Steuart Denham’s father, an Opposition Whig closely connected with the Duke of Hamilton, dismayed his friends when, in 1745, influenced by his brother-in-law Lord Elcho, he attended Prince Charles Edward Stuart at Holyrood. However, he soon repented and retired to France, where his wife later joined him, leaving their infant son in the care of the family of William Mure of Caldwell. Although not attainted, Sir James was excepted from the Act of Indemnity, and despite the efforts of his relations was obliged to remain in exile.
Young James and his parents lived at Angoulême until, on the eve of war with France, they removed to Flanders, and eventually settled at Tübingen for the boy’s education. Here Sir James by his high character, scholarship, and reputation as an economist, attracted many British visitors and sympathisers, among them Lord Barrington, who in 1761 obtained for young James a commission in General Conway’s regiment. The young man served in Germany from 1762 until the peace, when his father, who had been imprisoned by the French as a British spy, was at last allowed to return home, although not formally pardoned.
As a half pay officer James travelled in France and Germany from 1764 to 1766, studying cavalry tactics and organization,
After his father’s death in 1780 Steuart Denham retained the warm friendship of the Hamilton family, who in 1784 brought him into Parliament for Lanarkshire. Although from Steuart Denham’s connexion with his cousins Henry and Thomas Erskine and Francis Charteris, William Adam counted him ‘doubtful’, he was in effect pledged through Hamilton to support Government.
He died 5 Aug. 1839.
