The title Earl of Glasgow was bestowed on David Boyle, Lord Boyle, one of the commissioners who negotiated the Treaty of Union uniting England and Scotland into Great Britain.
The titles held by the Earl are: Viscount of Kelburn (created 1703), Lord Boyle of Kelburn, Stewartoun, Cumbrae, Finnick, Largs and Dalry (1699), Lord Boyle of Stewartoun, Cumbraes, Fenwick, Largs and Dalry (1703) and Baron Fairlie (1897). The earldom and all subsidiary titles are in the Peerage of Scotland, except that the barony of Fairlie is in the Peerage of the United Kingdom.
In 1869, the 6th Earl of Glasgow inherited Kelburn and land in Dalry, Stewarton, Corshill and Fenwick and the estate at Hawkeshead outside Paisley, plus estates in Dunbartonshire, Fife, Northumberland and the greater part of Cumbrae.
Within the wooded area of the grounds is a monument (on the right) to one of the Earls of Glasgow, erected in 1775, by his disconsolate widow "to animate his children to his estimable qualities".
The Earl of Glasgow has tackled this with enthusiasm and has created a pet's corner, a wooden stockade, a woodland adventure trail, a marine assault course as well as a network of woodland nature trails and a beautiful walled garden (the illustration below is from a long hedge made up entirely of camelias).
Then, in 1703, Lord Boyle was advanced in the Peerage of Scotland as Earl of Glasgow, Viscount Kelburn, and Lord Boyle of Stewartoun, andc.
George, 4th Earl of Glasgow, was was created Baron Ross in the Peerage of the United Kingdom in 1815.
David William Maurice Boyle, 9th Earl of Glasgow, served in World War II and was present at both Dunkirk and at the sinking of the German Battleship Bismark.
