Rosa Cassimatis extended family research

Dear Kythera Family,

I am researching Rosa Antonia Cassimatis extended family. Rosa is the mother of Lafcadio and James Daniel Hearn. She is my great-great grandmother. I understand the Cassimatis family came from Crete. I cannot find Rosa's mother name and relatives. I will be in Corfu this July. Feal free to contact me here or email to bradhearn@gmail.com or text/ WhatsApp to +1-954-540-5081. Warm regards, Bradford Hearn
