In 1847 father and son moved to 502 New Oxford Street London
In 1859 J C Reilly became Reilly & Co and moved to 315 Oxford Street (later named "Armoury House"), Joseph Manton's old premises and next door to James Purdey. E M Reilly stayed at 502 New Oxford Street. In 1860 Edward M Reilly became Edward M Reilly & Co.
From 1870 to 1874 E M Reilly & Co traded from both 502 New Oxford Street and 315 Oxford Street, and in 1869 Edward started trading as E M Reilly et Cie at 2 Rue Scribe, Paris; reportedly, this shop closed in 1872.
From 1875 to 1882 E M Reilly traded only from 502 Oxford Street leaving J C Reilly on his own at 315 Oxford Street. In 1881 315 Oxford Street was re-numbered 277 Oxford Street (Purdey was at 314-315 which, possibly because of sub-division and re-arrangement of the shopfronts/building, he called 314 1/2, it became 287-289).
The re-numbering of Oxford Street included No. 502 New Oxford Street which was re-numbered to 16 New Oxford Street.
At some time between 1884 and 1898 E M Reilly opened another shop in Paris, this time at 29 Rue du Faubourg, St Honore. When it closed is not known.
In 1898, on the death of his father, Edward inherited his father's business and closed at 16 New Oxford Street.
In 1903 a new shop was opened at 295 Oxford Street as 277 was to be rebuilt.
In 1911, probably on the retirement or death of Edward Reilly, the firm became a limited liability company, the directors of which were H Reilly and C W Roberts. In 1912 they moved to 13 High Street, Marylebone.
