Baptismal names in the Greek Orthodox Church! Where can I find an EXHAUSTIVE list of baptismal names in the Greek Orthodox Church; i.e an EXHAUSTIVE list of Names that have been given to a person (the frequency; i.e the number of people given each name are secondary) by the Greek Orthodox Church?

There are certainly some ancient Greek names like Alexandros, Leonidas, Aristotelis, Socratis, Hermis, Afroditi, Dimitra, Aris, Paris, Ektoras, Euklidis, Achilleas e.t.c

But others like Anaximandros, Anaxagoras, Dias e.t.c are unheard of. At least I know no person named as such.
Probably the only entities capable of figuring out the span and frequency of baptismal names, at least since September 1st, 1979 (a liturgical new year), are the Registry Department of each Archdiocese. You could try contacting them individually, although it's possible that their records are not digitized, in which case it would take a lot of effort to figure out your question. My modern Greek is only elementary, I am not sure if this is true outside of the Greek Orthodox church in America, unfortunately. 

As you may know, baptismal names are taken from the names of saints. Each saint has a day they're celebrated--often their date of martyrdom, if it is known. Therefore, calendars of "name days" will contain the names that are suitable for baptismal names. The two I have linked two are particular to Greek Orthodox saints. Of course, any Eastern Orthodox saint's name would be acceptable as a baptismal name, but each Patriarchate has its favorites!
