Family

Hi I am wondering about relations in Kythera. My grandfather was George Samios and he had a sister Irene. He was born arounf 1900-1905. He came to Australia with his uncle and eventually they brought Irene over. Irene lived most of the time in Cairns Queensland. George owned several shops over the years one in Rosewood, in Brisbane - Mt Gravatt, New Farm. Does this ring a bell with anyone?
