Thanks so much to all who replied to this question that really had me stumped, I never expected to get such quick responses and yes after weeks of searching I believe I have found him and his family. Everyone who responded gave me a little more of the picture until it finally fell into place. And each chase is a learning experience, so maybe one day I'll be able to pay back your help by helping some other newcomer. BTW I am a decent photographer so if anyone wants photos of historical sites, graves etc around Sydney let me know...
