Sir Lancelot Charles Lee Brenton, 2nd Baronet (16 February 1807 – 13 June 1862) was the translator of one of only two English translations of the Septuagint.
Lancelot Brenton was the second of four children of Sir Jahleel Brenton, 1st Baronet, a Vice Admiral in the British Royal Navy who was made a baronet for services to the crown. It was this title that Lancelot Brenton inherited (his older brother John Jervis Brenton having died in 1817). Lancelot however didn't inherit his father's acceptance of war; when he re-edited his father's biography he made it clear that he was a pacifist.
He trained for the ministry at Oriel College, Oxford, and was ordained by the Church of England in 1830. By December 1831 he had left the Established Church to found an independent chapel in Bath with a friend, William Moreshead. He had met John Nelson Darby at Oxford in 1830. By 1835 this chapel was associated with the Plymouth Brethren and by 1837 Brenton was contributing to The Christian Witness, an early Brethren journal, and appears to have cemented his relationship with the emerging Brethren movement.
On the death of his father in 1844, Brenton became Sir Charles. He moved to the Isle of Wight from Bath in 1849 where, although married, he died childless, the second and last Baronet of his line.
Brenton's translation of the Septuagint was the second English translation available. It was first released in 1844 and has gone through several reprints and formats in the over a century and a half since.
