Gad
Gadeiros
Gadeiros was the twin brother of Atlas snd was known in Greek as Eumelos. It is generally accepted that he gave his name to the city of Gades, now Cadiz in southwest Spain. A more radical view is expressed by C. & S. Schoppe, who think that he gave his name to the Getae who occupied parts of today’s Bulgaria and Romania(a).
Others have sought to identify Gadeiros with Jacob’s son, Gad!
