The Danaans, Don, and Danu System
In the Iliad Homer uses the term Achaeans 598 times and the term Danaans 138 times. One might compare the father of the Greek Danaïdes — Danaus — to the Danaans, another name for the Ancient Ukrainian / Proto-Indo-European goddess *Danu. Compare Old Irish Danu whom the Tuatha de Danaan worshipped. Compare also the Indian Danavas descended from the Goddess Danu. Various rivers in Ukraine’s historical territory bear her name even today: The Don, Donets, Don Aper (Dniepr), Don Istris (Dniester), and Danube.

OxfordReference.com states ‘Danaan’ is ‘a word of unknown origin’ — they haven’t yet made the connection between ancient Greek as an Indo-European language that was born in ancient Ukraine. The D-N- system connects rivers, goddesses, peoples, and death-mythology across the entire IE cultural zone.
