William Eyre was born in 1791 and took over his father's business around 1814.
His father Isaac had died in 1808 but had originally set up in business from 1798 as Driver & Eyre at 19 Cockspur Street. Between 1800 and 1806, the business traded solely as Isaac Eyre. Between his father's death and William dealing in his own name, it is likely that his elder brother Isaac Jnr. ran the business and then continued at 11 Charing Cross when William took over Cockspur Street.
Although William advertised the Princes Regent and Saxe Coburg amongst his customers he does not seem to have thrived at business. He was bankrupted in 1821 and 1824. On the latter occasion he move to 258 Regent Street with Samuel Pratt taking the Cockspur Street premises. By the 1830's he is no longer listed in the directories.
