 On 6 May 1724 he entered into a Fleet Marriage with Katherine Tatton, daughter of Lieutenant-General William Tatton and his wife Elizabeth Bull, sister of Sir John Bull, but he died later that year without children.The barony passed to his cousin William Nevill, 16th Baron Bergavenny, who married his widow.As his elder sister Jane (d. 1786) was still alive, this implies that in 1724 at least the barony passed by heirs male not by heirs general.
