Researching John Younger

A friend of Alexander Pope, Caryll was the son of Richard Caryll (1635–1701), of West Grinstead, Sussex, and Frances née Bedingfield (c.1644–1704), and nephew and heir of John Caryll, Jacobite first Baron Caryll of Durford. He succeeded his uncle in 1711. He married, in 1686, Elizabeth, daughter of John Harrington, of Orle Place, Sussex, by whom he had 10 children, 4 sons (2 of whom married and had issue, while one became a Jesuit priest) and 6 daughters (5 of whom became nuns).

On his death, he was succeeded in the Jacobite title, by his grandson, John Baptist Caryll, the eldest son of his predeceased (in 1718) eldest son, also John, who sold the family properties at West Grinstead and Harting, West Sussex, and entered the household in Rome of the so-called "Young Pretender", the exiled Stuart claimant, recognised by Jacobites as "King Charles III". Charles Edward Stuart appointed Caryll his Secretary of State and made him a Knight of the Thistle. Caryll returned to France in 1777 and died at Dunkirk on 7 March 1788.

Educated at Eton and the Royal Military Academy Sandhurst, Younger was commissioned into the Argyll and Sutherland Highlanders in 1959, and served in Borneo and Singapore before joining the Directorate of Military Operations at the Ministry of Defence in 1967. He retired from the Army in 1969 and was with Scottish and Newcastle Breweries from 1969 to 1979 before becoming one of the founding partners of the Broughton Brewery in 1979.

In 1969 he became a member of the Royal Company of Archers, which is the Queen's Bodyguard for Scotland, and was its Secretary from 1993 to 2007. He was Vice-President of the Royal Highland and Agricultural Society of Scotland in 1994, and became Vice-Lord Lieutenant of Tweeddale in 1992, before becoming Lord Lieutenant in 1994.
