Just noticed you have an Elodie, we really do have similar tastes!
If you go with Lorelei you will get reactions, some people absolutely love it, some are meh and some are rude!
I have been told it's a godawful name, that it's the most beautiful name ever.
I have even been told off as Lorelei has too many vowels (by the mother of a Louie
).
Clara is lovely but,to me, a tiny bit insipid and I couldn't shake the image of a servant girl. That's the thing about names everyone has different taste and associations with a name.
To me Lorelei sounds like music, to some people it apparently sounds like a stripper!
Just choose what you like!!
