While there she performed for Dublin audiences in Arne's opera Eliza, impressing them with her singing "perfectly in Time and Tune".
[4] The trip, however, was somewhat ill-fated as the Arnes' marital problems came to a head, partly arising from a dispute over Young's education, and Thomas left his wife.
Young remained in Ireland with Mrs Arne for the next seven years where she studied music with her aunt and performed in concert and on the stage in Dublin.
The Theatrical Review commented on her charming, innocent appearance: "Her performance on the harpsichord, is equal to her excellence in singing".
Young continued to perform in this way at Covent Garden for the next two seasons and then went on to sing minor parts with the Italian opera company at the King's Theatre in the autumn of 1764.
While on tour, Young sang in her husband's oratorio Jefte in Florence and gave concerts before Marie Antoinette and her sister Maria Carolina of Austria, the de facto Queen of Naples.
The family continued to prosper after returning to London in 1777, giving numerous lauded concerts in venues throughout the city.
Young complained in a letter to The Morning Post on 2 November 1784 that she was refused engagements, styling herself "an English Woman, of an unblemished reputation".
