I think we have pretty different tastes tbh, Op. My thoughts, for what they are worth....
Noor - are you from an Arabic background? If so, yes, it's lovely. If not then definitely no, it would just be a weird cultural appropriation.
Thisbe - if your kid turns out to have a lisp, this will be a nightmare for her.
Delphi - sounds like a nightclub
Hebe - jeebie?
Elke - el-kah - not keen
Roksana - trying to work out how this is pronounced as the spelling is weird. Roxanna is better.
Corisande - Ok.
Cordis, Aleydis, Ardis all sound like boys names.
Olwen my favourite. Sweet.
Sasha - Ok
Saoirse - Nice but again would be weird to use if you don't have an Irish connection somewhere.
Viviette - prefer Vivienne or Yvette tbh.
