Hi John,
Nicholas EMELLEN was the first registered Greek in Victoria who had the 'Corfu Mine' near Tarnagulla in Victoria.
Nicholas EMELLEN married Elizabeth ALLEN and had 3 children, Nicholas, Henrietta and Mary Ann. Nicholas junior was born in 1861. Nicholas jnr married Emily WRAY in 1886 and they had 3 children, Nicholas (1887-1911)), Ethel Ruby (1888) and Constantine (1890). Constantine married Ida Flora Ballard in 1913 and they had 3 children. Olive Millicent (1915), Constantine William (1917) and John R Clifford (1919). They all married in the 1930s or 1940. I haven't followed any further.
I am aware that Mary Ann married a Greek man and ended up in WA.
