Trading initially at 129 New Bond St but in 1781 moved to 20 David St, and by 1790 was at 24 Davies St. His trade was probably fairly subtantial, for as early as 1777 he carried an insurance cover of £500; by 1781 this had risen to £1,300 and by 1787 to £2,200. In 1785 he had a house on the north side of Berkeley Sq. [D; GL, Sun MS vol. 258, p. 522; vol. 328, p. 118; vol. 331, p. 555; vol. 342, ref. 532912]
