How can I find out if I have "real" Greek ancestry?

[Mortimer]

MyHeritage gives me 46,1% Greek. 23andme gives me "Balkan" and "unassigned Southern European" but Greeks get that too there is no Greek category on 23andme. Only Myheritage has a Greek category. Is there any good oracle on Gedmatch which can show Greek ancestry?

If they added a Serbian category onto MyHeritage much of your Greek would most probably be replaced with Serbian right?

I dont know. My serbian ancestry could be closer to greek then to some other serbs (who could be more slavic). Everything is possible.

I have a fifth cousin who is half Greek half Bulgarian from Northern Greece, and we talked quite a while via email. My Southern European admixture is around 5%, so yes, I do have distant Greek ancestry paternally.
