Your previous claim was not true as most of those did not have Y-DNA. None of the Balkan sites have more than 20 Y-DNA samples.
These new ones you brought, yes, they have do Y-DNA, although 13 of those are outside the Balkans. And, again, you did not count them right because there are 7 Js there, and you only found 2. I told you to check in Croatia and Greece for Js. I counted all Y-DNA samples from 5000 BC, because the population was almost entirely replaced after that, and J is 7 out of 20-22. Even if you count all time periods it is among the main haplogroups, so again, using your own method, your idea that it is new to the Balkans is completely wrong. It is actually among the oldest and most widespread ones since at least the Bronze Age.
This conclusion is also easily reached by looking at other data that I explained above.

Be clear what you've found, with data for those 20-22 YDNA from witch, you say, 7 are Js, from what time you want. I have found in the area 69 ancient YDNA discovered so far, from witch 4 are J2a and 1 J2b. 3 of its (60%) are from Creta and Peloponnes and other two from Croatia.
Maybe I am wrong. So... what are your data about your 20 remains with 7 Js YDNA?
