The Republic of Ireland is producing some excellent documentaries on the early history of Europe. This information is far more relevant than most North American anthropologists will admit. I translate most of the names of Uchee tribes with an Archaic Irish Gaelic dictionary. Even some of the tribal division names of the Creek Confederacy use Irish/Scottish Gaelic words as roots.
Most of the petroglyphs in the Georgia Mountains – Gold Belt are symbols from Neolithic or Bronze Age Europe.
