Greeks in Nowra

I'd like to trace the whereabouts or get some information on some Kytherians who had lived and worked in Nowra or on the South Coast. Arthure Calligeros who owned the Nectar Cafe in Milton, Tom Zantos and Emanuel Trifelly who had worked in Nowra, Paul Calopedis who opened the Nowra Cafe in 1930. I realise that most of these people are dead, but if any of their family can tell me more about them I would appreciate it. It's for a history of the Greeks in Nowra being prepared by the Nowra Historical Society. Kiriaki Orfanos
