I like
Arabella. It doesn't seem as fussy or frilly as other -bella names and I've only ever met one and she has always been compliments on it. I think it works well in real life and is the perfect mix of recognisable but very uncommon.
I think
Daphne Hilda Arabella is a mouthful. I still prefer
Daphne Winifred Hilda for flow.
Arabella Hilda Daphne could be nice
