Francis Jeune, 1st Baron St Helier

Francis Henry Jeune, 1st Baron St Helier GCB PC QC (17 March 1843 – 9 April 1905), known as Sir Francis Jeune (1891–1905), was a British judge. He was President of the Probate, Divorce and Admiralty Division of the High Court of Justice (1892–1905) and Judge Advocate General (1892–1905).

Jeune was the son of The Right Reverend Francis Jeune, Bishop of Peterborough, and Margaret, daughter of Henry Symons. Educated at Harrow and Balliol College, Oxford, he was President of the Oxford Union in 1864. In 1868, he was called to the Bar, Inner Temple.

In 1888, Jeune became a Queen's Counsel. In 1891, he was appointed as a Judge in the Probate, Divorce and Admiralty Division of the High Court and knighted. In June 1892, he became President of the Division in succession to Sir Charles Parker Butt and sworn of the Privy Council. In December of that year, he was also appointed Judge Advocate General by Liberal Prime Minister William Ewart Gladstone. He continued as President of the Probate, Divorce and Admiralty Division until January 1905 when, beset by ill health, he resigned. In 1897, he was appointed a Knight Commander of the Order of the Bath (KCB) and, in 1902, a Knight Grand Cross of the Order of the Bath (GCB). In February 1905, he was granted an annuity of £3,500 and raised to the peerage as Baron St Helier of St Helier in the Island of Jersey and of Arlington Manor in the County of Berkshire.

On 17 August 1881, Lord St Helier married Susan Mary Elizabeth Stanley, the recently widowed daughter of Keith William Stewart-Mackenzie and Hannah Charlotte Hope-Vere. In 1882, their only child, a son, Francis Jeune, was born; on 19 August 1904, he died of enteric fever in Poona, India. Lord St Helier died the next year, on 9 April 1905, aged 62. As he had no surviving male issue, the barony died with him. Lady St Helier died in January 1931.
