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

He was born at the family estate of Dangan, 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. 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.

Wesley represented Trim in the Irish House of Commons from 1757 until 1758, when he succeeded his father as 2nd Baron Mornington. 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. Family

He married The Hon. Anne Hill-Trevor, eldest daughter of the banker Arthur Hill-Trevor, 1st Viscount Dungannon, and wife, Anne Stafford, on the 6th of February 1759.[1]
They had six children:

  1. Richard, Viscount Wellesley (20 June 1760 – 26 September 1842); later 1st Marquess Wellesley, 2nd Earl of Mornington.
  2. The Hon. William Wellesley (20 May 1763 – 22 February 1845); later William Wellesley-Pole, 3rd Earl of Mornington, 1st Baron Maryborough.
  3. The Hon. Arthur Wellesley (c. 1 May 1769 – 14 September 1852); later 1st Duke of Wellington.
  4. The Revd and Hon. Gerald Valerian (7 December 1770 – 24 October 1848)
  5. The Hon. Henry Wellesley (20 January 1773 – 27 April 1847); later 1st Baron Cowley.
  6. Lady Anne Wellesley (1775 – 16 December 1844), married (1) The Hon. Henry FitzRoy (younger son of Charles FitzRoy, 1st Baron Southampton), (2) Charles Culling Smith.

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 have since been elevated to be Earls Cowley. Garret Wesley, Lord Mornington, died in 1781. He is also a direct ancestor of Queen Elizabeth II through her late mother, Queen Elizabeth The Queen Mother.

Garret Wesley died at Kensington, London, on the 22nd of May 1784, and was buried at Grosvenor Chapel. [1]

John, I would question 'Colley' as a second name at birth, however, I would investigate Wikipedia's use after the last name change,
