Cassimatis Family

I am looking for those who are related to Harry Cassimatis who came to Australia when he was 19 in about 1910. His father was a priest and he was one of 14 children. He lived mainly in Victoria and ran cafes in Swan Hill with some of his siblings. I am the eldest of his great grandchildren and as he only had 2 children (one of which was my grandfather Talbot Menas Cassimatis, now deceased), I am seeking those who may have more information about Harry and his family.
Please email me at [email protected] is you might have any information that can assist me. Thank you.
