The English and the Celts - no genocide?

[authun]

We have coinage from the later first century BC/early first century AD that gives the names of rulers and occasional placenames. These come from the area suggested as Germanic-speaking, yet all of them are Brittonic Celtic. Why would supposedly Germanic-speaking peoples take Celtic names for their rulers?

Regarding Fitzpatrick-Matthew's question above, perhaps it is due to:

1. Celtic name elements having the same PIE root as germanic, eg. cf the Marcomannic prince Catuualda and celtic Cadwalla or the 'rix' element in the Cimbrian king Boiorix with germanic 'ric'

2. Roman or Gallo-romans simplifying the name, rather like we call München, Munich.
