From the position of Goldsmith in Godwin's 1796 list we can deduce that the two first entries above were a different Goldsmith, very probably Charles Goldsmith 1737-1810 brother of Oliver Goldsmith DNB 1730-1774. He was a near neighbour of Godwin's at the Polygon in 1798 and the Commissioner's Room probably concerned the Land Tax. Charles Goldsmith was buried at St Pancras 16.3.1810 age 72 of Sutton St. He had married Sarah Gabandon in St Ann, Jamaica and she died about 1804 at Ossulton St, Camden Town. Contrary to his brother's DNB entry he was not childless, his children were Henry 1780-1833, Charles b. 1780, Ann 1782-1801, Catherine 1784-1865 married John Hanson and died Hoboken, New Jersey, USA, Daniel b 1789, William b.1791, Oliver Francis 1796-1828 married Margaret Davis 1822 in Jamaica (Ancestry user-submitted tree). The two entries in 1802 could well have been Charles Goldsmith as well, Lewis Goldsmith (see below) having gone to Paris in December 1801 (according to the DNB) and only returned to London briefly in July 1802 and then not till 1809. See McAdam for the two 1802 entries and see also Lewis Cs.
In the 1796 list Goldsmith appears early in 1801 and Godwin may have meant Mrs Goldsmith rather than Lewis Goldsmith DNB 1763/4 - 1846 as the diary suggests he met her at Sarah Elwes' two months before he met her husband, and the next entry suggests her first name began with S. In Lewis Goldsmith's will PCC 1846 he mentioned two daughters, the older one would have been born about 1793 when Goldsmith was in Germany, the younger Georgina was born in Paris in 1807 by his second wife. Other than the diary entries I have found no record of his first wife.
