Clement’s first address in the Strand, recorded in 1800, was at number 220. The following year he moved to number 201, from where he published ‘Taxes 1801: Including the New Stamps – Clement’s Epitomised Taxes, Alphabetically Arranged’. The business moved again in 1811, to 11 Newcastle Street, Strand, as W.J. Clement, quite possibly a son, who continued in business until 1825
