[name]Helena[/name] is beautiful and much less popular. Certainly underused in my view.
Wow, thanks for all the votes and feedback. We like both names, but are leaning towards [name]Helena[/name] which is consistent with the overall votes. We worry about the pronunciation variations with [name]Helena[/name], and felt like [name]Charlotte[/name] was a good choice that avoided that aspect. But, we did have concerns with the growing popularity of [name]Charlotte[/name].
