Rip - That would depend on the tribe of said leader. The first name that sprang to mind that would cause confusion was that of a Celtic king, Cunobelinus (who turns up, somewhat altered, as the eponymous characters in Shakespeare's play Cymbeline). In his case, the root is cuno-, rather than cun-, which is "hound" in Celtic, a totally different branch of Indo-European language (family tree here, but don't look at it after too many beers, he says, keeping tenuously on-topic! ;-) ).
