Garret Wesley, 1st Earl of Mornington

Garret Colley Wesley, 1st Earl of Mornington (19 July 1735 – 22 May 1781) was an Anglo-Irish politician and composer, best known today for fathering several distinguished military commanders and politicians of Great Britain and Ireland.

Wesley was born at the family estate of Dangan Castle, near Summerhill, a village near Trim in County Meath, Ireland, to Richard Wesley, 1st Baron Mornington, and Elizabeth Sale. He was educated at Trinity College Dublin, and was elected its first Professor of Music in 1764. From early childhood he showed extraordinary talent on the violin, and soon began composing his own works. As a composer he is remembered chiefly for glees such as "Here in cool grot" (lyrics by William Shenstone) and for a double Anglican chant. It was the future Duke of Wellington who, alone of his children, inherited something of his musical talent.

Wesley represented Trim in the Irish House of Commons from 1757 until 1758, when he succeeded his father as 2nd Baron Mornington. In 1759 he was appointed Custos Rotulorum of Meath and in 1760, in recognition of his musical and philanthropic achievements, he was created Viscount Wellesley, of Dangan Castle in the County of Meath, and Earl of Mornington. He was elected Grandmaster of the Grand Lodge of Ireland in 1776, a post he held until the following year. Like his father he was careless with money, and his early death left the family exposed to financial embarrassment, leading ultimately to the decision to sell all their Irish estates.

Four streets in Camden Town, which formed part of the estate of his son-in-law Henry FitzRoy, were named Mornington Crescent, Place, Street and Terrace after him. Of these, the first has since become famous as the name of a London Underground station.

Wesley married The Hon. Anne Hill-Trevor, eldest daughter of the banker Arthur Hill-Trevor, 1st Viscount Dungannon, and his wife Anne Stafford, on 6 February 1759. His godmother, the famous diarist Mary Delany, said the marriage was happy, despite his lack of financial sense and her "want of judgment". They had nine children, most of them were historically significant:

Four of Lord Mornington's five sons were created peers in the Peerages of Great Britain and the United Kingdom. The Barony of Wellesley (held by the Marquess Wellesley) and the Barony of Maryborough are now extinct, whilst the Dukedom of Wellington and Barony of Cowley are extant. The Earldom of Mornington is held by the Dukes of Wellington, and the Barons Cowley has since been elevated to be Earls Cowley.
