I try to avoid names with pronunciation issues. jorjeeAHna? joreeANNa? You, and she, will get both, and might even get hit with the ludicrous jorJANEa. I'd willingly use
Georgina, but not
Georgiana and not
Georgia either - too geographical.
The main source of mouthfulness is
Georgiana. Middle names really get used so seldom. It's usually helpful not to have a vowel, like -a, followed by a vowel, in this case another A-. You could solve it by inserting a short, consonant-heavy mn between them:
Georgiana Clare Adeline, perhaps? Or
Georgiana Lynn Adele.
