Er ...
Ciar's people, actually. It started off perfectly literally, but that was many centuries ago, so you won't find traces of a man called
Ciar in county
Kerry today, where he once lived with his followers.
Kerry makes a convincing given name in English, close enough to
Gerry and
Kenny to look familiar, and benefiting from being both geographical and Irish.
As for the dark eyes,
Ciar means Black, in the same way that Karageorge means Black
George. Nothing to do with their morals or their skin ... just a dark-haired person originally. And therefore the original Karageorge and the original
Ciar probably did have dark eyes as well. But ciar or kara just meant black or dark.
And the spelling is very modern, but that's what parents are doing nowadays: like
Tracy becoming
Traci or Trasi. They still pronounce
Keri as if it had two Rs in the middle!
Hope that helps.
