Vi har ju de kimbriska hövdingarna eller kungarna Boiorix, Gaesorix och Lugius, namnen låter keltiska men de lär ju ha varit germaner.
The known Cimbri chiefs have names that look Celtic, including Boiorix (which may mean "King of the Boii" or, more literally, "King of Strikers"), Gaesorix (which means "Spear King"), and Lugius (which may be named after the Celtic god Lugus), although this may not mean that they are Celtic as the elements could work in Germanic (compare the name of the Vandalic king Gaiseric, which is likely identical to Gaesorix).
