On 2 June 1842 he married Elizabeth Sarah Cathcart, youngest daughter of the Hon. and Rev. Archibald Hamilton Cathcart and Frances Henrietta Fremantle and granddaughter of Charles Cathcart, 9th Lord Cathcart.[1] They had no children.
Two of his nephews, William Horwood Stuart and Charles Leader Justice Stuart, the sons of his brother the Rev. William Stuart (Vicar of Mundon and Rector of HazeleighinEssex), also entered the diplomatic service and served around the Black Sea, although both also had their careers cut short: Charles drowned in the DanubeatBrăilainRomania in 1885 and William was murdered at BatuminGeorgia in 1906. Another nephew, the Rev. Robert Stuart King, was a clergyman and football player.
Stuart purchased an ensign in the 44th Foot in 1834. Later promoted lieutenant, he exchanged into the 7th Foot in 1838 and purchased a captaincy in 1842. He exchanged into the 41st Foot in 1851 and retired in 1852.
During the Crimean War, however, he rejoined the army, rising to the rank of major and serving on the staff of General Fenwick Williams.[3] He remained in the region after the war. In 1858 he was appointed Vice-Consul at Volos, and in 1860 was sent to investigate the condition of Christians in Thessaly and Epirus. In 1861 he became Consul in Albania, based in Janina.[4] In 1873 he was made Consul-General for the Russian ports in the Black Sea and the Sea of Azof, and was based at Odessa – at this time his private secretary was his nephew, William Horwood Stuart.
In 1874 he became Consul-General in Haiti and Chargé d'Affaires for the Dominican Republic, and in 1876 he helped to save the life of the President of Haiti, Michel Domingue, during an uprising. He was also the author of a confidential report sent to the Foreign Office entitled "The People of the Haitian Republic", which may have been an unacknowledged source for the memoirs of his predecessor, Spenser St. John, which were published in 1884.[5]
Stuart retired in 1883 to Breton Lodge, Leamington Spa, where he died on 17 June 1901 at the age of 88; he is buried in Leamington Cemetery.[1]
In 1856, Stuart led an expedition to the summit of Mount Ararat, along with Major Alick Fraser, the Rev. Walter Thursby, James Theobald and John Evans.[6]
