Greek Silversmiths from the nineteenth century

We haven't been able to find a reference book on Greek silver (excluding Corfu silver). There are some listed in the reference book Ottoman Silver Marks. Smyrna (modern day Izmir) was a silversmith hub. Here is a list of nineteenth century Greek silversmiths we've come across:
