When twenty-two, he married. The girl of his choice was Anne Maria Pickett, who belonged to a respectable family at Streatham, and who, after forty-five years of married life, was left his widow. They had one son and two daughters. The son died at the Cape in the same year as his father, 1833. One daughter was married to Mr. Smith, a sculptor, and the other to Mr. Paul Fischer, a miniature painter. Soon after his marriage he was invited by Sir James Winter Lake to take up his residence at Edmonton, where he taught drawing to their daughter, and doubtless had other pupils. When he applied (unsuccessfully) for the post of drawing-master to Christ’s Hospital, Sir James and Lady Lake’s testimonial made a point of the fact that he had never touched up their daughter’s work, “a practice too often followed by drawing-masters in general.” At this period Smith practised as an itinerant portrait painter, a branch of art which then had its vogue, and was to number William Hazlitt among its professors. At Edmonton it was that he “_profiled, three-quartered, full-faced_, and _buttoned up_ the retired embroidered weavers, their crummy wives and tight-laced daughters.” At Edmonton, too, he watched the reception of his first book, the _Antiquities of London and its Environs_. Smith’s career for the next thirty years may be conveniently sketched in a list of his residences and the work he accomplished in each. In 1797 he was at No. 40 Frith Street, Soho, a house which still exists, with its ground floor converted into a French wine shop. There he published his _Remarks on Rural Scenery_, consisting of etching of cottage and village scenes in the neighbourhood of London, with a preliminary essay on drawing. In 1800 he was living with his father at 18 May’s Buildings, or the “Rembrandt Head,” as it was styled, in St. Martin’s Lane. In this year the discovery of curious paintings during the alterations to St. Stephen’s Chapel for the enlargement of the House of Commons, attracted Smith’s attention, and, after making careful copies of these relics, he projected his _Antiquities of Westminster_. In February 1806, Smith published an etching of the scene on the Thames when Nelson’s remains were brought from Greenwich to Whitehall. He tells us that on showing it to Lady Hamilton she swooned in his arms. The plate is inscribed: “Published February 15, 1806, by John Thomas Smith, at No. 36 Newman Street.” This house remains unaltered. In 1807 he issued his _Antiquities of Westminster_, his address appearing in the imprint as 31 Castle Street East, Oxford Street. In 1810, May’s Buildings reappears in the imprint of his _Antient Topography of London_, but it may be that this address was not residential. The site of this house is merged in Messrs. Harrison’s printing works. In 1815-17, Smith lived at No. 4 Chandos Street, Covent Garden, whence he issued his _Vagabondiana, or Anecdotes of Mendicant Wanderers through the Streets of London_.
