Germanic tribe that Str. 7,1,3 counts among the weaker tribes, together with the Cherusci, Chatti and Chattuari. A version of the Mannus-genealogy ( Herminones) ranked the G., together with the Marsi, Suebi and Vandili, among the original Germanic tribes (Tac. Germ. 2,2). A connection with the Sugambri seems to be linguistically indicated, but the fact that Str. loc. cit. mentions both names in the same context argues against their being identical.
