I like almost every single one. They're all pretty classic, something almost unheard of for babies today in here in the US...
I'm guilty of liking
Lou for a girl but
Liv sounds too much like 'live', even if they don't speak English. Is it a nickname for
Olivia?
Stella and
Vincent is a lovely sibset. They really go well together.
Laura and
Anna are lovely as well, its nice to see
Laura on a little girl. And I always love
Charlie for a boy, but mostly if its short for
Charles.
And
Sara is a lovely name! despite popularity, I'll always love
Sara /
Sarah. Nice choice!
