The sitter was the son of William Raikes (1738-1800) of Valentines, Essex, a director of the South Sea Company, and the nephew of Robert Raikes (1735-1811), proprietor of the Gloucester Journal, who was one of the principal figures behind the movement for Sunday schools which gathered momentum from the beginning of the 1770s until by the 1820s one and a half million children were being taught in them.
Job Mathew Raikes, of Theobalds Park in Hertfordshire, Chancellor House at Tunbridge Wells, and London, married Charlotte Susanna, daughter of Nathaniel Bayly, in 1798. This portrait is believed by Garlick to date from circa 1800-1804 (op.cit.). A full-length portrait of the sitter's wife and daughter by Lawrence is in the Virginia Museum of Fine Arts, Richmond, Virginia (Garlick, op.cit., no. 667). A portrait of the sitter's uncle, Robert Raikes, by George Romney, of circa 1785-8, is in the National Portrait Gallery, London (no. 1551) and a portrait of the sitter's brother Robert (1765-1837), who was a Governor of the Bank of England, is recorded in the collection of the Bank of England.
