who succeeded as2nd Baron, was createdEarl of Abergavenny in 1784, and the5th Earl was createdMarquess of Abergavenny in thePeerage of the United Kingdom in 1876. The Barony descended with the Earldom and then also the Marquessate (both of which were limited to heirs male) until 1938 when the3rd Marquess died leaving no surviving sons but two surviving daughters, whereupon the Barony fell into abeyance between them. By the principle ofmoiety title, the heirs of those daughters – the 6th Marquess Camden and the23rd Baron Hastings – are the co-heirs to one half of the Barony each, and neither has petitioned for the title to be settled upon one or the other (cf.Baron Arlington).
On the death of the 5th Marquess of Abergavenny in 2000, the pretence that the Barony of Bergavenny descended to heirs male was finally dropped, and so the6th Marquess of Abergavenny does not claim to hold it.[citation needed]
