I love
Veronica. It's a known classic that is not overly used.
Veronica is elegant, timeless and regal.
Veronica adn
Sebastian sound wonderful together.
My grandmother was
Catherine Veronica, but everyone called her
Vera.
My cousin was named after her, but she goes by
Rona (which she altered to
Rhona to be more Irish.) I know another
Veronica who goes by Vee, and I had a babysitter growing up who was called
Rocky. (Of course, that was before
Sylvester Stallone's movies. I wonder if she kept it up.)
Anyway, loads of potential there.
Hope your dh likes it too. :-)
