I prefer
Susannah because I always thought it was the traditional spelling (although it appears now that it isn't, but the blurb on
Susannah /
Susanna has changed 3 times that I remember) and because I think
Susannah looks more balanced. Which do you prefer?
My cousin says
Susannah looks like someone trying to combine
Susan and
Hannah, which really turns me off. Do you think a lot of people would think that?
