Life

John Byrne Leicester Warren, third and last Baron de Tabley, was born at Tabley House, Cheshire on 26 April 1835. He was the eldest son of George Fleming Leicester (afterwards Warren), Lord de Tabley (1811–1887), and his wife (married: 1832) Catherina Barbara (1814–1869), second daughter of Jerome, Count de Salis-Soglio.

The young Warren, as he then was, was educated at Eton from 1847 to 1851, in the Rev. Edward Coleridge's house, and then at Christ Church, Oxford, where he graduated in 1856 with second class honours in classics, law, and modern history. In the autumn of 1858 he went to Turkey as unpaid attaché to Lord Stratford de Redcliffe. In 1860 he was called to the bar from Lincoln's Inn. He was commissioned as a part-time Lieutenant in the Cheshire Yeomanry and unsuccessfully contested Mid-Cheshire as a Liberal in 1868.
