Arbuthnot was first married on 28 February 1799 to
Marcia Mary Anne Clapcott Lisle, at Cholmondeley House,
Piccadilly. She had been
Lady-in-Waiting since 1795 to
Caroline of Brunswick, Princess of Wales. She died in
Constantinople on 24 May 1806. Arbuthnot married a second time on 31 January 1814 at
Fulbeck, Lincolnshire, to
Harriet Fane (1793–1834), daughter of the Hon.
Henry Fane. Harriet was fascinated by politics. During her marriage to Arbuthnot, she became a hostess at society dinners given by Arbuthnot's good friend, the Duke of Wellington. Smith rejects the suggestion that Harriet was Wellington's mistress. Her diaries were published as
The Journal of Mrs Arbuthnot in 1950. With his first wife Marcia, Arbuthnot's children were: •
Charles George James Arbuthnot (1799–1870). He married Charlotte Eliza Vivian, daughter of
Hussey Vivian, 1st Baron Vivian. • Caroline Emma Arbuthnot (1802–1852) • Henry Arbuthnot (1803–1875), married in 1830 Charlotte Rachael Scott, daughter of
Thomas Scott, 2nd Earl of Clonmell. • Marcia Emma Georgiana Arbuthnot (1804–1878), who married
William Cholmondeley, 3rd Marquess of Cholmondeley. Arbuthnot had an illegitimate son, from the days before he first married, mentioned in correspondence with his clerical friend John Sneyd (1763–1835), brother of
Walter Sneyd. These letters discuss also his nickname "Gosh", which spread from his familiar circle to being generally used, and mistaken for his surname; and his interest in John de Mainauduc, Irish-Huguenot practitioner of
animal magnetism. Of
Arthur Paget, Arbuthnot's replacement in 1807 at Constantinople, George Canning as incoming
Secretary of State for Foreign Affairs in the
second Portland administration wrote "I must send him to repair if possible the mischief poor Gosh has been doing there." (1793–1834), second wife of Charles Arbuthnot, portrait by
