The discovery of Kot Choy!

While scanning through old newspapers on-line and searching “Tobias Hunter” I came across dozens of ads for rentals and real estate for sale. My grandfather had left Jardine Matheson and gone out on his own in Kowloon as an estate agent. 

One ad stood out and I initially thought it was a mistake, as the heading came up as “Silver Markets” I opened the page and a read down to the bottom. There it was, the day’s Silver prices, but off to the right was a small notice. It wasn’t very clear but my grandfather’s name was there. More importantly, was the other familiar name, Kot Choy and the addresses 11 Shelley Street, Hong Kong and 301 Amherst Road, Shanghai. From what appeared, Kot Choy and Anne Hunter were the same person. Who was Anne Hunter and what was her relationship?
