Earl Winterton is a title in the Peerage of Ireland. It was created in 1766 for Edward Turnour Garth-Turnour, along with the courtesy title Viscount Turnour. Garth-Turnour, who represented Bramber in the House of Commons, had already been created Baron Winterton, of Gort in the County of Galway, in 1761, also in the Peerage of Ireland. In 1952 the sixth Earl was created Baron Turnour, of Shillinglee in the County of Sussex, in the Peerage of the United Kingdom. However, this title became extinct on his death while he was succeeded in the Irish titles by his distant relative Ronald Chard Turnour, who became the seventh Earl. He was a descendant of the third son of the second Earl, and lived in Canada. On his death in 1991 the titles passed to his nephew, the eighth and present holder. He also lives in Canada.

For instance, the eldest son of the Duke of Buccleuch and Queensberry is the Earl of Dalkeith, even though the Duke is also the Marquess of Dumfriesshire, a senior title to the Earldom of Dalkeith.
For instance, the eldest son of the Earl of Devon is Lord Courtenay, even though the Earl has no barony of that name, and similarly the eldest son of the Earl of Guilford is Lord North.
Thus a baron's wife is called "baroness", an earl's wife is called a "countess", a duke's wife a "duchess", etc. Despite being referred to as a "peeress", she does not, however, become a peer "in her own right": these are 'styles', not substantive titles.
