The sitter was the son of Captain Francis Lind, M.D., of the 14th Regiment of Foot and his wife, Elizabeth, daughter of Major Montague Farrer. He was born on 13 February 1753 and married his cousin, Ann Cooper, on 12 October 1785. He served in the Indian Civil Service. Datable to the mid-1770s, the sitter is depicted reclining before a music stand, holding in his right hand a one-keyed Simpson ivory flute.
Romney also painted the sitter's younger brother, Edward George Lind (b. 1754), whose portrait is signed and dated 1776, and his wife, Elizabeth, daughter of James Ainslie, M.D., who sat for Romney in the spring of 1787 and 1780. There is a memorandum on the fly-leaf to Romney's 1776 diary, 'Mrs. Lind, Carlisle, to be sent on Friday morning to the Castle Inn' - presumably the address to which the portraits of the Lind brothers were to be sent.
