My grandmather was married to my grandfather George Tzanes who is also from Kythera. My grandmather and grandfather had 4 children- Diamonda who died when she was 16, my mom Irene who is still living, my Uncle Theordore and My Aunt Bessie who are both deceased. I am looking for any relatives so I can trace back our family tree. I live in San Ramon CA, USA. Please write- I am proud to come from such a rich culuture and great family line.
