A child prodigy, she started playing the piano at the age of sixteen months, and performed in public for the first time before she was two years old.

[1] Her father, Edward Randles, the organist at the Holywell parish church of St. James, lost his sight at the age of three as a result of small pox.

Perhaps due to his lack of sight, his parents placed him to be trained under the blind harpist John Parry,[note 1] under whom he excelled.

Williams-Wynn proposed that Randles play in a Wrexham concert during the spring of 1803, under the direction of the Welsh harpist John Parry.

[note 2][1] The concert was postponed a number of times due to the illness of Randles' mother, who insisted they carry on without her.

[1] By the time Randles was three and a half, she was invited to play for King George III, Queen Charlotte, and other members of the Royal Family.

There, she spent time playing with a young Princess Charlotte of Wales,[6] To ensure that she had sufficient funds for her education, Randles, her father, and Parry toured the rest of the United Kingdom between 1805 until 1808.

[7] In June 1808, she returned to London to perform at the Hanover Square Rooms, sponsored by the Prince of Wales and the Marchioness of Downshire.

[1] Randles moved to Liverpool, teaching harp, piano and singing regularly at a school in Ellesmere,[8] and returning each weekend to attend to her father until his death in 1823.
