Atuatuci

The Atuatuci was a part of the Cimbri that the main force had left
behind in the present Belgium, between Sambre and Meuse. Caesar
learns (VI,2,3) that "Nervios, Atuatucos, Menapios adiunctis
Cisrhenanis omnibus Germanis esse in armis", thus the Atuatici, hence
the Cimbri are not Germanic? Is there a Germanic etymology for their
name?
