On 9 May 1833, he had married Lady Mary Augusta Coventry (11 May 1812 – 23 September 1889) (a daughter of the 8th Earl of Coventry); although the marriage produced no children, they did have an adopted daughter, Marie "Mary" Henriette Adelaide Fox (Paris, 21 December 1850 – Schloss Burgstall, Steiermark, 26 December 1878) (who was said to be and most likely was his illegitimate child by an unknown presumably French mother), who married in London on 27 June 1872 Prince Aloys Franz de Paula Maria of Liechtenstein (Vienna, 19 November 1846 – Vienna, 25 March 1920) (later remarried in Vienna on 20 May 1890 without issue to Johanna Elisabeth Maria von Klinkosch (Vienna, 13 August 1849 – Baden bei Wien, 31 January 1925), daughter of Joseph, Ritter von Klinkosch and Elise Swoboda), by whom she had four daughters, the middle two of which died unmarried and the first one married without any issue. As Lord Holland died without male issue, in Naples, his titles became extinct.
