Sorry for the confusion Phil, and for the delay in getting back to you. I have opened the laptop at home and being on South Pole Corner is correct (I was looking at the map the wrong way round and it was quite pixelated). I can not remember the no. , I was only there til 6 months old, and unfortunately both of my parents have passed away. My Brother thinks it may be No. 67, which is prob about right as the bank that now occupies the space now has a postal address of 79.
Any help would be massively appreciated.
