I've just reviewed the 1882 and 1894 directories and must admit I somewhat confused re numbering - certainly in 1894 #11 was occupied by several accountants but was it the same as in 1861+ 1871 - Pat may be lucky but it would be one of the few sections of the street to survive as much of the rest has been modernised or demolished & rebuilt - in the mid1880's G A Dean photographer vacated #10 for the delights of Finch Rd but #10 described as opposite the postoffice (pre Regent st of course)
