Hazel or Aveline - Aveline is a lovely French name.
Susannah or Liliana - Susannah for its Biblical pedigree.
Adela or Alice - Alice because I'm biased: it's my middle name. :)
Antoinette or Antonia - Antonia is gorgeous. Most "ette" names sound "dated".
Georgina or Georgiana - I love both names but I vote for Georgiana for its Pride and Prejudice association.
Felicity or Gwyneth - Felicity is such a "happy" name that it makes me smile. Gwyneth is too strongly associated with Ms Paltrow for now.
Nicole or Nicolette - Neither is a fave but at least Nicole doesn't remind me of Nicorette gum.
Sophie or Dara - I love the down-to-earth Sophie.
Jane or Jenica - Short sweet and simple Jane wins in a landslide!!! Is Jenica even a name? It looks like a modern smoosh of Jennifer and Jessica.
