No, I don't like Charlena at all. I don't like
Charlene either.
I love
Charlotta. I think it's a funkier take on
Charlotte and has a retro feel. It reminds me of
Anne of Green Gables - I think it was
Anne of the Island, specifically, which had a character named
Charlotta.
I'm trying to think of other names that start with Charl-. What about
Charlize?
