G2a is associated with the "Early European Farmers" (EEF) which in a European context first settled Thessaly (archaeological site of Sesklo) at approximately 7,510 BCE, and then expanded from there throughout much of Europe. The by far most prevalent Y-DNA haplogroup of the "Early European Farmers" (EEF) was G2a, namely some 61% of the total samples that have been tested till now. J2 has a frequency of 1.5%.

Much thanks!
