they are all correct. in greek language the female surnames are something like possessive form of the male surname.
as an example anna bulgari is the greek name for mr bulgaris's wife or daughter. same happens with frangoula goulandri as her being mr goulandris's wife or daughter and eleni stathatou as related to mr stathatos respectively.
unfortunately no other language happens to have differences in the male and female surnames hence we as greek ladies have trouble choosing whether we had better use our fathers surname or our own as we used to pronounce it in greece.
i think it is fair to use the appropriate own surname, in its proper female form, so we give a cultural hint, without saying that the other option is not correct.
so for your answer all aforementioned names are correct.
