Campbell, John, 4th Duke of Argyll (1693 -1770)
John Campbell was the son of Hon. John Campbell of Mamore (the second son of Archibald Campbell, 9th Earl of Argyll), and Elizabeth Elphinstone, daughter of John, 8th Lord Elphinstone. In 1720 he married Mary Drummond Ker, daughter of John Drummond Ker, 2nd Lord Bellenden of Broughton. The marriage produced three children.
Campbell pursued a military career, rising to the rank of lieutenant general in 1747. In addition, he was a Scottish Whig politician, becoming MP for Buteshire, Elgin Burghs, and Dunbartonshire. In 1761 he inherited the dukedom and other titles upon the death of his cousin Archibald Campbell, 3rd Duke of Argyll. At the same time, he left politics, and became Governor of Limerick. In 1762 he was made a Privy Councillor, and in 1765 he was created a Knight of the Order of the Thistle. He died in 1770, and was succeeded by his son John.
