Lancelot Baugh Allen
He was the son of John Bartlett Allen, a local landowner and colliery owner in Cresselly, Pembrokeshire. Allen had one younger brother, John Hensleigh Allen, MP for Pembrokeshire, and nine sisters whose husbands included Josiah Wedgwood II of the Wedgwood pottery firm, Sir James Mackintosh (MP), John Wedgwood the horticulturist and Jean Charles Léonard de Sismondi, the historian.
Allen studied at Westminster School and Trinity College, Cambridge where he was elected a scholar "but not admitted, in consequence of his refusal to take the statutable oath." He was later admitted at Lincoln's Inn however, on 9 May 1798, called to the Bar in 1803 and later admitted at the Inner Temple, London on 21 June 1819.
Two marriages gave Allen five children. In 1820 he married Caroline Jane Romilly who gave him two sons, George Baugh Allen and Edmund Edward Allen. His second marriage to Georgina Sarah Bayly in 1841 produced two sons and a daughter: Charles Hensleigh Allen, Clement Francis Romilly Allen, and Elizabeth Jessie Jane Allen (1845-1918).
