Uninspired for second girl's name

[TheKurgan]

Our first daughter is called Claudia (Claudie for short). We are really happy with her name and picked it because we thought it was a strong name, not too popular but not outlandish. Now I'm expecting number two and we're struggling to come up with a name we both like as much.
Any suggestions for a name that meets the criteria above? If it sounded nice with Claudia that would be a bonus!
Thanks!

How about....

Nina

Sylvie

Anna
Ruby
Annika
Rosa

I'd consider all these quite strong, not too trendy but not too 'out there'. How are we doing, OP?

Ooh, love Juliet and Lucille too. Or how about Eleanor/Eleanora?

Oooh, thank you, lots of food for thought there!

Of those suggested I particularly like

Penelope
Cassandra (but think we're trying to avoid another C)
Serena
Marianne
Juliet
Sylvie/Sylvia
Tara
Rosa
Rosalie

What about Rosamund, Kerenza, Mabel?

Kiya

Louisa

Marina

Miranda

Stella

Coralie

Sylvie and juliet are both on my list! I like Naomi too- felicity is a good suggestion to gwennan, but I may be biased on that one!

I have an Amelia and a Claudia!

I also like

Cassandra
Violet
Phoebe
Evelyn
Annabelle
Esther

Amelie

I have an Elena (pronounced Elayna). Thought it seemed similar in terms of sound/structure to Claudia. If I had another DD I like Nina or Francesca.

Flora

Claudia in The Babysitters Club had a sister called Janine.

I like:
Hermione
florence
Alice
Hebe

Claudia is lovely. I think that Naomi would go well, or Harriet.
