I already made a map of J2b three years ago. Upon someone's request I have created this map of J2b1 based on the available data. Unfortunately there is very little data at the moment for J2b1 outside the Balkans and some parts of Italy. Most areas in grey actually have no data rather than <0.5%. If you have more information, I will of course update the map accordingly.
J2b1's TMRCA is 5500 ybp according to Yfull, and many common subclades in the Balkans are much younger than that - only about 1000 years old. We now know thanks to Broushaki et al. 2016 that J2b originated in Neolithic Iran, and indeed J2b1 is particularly common today in Iran (2 to 5%) and is also found in Armenia, the Levant, Pakistan and India. This suggests that J2b1 has its roots around Iran, and arrived quite late to Europe, probably with some of the numerous peoples who invaded the Balkans from the Steppe, such as the Avars, Bulgars, Magyars, Khazars and other potential -ars. The presence of J2b1 around the Volga-Ural only strengthen this assumption.
The J2b1 in Greece, western Turkey, Italy, Mediterranean Spain and Libya more likely all spread from Greece. The highest frequency recorded so far is among Greek Cypriots (5.5%). It would have arrived with other J2 subclades straight from the South Caucasus or Levant. The question is when, since J2 was not brought by Neolithic farmers. The most likely time frame is the Late Bronze Age or Iron Age.
