He married twice, firstly on 30 May 1839 to Dorothea Pennefather (1824–1861), daughter of the eminent judge Richard Pennefather and his wife Jane Bennett. He married secondly, on 31 May 1864, to Mary Anne Delap (died 1873), daughter of Samuel Delap of Monellan Castle, near The Cross, just outside Killygordon in the east of County Donegal. Samuel Delap married Jane Bennett's sister Susannah, and thus Lord Farnham's two wives were cousins. On his older brother's death, he succeeded as The 8th Baron Farnham on 20 August 1868. Lord Farnham died on 4 June 1884, without issue, and was succeeded by his younger brother, James.
