Lord Frederick William Charles Nicholas Wentworth Hervey () (26 November 1961 – 26 January 1998) was a British aristocrat and political activist. He was the second son of Victor Hervey, 6th Marquess of Bristol, but the only child by his second wife, the heiress Lady Juliet Wentworth-Fitzwilliam. As his elder half-brother was unmarried he was heir presumptive to the Marquessate. At Yale University, he founded the Rockingham Club, a society for aristocracy and royalty. He died in 1998. Origins Lord Nicholas's father was Victor Hervey, 6th Marquess of Bristol (1915–1985) of Ickworth House in Suffolk, a very wealthy aristocrat once described as "Mayfair's No. 1 Playboy," in a series of "life story" articles he wrote after serving a jail sentence for jewel robbery, a crime he claimed he had committed for a dare. Lord Nicholas's mother, his father's second wife whom he had married in 1960 being her first husband, was Lady Juliet Wentworth-Fitzwilliam, the only child and sole heiress of the very wealthy Peter Wentworth-Fitzwilliam, 8th Earl Fitzwilliam (d.1948) who died in a small aircraft crash when she was aged 13. Also killed was his intended second wife, Kathleen Cavendish, Marchioness of Hartington, a daughter-in-law of the Duke of Devonshire and a sister of US President John F. Kennedy. Lady Juliet thus inherited her father's estate of estimated value £45 million, and later managed the family stud farm. After his father's death in 1985 Lord Nicholas was thus the heir presumptive to the title and any entailed estates of the Marquess of Bristol after his unmarried and childless elder half-brother John Hervey, 7th Marquess of Bristol (1954–1999), who inherited in 1985, the only child of his father's first marriage. Nicholas and John were fond of one another. Nicholas was also the heir presumptive of the vast Fitzwilliam inheritance, through his mother. When Nicholas was eleven years old, his mother divorced his father and remarried to his 60-year-old friend, Somerset de Chair (d. 1996) by whom five years later she had a daughter, Helena de chair, who in 2007 married Jacob Rees-Mogg. In 1996 his mother remarried for a third time and is now known as Lady Juliet Tadgell. Nicholas's father also remarried, to his private secretary, Yvonne Sutton by whom he had three further children, Frederick Hervey, 8th Marquess of Bristol (born 1979), who inherited in 1999 and at whose Roman Catholic christening Nicholas had been a godfather, and
