Unfortunately, it isn't until Harry Potter and the goblet of Fire that Hermione informs anyone that she prefers Hermyonee, so I had been happily calling her Hermeeonie for years as that is how my second-cousin who was twenty years older than I pronounced her name.
I think you are right, winterwhite, I dimly remember that Florence Nightingale was named for Firenze and her sister for Naples, due to their parents having spent their honeymoon in those places, or some such thing.
