I have found five entries for the GEERING shop in Hailsham, Sussex in early county directories, however the caveat exists that the evidence provided is not entirely reliable.
|1823/4||Geering M. druggist & linen draper||(Pigot’s Directory of Sussex)|
|1828||Geering M. chemist & druggist||(Pigot’s Directory of Sussex)|
|1832/4||Geering Mary, chymist and druggist||(Pigot’s Directory of Sussex)|
|1840||Geering Mary, chymist and druggist||(Pigot’s Directory of Sussex)|
|1845||Geering M. chemist & druggist||(Kelly’s Directory of Sussex)|
The first entry is quite interesting because it tells us that there was also linen available at the shop at one time. This, along with the description given by Thomas Geering in his book Our Sussex Parish suggests that the shop was more than just a chemist and druggist shop.
The other thing of note is that the name of Mary GEERING still appears in the entry even after her death in 1825. This might indicate the failings of the compiler, but it might also suggest that the shop still traded under the name of Mary GEERING, even after her daughter Ann had taken over the business.
