My maternal grandparents were Greek . I believe they were born in Smyrna  & emigrated to Egypt. My grandmother Angela Diacopoulou was born in 1883 & had 2 brothers Yianni & Anastassios & 2 sisters Eleni & Konstantina. She married Alexandros Mouratis & they had 10 children. The 6 surviving  siblings were Andonis Polycarpos Paulina Eudoxia (my mother) Eleni & ia. I was told that the Diacopoulou family originally came from Kythera. Are there any Diacopoulou famililies in Kythera who may be related to my grandmother's family or anyone who might know of a Diacopoulou family who emigrated from Kythera to Smyrna in the 19th century ?
