The Germans have (or had) this trend of giving French names to their children, and sometimes the result is a bit weird (some young German people have old-fashioned French names for instance).
That's interesting, can you come up with any examples? (I'm not saying that you're probably wrong if you can't. It's quite likely that you noticed the fact and just stored that in your memory because it was remarkable, but forgot about the precise name.)
Also, to me as a speaker of Austrian (That probably makes a difference here!) German, the pronunciation NICK-oll sounds unutterably ridiculous.
