Cymbeline

Not to mention, "rythmic"? :P

is it pronounced seembe-line or Seibelyn or different?

It is slightly irritating to make a boys' name page and then say that it can be considered for a girl name. According to your info, Cymbeline was a king. There was no girl named Cymbeline. Just because it SOUNDS like names that have been used for girl, doesn't mean it IS a name for girls.

I just googled it and it says soft C.

That's a good point actually, they are. Someone must know :)

I only wonder this because many Celtic names starting with a "C" are pronounced with a hard C sound. Just curious :)

I would've said soft, a hard C just sounds wrong. Although I don't actually know anyone with this name so I'm not actually much help.

Is this pronounced with a hard or soft C sound?

It is eccentric and light and rather effeminate in nature, at least by our 21st century standards. But the fact remains that it is a male name, and a rather beautiful one at that. But yet again, Nameberry, you delight in your attempts to market boy names to girls, and it's just not necessary or appropriate - especially since the feminine version of Cymbeline: Cymbelina, is perfectly viable and both ready and waiting to be used. So I suggest you make a page for that gloriously feminine choice, and leave Cymbeline with the boys, where it belongs.
