Sackville Lane-Fox, 12th Baron Conyers
Lane-Fox was the eldest son of Sackville Lane-Fox and his wife, Lady Charlotte, only daughter of the 6th Duke of Leeds. On 7 August 1846, he became a cornet by purchase in the Royal Horse Guards and exchanged to the 13th Light Dragoons on 28 December 1849. He retired from the regiment in April 1850. He returned to the Army after the outbreak of the Crimean War. On 29 December 1854, he was commissioned an ensign in the 21st Regiment of Foot. Lane-Fox served with the regiment at the Siege of Sevastopol, for which he later received the medal and clasp. He exchanged as a lieutenant into the 87th Regiment of Foot on 22 July 1856 and retired from the regiment around June 1859. He was appointed a cornet in the Yorkshire Hussars on 24 May 1861, but retired from the regiment in September and became a lieutenant in the Royal East Kent Yeomanry on 19 May 1863.
In 1859, Lane-Fox had inherited the Portuguese countship of Mértola and the baronies of Darcy de Knayth and Conyers from his maternal uncle, the 7th Duke of Leeds. On 14 August 1860, Lord Conyers married Mary Curteis and they later had three children:
- The Hon. Sackville FitzRoy Henry (1861–1879)
- The Hon. Marcia Amelia Mary (1863–1926), married Charles Pelham, 4th Earl of Yarborough.
- The Hon. Violet Ida Evelyn (1865–1929), married George Herbert, 4th Earl of Powis.
On Lord Conyers' death in 1888, both baronies became abeyant between his two daughters (as his only son had predeceased him), although his countship passed to his eldest daughter, Marcia. The barony of Conyers was later granted to Marcia in 1892, and the barony of Darcy de Knayth granted to his other daughter, Violet in 1903.
