In 1869 he was sworn of the Privy Council,[7] but never returned to active political office, although he accepted appointment as Lord-Lieutenant of Nottinghamshire serving between 1880[8] and 1898.[9]

St Albans married twice, first to Sybil Mary Grey (28 November 1848 – 7 September 1871, London), daughter of Lt.-Gen. Sir Charles Grey and granddaughter of Charles, 2nd Earl Grey, on 20 June 1867 in London. They had three children:[3]

She was the granddaughter of London Sephardic Jewish Shakespearian actor turned parliamentarian Ralph Bernal. Her father Ralph Bernal Jr., later Ralph Bernal Osborne, was Secretary of the Admiralty and a parliamentarian. Grace's mother was an Osborne, an Anglo-Irish landed family;

The Duke's second marriage produced five children:
