Firstly, congrats on your news! How exciting for you! Ok, so here are some suggestions:
What about the name
Ruby? You don't like it at all? Because that would be the most obvious choice, if you want to honor your gma. I personally love the name, it's my fave actually.
The names from your list that I like are:
Azalea EliseHazelBianca
I do think that
Azalea might cause some problems though. I think people may find it hard to spell and even be confused as to the pronunciation. What about using it as a mn instead?
I like the combos
Hazel Bianca and
Shari Azalea. I think
Hazel and
Shari make a really pretty twin set. I also like
Phoebe Azalea,
Imogen Azalea,
Erin Azalea,
Meg Azalea,
Faye Azalea,
Roxanne Azalea,
Kathryn Azalea and
Celeste Azalea.
Hope that gives you a few more ideas. Keep us up to date about your "name quest"!
