From the Peloponnese. three out of four of the Greeks in the haplogroup tree who are A2512 are from the Peloponnese.
I took only the 25 marker test, and I perfectly match another A2512 at 25 markers. I need to expand and take another test to confirm what looks like A2512 and even find the A2512 subclade.
So now we have a possibility that a different clade came to Greece from the north earlier than the Slavic invasion period. Until a few days ago I had no idea there was this interesting branch of I2a-Dinaric.
Thank you for reply Ralphie
Raf has explained distribution of haplogroups in Greece (Y-DNA haplogroups of Greeks by region of origin, page 11). I2a is high in Arcadia (20%) and Northern Peloponnese (25%).
On FTdna for Southern Greece we have following results:
S17250:
1x Z16971 -Kythira
3x PH908 (DYS448=19) Athens, Geraki, Kosmas
Y4460:
1 x Y4460* -Lagkadia
Z17855:
1x Z17855 Corinth
A2512:
2x A2512>A10959 -Arcadia and Sparta
1x A2512>A7134 - Messina
2x S17250- ,Y4460- ,Z17855- need A2512 – Arcadia and Zante
There are two dinaric north Y25 (one probably yours, other unknown location) which very likely belong to A2512. Also, a result on Ysearch, (from Diakopi or Dhiakopion, Greece) has close matches in A2512.
There are 3 more dinaric north results from Southern Greece (2x Peloponnese, 1x Agrinio), for them I cannot give any prediction about deeper subclade. The one from Agrionio is very interesting because have 9 or 10 markers of 111 tested that are slightly out of modal for dinaric.
In my opinion A2512 has started to spread around Mediterranean from Peloponnese. Except one from Thasos, rest of positive on this SNP are from The Peloponnese and islands around it. This branch has been also found in Spain, among Jews and Chuvash people from Russia. Tested A2512+ from Spain have Greek origin, also Jewish people might have paternal line from Greece according to Yfull tree.
A man from Chuvashia has completed a Big Y recently (I think) and he is assigned to A2512>A7134, maybe analysis of his results gives us an approximate time when A2512 in Southern Greece and East Europe split up. At least 3 branches of A2512 are present in Greece with TMRCA 2200 years, so very likely a group of people came there in period between 100. BC and 500 A.D
