Four small, independent Indo-European branches grouped here for browsing because each holds only a few live entities in this atlas, not a claim that Baltic, Armenian, Albanian and Hellenic are more closely related to each other than to any other Indo-European branch. Belongs here: Latvian and Lithuanian, the Baltic branch; Armenian and Albanian, each its own single-language branch; Greek and Ancient Greek, the Hellenic branch; and Proto-Indo-European, the reconstructed common ancestor of the entire Indo-European family, placed here rather than under any one branch because it is ancestral to all of them. Does not belong here: any language already assigned to Germanic, Romance, Slavic, Indo-Aryan, Iranian or Celtic above.
