You're welcome.

Well as I see it you are rightly classified as A7136 but you did not do SNP's below V13? It's of course recommended, but I think you most likely belong to the Y3183>S2972>A7135>A7136>Y18675>
Y18673>BY5423 , all members of this clade share a value
dys19=14
with you, so that seems to be a value that separates BY5423 from other clades under Y18673. Closest to you on 67 markers is an Englishman.

So you see under E-Y18360
- Y18360* Chuvash
- A8458 Irishman, Puerto Rican, and also not on Yfull an Armenian
- BY5423 Bosnia, Macedonia. Not on Yfull also Bunyard from London and de Menezes from Brazil. This one from Bosnia belongs to an old family of Poblaćani-Vojinovići from Pljevlja area, their ancestor was a Christian Sipahi in 1608. Their origin might be from south (750 ypb distance with Macedonian).
Of these 3 clades
only BY5423 has dys19=14, so it is an important value to look for when searching for cousins.
TMRCA of you Englishman and Brazilian might be roughly around 1500-1700 ypb. On 67 markers you have 14 differences with Englishman, 17 with Brasilian, but between themselves they only have 12 differences, as you haplotype seems somewhat more "mutated".
There is a Greek from Kastania who is A7136, but haven't seen his markers.
So generally with this anonymous Greek haplotype from Crete (Crete and Southern Aegean as designated in the study) possibly belonging there, this clade seems to have possible/likely connection to Ancient Greece.
