John Romney. Memoirs of the Life and Works of George Romney. London, 1830, pp. 178–79, observes that in 1781 Romney "painted a three-quarters portrait of the beautiful Emily Bertie for Mr. Pott, who took her with him to India, where they both died"; that he "also began a full-length of her in a recumbent posture, which was never finished" and that afterwards he gave the head to his pupil, Isaac Pocock; believes that Reynolds's Thais also represents Emily Bertie.

Humphry Ward and W[illiam]. Roberts. Romney: A Biographical and Critical Essay with a Catalogue Raisonné of his Works. London, 1904, vol. 1, pp. 94–95; vol. 2, p. 11, note that Romney painted Emily Bertie (or Pott, or Coventry) in 1781; record appointments for sittings with a Mrs. Pott on February 25, March 3, 10, and 17, April 20, and May 8, 1781, and a payment of £21 in September 1783 from Mr. Pott, but suggest that the sittings probably apply to a portrait of Robert Pott's mother.
