"Our understanding of the Macedonians' emergence into history is confounded by two events: the establishment of the Macedonians as an identifiable ethnic group, and the foundation of their ruling house. The "highlanders" or "Makedones" of the mountainous regions of western Macedonia are derived from northwest Greek stock; they were akin both to those who at an earlier time may have migrated south to become the historical "Dorians", and to other Pindus tribes who were the ancestors of the Epirotes or Molossians. That is, we may suggest that northwest Greece provided a pool of Indo-European speakers of Proto-Greek from which were drawn the tribes who later were known by different names as they established their regional identities in separate parts of the country... First, the matter of the Hellenic origins of the Macedonians: Nicholas Hammond's general conclusion (though not the details of his arguments) that the origin of the Macedonians lies in the pool of proto-Greek speakers who migrated out of the Pindus mountains during the Iron Age, is acceptable."
