I’d say Susannah is the dancer, but neither Bridget nor Gwyneth seem particularly doctor-like or presidential to me. If I had to choose, I’d pick Gwyneth as my doctor, which leaves Bridget as the president, but again, the names don’t scream either of those professions. Susannah definitely seems like a dancer to me. Gwyneth could be a dancer too.
Have you thought of Claire or Clara? How about Victoria?

I love the idea of a President [name]Susannah[/name], for some reason. 
I think it works equally well for a doctor and a dancer, too (not to mention a writer, a mom, a teacher, a physicist, a judge, or a philanthropist).
I’m generally not Nameberry’s biggest proponent for [name]Susannah[/name], it just struck my fancy in your poll. It is a truly lovely name, though, it feels very sunny to me.
