Which name is better?

All of the names are lovely and a really good way of calling her Abby (I ume you don't want to use Abigail). I would have to pick Gabrielle Imogen overall, but I actually prefer Imogen as a first name to Gabrielle, there's just the problem that you couldn't really call Imogen Abby! Oh and it's definitely spelt Imogen not Imogene.
