I just found this message and quickly phoned my mother about it. My mother is Politimi Tzetzeka (maiden name). Her mother was Maria Tzaneteas (maiden name). Her grandmother was Panagiota Tzaneteas(do not know maiden name) and her grandfather was Tzanetos Tzaneteas. My mother is from Kalivia Sohas.
Interesting note: My mother said that her grandfather did not want his first name to filter down to future generations. Therefore, there are no Tzanetos in the family.
