Her brother made her an allowance, and she went first to Devon; and then, in 1768, to stay with a Miss Flint in Paris, where Reynolds visited her.
On her brother's death in 1792 she took a large house in Queen's Square, Westminster, where she exhibited her own works, and where she died, unmarried, on 1 November 1807.
Of her work, Sir Joshua, speaking of the copies which she made of his pictures, says " "they make other people laugh and me cry;" but a letter of James Northcote's says that "she paints very fine, both history and portrait."
Samuel Johnson, who was very fond of her, and visited her in Dover Street, where she was living by herself in 1780, was not pleased with the portrait she made of himself in 1783, and called it his "grimly ghost."
Of her literary work Johnson held a higher opinion, and he was complimentary about her ‘Essay on Taste’ (privately printed, 1784).
