Problem: Eric P. Hamp in his 2012 Indo-European family tree, groups the Armenian language along with Greek and Ancient Macedonian ("Helleno-Macedonian") in the Pontic Indo-European (also called Helleno-Armenian) subgroup.

The answer is the following: the northeast coast of the Black Sea and its hinterlands
