I love traditional girls' names. Which could I get away with using?

[AKMD]

DC2 on the way and it's a possible girl :)

My shortlist is:

Annabel
Elizabeth
Lucilla
Lucinda

According to my mum we are not posh enough to use Lucinda (thanks mum!). Which do you like best from that list?

Do you like other french-ish names like Isabelle, Delphine , Amelie, Sophie, Anne-laure, Aurelie?
All nice though

Isabel is nice too.

my mum was a child of the thirties and told me the posh head girls name was Rowena .

but i love Veronica. or even Verucca Salt.
