From early childhood, Wellesley showed talent on the violin, and soon began composing his own works. He attended Dublin University, 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), a double Anglican chant, and his Chant in E, from which the tune Mornington is arranged.
His son Arthur, the first Duke of Wellington, who defeated Napoleon at Waterloo, was the only one of his children to inherit some of his musical gift. Another of his descendants is Queen Elizabeth II of Britain.
The family name was changed to Wellesley in 1798.
